[Vegetable seeds Daquan] How to sow the four principles of vegetable seeds to sow vegetable seeds

How to plant vegetable seeds

1. Regular land

Use Agricultural tools to open the land, soft soil, increase air humidity, and divide the ridge reasonably.

2. seeds mix soil

Because the seeds are too small, sprinkle it directly into the ground, and I am afraid that it is uneven, causing some seeds to grow, and some soils have no seeds.Therefore, mix with a little soil with a dragging soil and the seeds so that it is much more uniform.

3 Small

The soft soil can be scattered directly, and the whole land is only green when it is sprinkled evenly.

4. Cover soil

After sowing the seeds, a layer of soil should be on the ground cover to prevent the Solar from being damaged to the seeds.

5. Broadcasting skills

When sowing the seeds, you can't stand straight, and you must walk down and walk down and walk around. In this way, you can be uniform when you are swollen to the ground. If you are too high, you will also blow away the seeds, causing uneven sowing.

Four principles of vegetable seeds sowing

The first is to calculate the amount of sowing. According to the fields of seedlings, seed germination rates, and seedlings, there is a slightly excess planting, so as to avoid excessive waste.

The second is to treat seeds. Before sowing the seeds for 1 to 2 days, disinfection of the seeds to kill the pathogen bacteria carried by the seeds.The warm soup soaking method is soaked with warm water at about 5 to 6 times 55 C. Stir continuously and keep the water temperature for 10-15 minutes to reduce the water temperature to continue to soak.

The third is to carry out soaking germination to increase the seedling rate and neatness. The soaking germination time and temperature of different types of vegetables are different. For example, vegetable varieties such as high -temperature melon are generally soaked for 12 hours and requires about 30 C temperature.After germination of germination for about 30 hours, sowing, while the summer and autumn high temperature seasons are sowed in cold celery, coriander and other vegetables, while the temperature is required at about 20 C for about 24 hours.

The fourth is to flatten the seedbed before sowing, pave the nutrient soil, and pour the bottom water in advance. After the seeds are dried, sprinkle it on the seedbed.Straw, gymnasis, or Shading nets.Master the high temperature before the seedlings, and reduce the temperature in time after the seedlings to prevent the length.

How to grow Wheat seeds

1. Choose good breeds

The selection of good varieties with excellent quality, high single -plant productivity, strong resistance, high economic factor, and unrealized, which is conducive to achieving output targets of more than thousands of pounds.

2. Fine and neatly, balance fertilization

2.1 finely neatly

In order to improve the soil structure and enhance the ability of soil water storage to keep it, fine cultivation before sowing, plowing 23 ~ 25 cm, and returning orange stalks to return to the field.20~25cm15~20 cmPanasonic real, water storage and saving.

2.2 Do a ditch

building fields, establishing facilities for Wheat field irrigation and drainage phase, digging "Sanlou" ( , waist ditch, ground groove), and dredge the "three ditch" in time after spring to make the ditch be connected to meet the irrigation and drainage drainage.Require.

2.3 Balanced fertilization

According to the condition of soil comprehensive Fertilizer, the fertilization plan is formulated. It is mainly Organic fertilizer, and Organic fertilizer and inorganic Fertilizer are used to improve the organic matter content in the soil, thereby achieving the purpose of balanced fertilization.At the same time of cultivated land, you must apply sufficient base Fertilizer, 30 ~ 45 t/hectares of Organic fertilizer, pure N 225.0kg/hectare, P2O5 90.0 ~ 112.5 kg/hectare, K20 75.0 ~ 112.5 kg/hectare.Losses loss, avoid premature premature aging in the middle and late stages of Wheat, and move about 50%of nitrogen fertilizer to twice during the period of extraction to the pregnancy ears, so that the lysine and protein content in Wheat seeds are improved.

3. Moderate seeding period

3.1 seed treatment

Pharmacy should be planted or directly use coated seeds before sowing.

3.2 Sowing period

In order to cultivate strong seedlings, form a Wheat production group with well -developed root systems and a large number of stems, make full use of heat resources, and sowing the appropriate period to lay the foundation for the high -yield of Wheat.Generally, Wheat water holding the water in the field is 70%to 80%.Therefore, when the broadcasting period and soil are conflict, it is necessary to sow the sowing, which can be sowed for 3 to 5 days late, so that the Wheat is full of seedlings.Generally, when the average daily temperature, before the winter & gt; = 0 C, the accumulation temperature is best sowing at 16 ~ 17, 650 C, and 6 leaves and 1 heart seedlings can be formed during wintering.

3.3 Seeding amount

According to the characteristics of Wheat varieties and the amount of Wheat sowing during the sowing period, the semi -winter and weak winter varieties are sown in the middle and mid -October and the end of September, respectively.It is more suitable for sowing from mid -to -late October to late October to early November. The broadcast volume is 120 ~ 150 kg/hectares, and the number of broadcasts will be increased appropriately as the broadcasting period delays.The high -yielded fields above 700 kg/hectares, the basic seedlings can be controlled from 1.8 million to 2.25 million/hectares, and sowing can be reduced to 1.5 million to 1.8 million/hectares at the end of September and early October.For large spikes with low spikes, it is suitable for basic seedlings of 1.95 million to 2.7 million.

4. Scientific field management

4.1 Scientific fertilization and weeding

In order to prevent the phenomenon of non -seedlings from breaking the seedlings and ensure the safe and overwinter of Wheat, it is necessary to make irrigation in time to form a strong root.In order to make the prevention and control effect of weeds, chemical weeding can be carried out from mid -January to late February.From mid -February to the end of February, in mid -to -late March, 75 ~ 120, 120 ~ 150 kg/hectares were applied to promote Wheat back to green and unplugged and increased the division rate of Wheat.In early March, green water should be returned. The medium Fertilizer, low group and high Fertilizer, suitable or large -group Wheat fields are picked up in the first or early stages of extension, and the early stages of extension.

4.2 Chemical regulation to prevent falling down

Wheat is divided into two types: roots and stems. Generally, the stems are inverted, mainly due to the large amount of nitrogen Fertilizers in the early stage, resulting in too large Wheat groups, closed fields, poor ventilation and light transmission, long Wheat long and long, bases and bases.In the middle of the interval, Wheat Wheat occurred in strong winds in the later period.Therefore, in the production of Wheat, scientifically fertilize and water the soil.

4.3 Pumping and grouting maturity period

Wheat pumping and flowing flowers (mid and late April), in order to prevent Wheat aphids, pulp, insects, sticky insects, rust, pink pink disease, and red virus disease, extend the growth period of Wheat, increase yield, can spray pesticides, continuous use of 1 continuous use 1~ 2 times.At the same time, irrigation 1 or 2 times, the first irrigation is performed during the first spikes to keep flowers and granularity and grout to achieve the purpose of large grain, grain weight, and prevent early failure of the root system.Moisture and prepare for the second stubble crops.

5. Get in time

Generally, Wheat is basically mature in the early and mid -June, when the 2/3 of the Wheat ears of the Wheat field are brought yellow, and the end of the Wheat wax is the best harvest period.But Wheat should not be too mature, so as to avoid the seeds from falling off and reduce the harvest.Wheats should be separated from varieties for single, single sun, and single storage, so as not to mixed varieties and reduce the commodity and economic value of Wheat.

What is the best temperature for Wheat seeds to germinate

Wheat seeds can germinate at 4-37 C. The fastest temperature of the germination is 20-25 C, and the average daily temperature is most suitable when sowing at 16-18 C.The minimum temperature of Wheat germination is 0 C, and the maximum temperature is 30-35 C.

The agricultural meteorological indicators of the Wheat suitable for broadcasting are determined according to the actual survey and field trials.Generally, every time the main stem is added, a leaf age must be 70-90 C (low Fertilizer and drought time need to be accumulated more) before winter, and the accumulation temperature is 80-100 C for seedlings, so from sowing to division (3 leaves (3 leaves (3 leaves (3 leaves (3 leaves (3 leaves (3 leavesExpand), the accumulated temperature is about 340 C. Generally, Wheat seedlings grow 6 to 7 pieces of leaves and 3 to 5 stunts as the standard before the wintering.The most suitable date for sowing.

Before the winter, the accumulation of temperature or sowing a spike differentiation accumulated temperature is 450-700 C. Among them, the spring variety is 450-600 C, and the winter variety is 500-700 C.

Due to the instability of the Wheat broadcast period, the determination of the specific year broadcast period must be determined according to the variety of climate ecological adaptability and the weather forecast and agricultural conditions of the year.For example, the moderate Wheat broadcasting period in Beijing is 5 to 6 days earlier than usual, and the autumn warmth year can be delayed by about 5 days.

The moderate broadcasting period of autumn Wheat in plain areas across the country is mainly determined by temperature. The general upper latitude increases for each increase, and the sowing period is 4 days in advance.In the same area, every 100 meters above sea level, about 4 days in advance.In the northern Wheat in the northern winter Wheat area, the moderate broadcast period is from mid -September to early October, the Huanghuai Plain Wheat District is from late September to early October, and the middle and lower reaches of Wheat areas in the middle and lower reaches of the Yangtze River are from mid -October to mid -November.The district is from early November to late.

spring Wheat is suitable for the broadcast period. It is appropriate to sow the average temperature at about 0 to 2 C, and the sowing of the surface of the surface of the surface is 6 to 7 cm. It is best to control the day and night and sow.The Northeast Chunmai District is generally from mid -March to mid -April, early in the south, late in the north; the Chunmai District of the Qinghai -Tibet Plateau is about mid -March and late March; the northwest spring Mai District is from mid -March to mid -April, and the northern part of Xinjiang and the early south.In the same area, generally broadcast low -lying land, and it is better to broadcast high land.

Soybean planting

planting technology

1. Select planting

There is no big difficulty when choosing seeds. You only need to choose the large and full seeds. It is not as dry and dry.

2. Treatment

Gan the seeds before sowing, and the seeds in the dry state can better germinate.Before sowing, mix the seeds and stir with 0.1%-0.2%.

3. Soil

The soil plays a vital role in the growth of soybeans. Before planting, it must be sorted out by the soil. It is best to cultivate more than 20 cm. There are no other crops, and the soil should be fine.

4. Sowing

3 to 4 capsules are planted at one time when sowing, which can ensure the survival rate and survival rate of planting.The gap between the sowing is about 30-50 cm. Wet the water of the nursery with water. After the seedlings are sowed, cover the seeds with soil.

5. Management

After the planting is completed, it must be managed by it, and weeding is a relatively important job, because if weeds grow too strong, they will compete for the various resources required for its growth.The most common method of weeding is spraying the pharmaceutical agent, and try to make it as soon as possible.

Broad bean planting

planting technology

1. Select planting and sowing

When choosing broad bean seeds, you should choose excellent seeds with high yield and no disease.Before sowing, dug the land to plow to make the land softened. This is conducive to the root expansion of germination to form a root tumor, and then the use of rhizoplasses can increase yield.The method of inoculation of soil can be used to take about 100 pounds of soil in the soil that has grown in broad bean, and sprinkle it in the ditch during sowing.

2. Seedling management

Pay attention to the seedlings during the seedling period, and make corresponding control methods according to the situation of the seedlings.After sowing, cover with soil and cover the straw to maintain the temperature and humidity.In the middle of the growth period, it is necessary to prevent the prevention and treatment of pests and insect pests, deal with the onset plants, and remove the diseased body and weeds and destroy them.Spray pesticides for diseases and mice, control water, and organize branches.To ensure the normal development of the plant.In the later period, the plant's needs for water, control the density, and maintain the light transparency of the ground.

3. Following the Fertilizer and watering

After sowing, pour the water in time to maintain the required water, so that it can promote the early germination and seedlings.After sowing, the soil should be compacted to prevent the planting of the plants upside down.When you grow young leaves, you can appropriately apply small beam of nitrogen fertilizer, and during the growth period, you must apply phosphate Fertilizer and Potassium fertilizer.When pods, you should apply more trace elements, which can reduce the phenomenon of falling flowers and drop pods and achieve high yield.In the early stage, it is mainly necessary to ensure drainage and ventilation, otherwise the flower pods will fall and the Beans are dry.

4. Mid -cultivation

Check it in time after emergence.During the seedlings period, weeding should be cultivated frequently, and the soil auction should be thickened to prevent the upside -down phenomenon.Pay more attention to the seedlings of seedlings before and after the flowering period. The branches of broad beans are difficult to pod. The excess branches should be removed to absorb nutrients for the trunk, increase the result rate, and increase the full rate.

Pea

planting technology

1. Selected good varieties

You can choose to plant species such as Zhongnao No. 4, Zhongni No. 6, Baihua Pea, Doujian No. 1, Pod Eater 1 Pea No. 1, and American Bean Seedlings.

2. Select the plot

Vegetable peas are cool, but they are not resistant to high temperature, frost, drought, waterlogging. The soil is required to be moist but does not accumulate water.The period temperature needs to be maintained at 15-20 C, which is conducive to promoting flowering and pods.

3. Plant specifications

After plowing the soil, it is necessary to determine the width according to the characteristics of the variety and the drainage of the soil. The high -straw varieties are 1.5 meters, and the seeding of 2 rows of the gap is 2 meters.The variety is 2.5-3.5 meters, and 6 rows of seeding are sowed.

4. Sowing period

(1) Sowing can be sown in mid-to-late October. According to the row spacing of 40cm, the plant spacing is 20cm, the acupuncture points per acre are 2-3 capsules, and the amount of sowing per acre is 10-15 catties. Seedlings should be appropriately planted.

(2) The high-straw sweet pea, high-straw soft pod pea, according to the row spacing of 70-80cm, and 30cm of plant spacing, convenient for later management, mid-cooked dwarf varieties such as mid-pea No. 4 and Zhong Pea 6, you can choose to choose fromSeeding in late November, the amount of sowing per mu is 20 pounds, according to the row spacing of 30-35cm, the plant spacing is 10-15cm, and the amount of sowing per hole is 2-3 capsules.

5. Applying full Fertilizer

5,000 catties of rotten Fertilizer, 20-30 catties of potassium chloride, 50-60 catties of calcium phosphate before sowing before sowing, you can choose or acupuncture, or you can apply 60-80 catties of triple yuan Compound fertilizer to grow in branches and leaves. During the vigorous period, every 10 days, you can apply rotten Organic fertilizer.

6. Post -management

When the plant grows to 30-40cm, a few bamboo poles can be inserted in the pot soil. Direct vegetable peas can be climbed and grow. During the period, the stems and leaves should be evenly distributed.Bare, white powder, brown spot disease, root rot, withered disease, etc., immediately remove the diseased leaves, remove the diseased plants, and concentrate on fire for burning.

Mung bean planting

planting technology

1. Fertilizes on the ground

mung beans should organize seedbeds in advance before planting, probably about a week in advance.Dig deeper when organizing the soil, so that the pests in the soil can be eliminated, sprinkle some base Fertilizers in moderation after turning, and then flatten the seedbed.

2. Sprinkle seeds

Before planting, mix the seeds and resistance agents and stir it, so that the seeds should be covered with pharmaceutical agents to prevent diseases and insect pests.Dig a small hole every 30 to 50 cm during planting and sprinkle 3 to 4 seeds.Then sprinkle with a Compound fertilizer next to the small hole to cover the soil, which is conducive to the seed germination.Wait for 4 to 5 leaves when they are transplanted.

3. Later maintenance

After the transplantation is survived, weeding should be performed to avoid the phenomenon of weeds and plant disputes.In addition, it is not necessary to fertilize in its growth process. If it is sufficiently fertilized, it will lead to crazy growth and affect the flowering period. At that time

Red bean planting

planting technology

1. Fertilization

Red Beans need nitrogen fertilizer. Although there is a nitrogen in root tumor, the increase in farmhouse Fertilizer has a significant increase in yield. Especially in an appropriate amount, phosphorus and Potassium fertilizer are more significant.During the Fertilizer of Fertilizer, during the birth of Chilou, it can chase the speed and phosphate Fertilizer 5-6 days before flowering, which can promote the increase of flowers and prevent flowers and pods.

2. Management

In order to promote the developed root system, the red bean seedlings should be cultivated more and loose soil, and it is also beneficial to the growth of tumors.When it grows strong after flowering, it can be properly penetrated to remove invalid flower branches, so that nutrients are concentrated to pods, and the seeds are full.Before and after flowering, the most time -needed period of red Beans. At this time, water is short of water, which will cause a large number of flowers and pods.Therefore, water should be watered in time.Chi Doudou grows up in the early stage of the growth of aphids and red spiders, and in the middle and late stages of preventing and controlling heartworms to prevent pods.

Bean plantation

planting technology

1. Seedling management

(1) Temperature: The seedling period of vegetable Beans is about 25-30 days. The main tasks of the seedling management are temperature management. The temperature in the shed in the cauliflower is kept at 20-25 C during the day. , 2-3 days can be used for seedlings, and the leaves can be expanded in about 7 days.

(2) Rectifying the Fertilizer: The planting plot must be used for more Fertilizer. For medium Fertilizer plots, every 667 Square meters can be applied to a sufficient rotten Organic fertilizer 2500-3500 kg, and the calcium phosphate 15-20 kg.After fertilization, it can be turned into a deep. This can promote the development of the root. The depth of the soil must be more than 25 cm. After the rake is flattened, the north-south direction is made into 1.1 meters wide.

(3) planting: 1 day before planting, it is best to pour water for vegetable bean seedlings once, so as to prevent the root cause of injury when the seedlings are crushed.planting should be carried out on a sunny day, and when the vegetable bean seedlings are taken out of the seedbed, be careful.The row spacing is 50-60 cm, and the plant spacing is 40-45 cm.

2. Management management

(1) Temperature management: The temperature is maintained at 15-20 C during the day, and the temperature at night is maintained at 12-15 C. After 5-7 days, the temperature gradually increases the temperature.The temperature during the day is kept at 20-25 C, and the night is maintained at 15-20 C.At this time, the plants will give birth to new roots.

(2) Breaking: The second job of the pumping period is to prepare in a timely manner. Because vegetable Beans are vine plants, during the growth process, other objects need to be used to grow up.When the plant grows 3-4 pairs of true leaves, it is necessary to use a bamboo pole to build it, which is not only conducive to the growth of vegetable Beans, but also facilitates future management and picking.

(3) Fertilization and watering: The last job of the dumping period is fertilization and watering. When the plant grows 6-7 pairs of leaves, pump water once, combined with watering every 667 Square meters, pursue dilate. 15-20 kg, this can promote the pump.

Cowpea

planting technology

1. Land selection

The cowpea itself is more resistant to barren, so the requirements for soil are not high. General soil can be grown, but for the output and quality, you should choose soils with flat grounding, sufficient light, good drainage, and good breathability.In order to promote the growth of cowpea, before planting, it must be rectified, loose soil, and favorable for the growth of cowpea. If the soil Fertilizer is insufficient, the base Fertilizer can be applied to supplement Fertilizer. Generally, 2,000 kg of Organic fertilizer is applied per acre.

2. Sowing time

The warm climate of cowpea can be planted in spring to autumn. It can also be planted throughout the year through greenhouse technology. Generally, it is planted at 2- August. The temperature at this stage is suitable for the growth of cowpea, but it is from March to July.optimal.However, the climate and environment in various places is different, so when sowing, you must be carried out according to the local climate conditions to avoid the low temperature season.

3. Sowing

Sowing must first choose a variety of excellent quality. When sowing, the on-demand method is generally used. Open the acupoint by 40 50 cm according to the plant line, 2-grains per hole, and the soil can be covered by 1-2 cm after sowing.After covering the soil, water the water, and keep the ground film insulation and moisturizing to facilitate the emergence. However, it is necessary to pay attention when live broadcast in summer. It should not be covered with ground membrane to avoid the failure of the seeds to cause the seeds to germinate.Water, keep the soil moist to make it out.

4. Field management

Pay attention to moisture management in the early days of sowing and transplanting to ensure the emergence or survival rate. Pay attention to the time seedlings and the seedlings should be fixed when growing 3-4 slices of real leaves. Generally, two strong seedlings are left per acre.Make up seedlings in time to ensure Qi seedlings.Before pumping, it is necessary to settle in time to ensure good the field permeability. At the same time, pay attention to removing old leaves and yellow leaves to improve ventilation and breathable fields.After the seedlings are settled, they should be chaocated in time. A large amount of nutrients are required for the dumping period and the fruiting period.

Sword bean planting

planting technology

1. color

Choose in sandy soils with good drainage and irrigation functions. When the land, you need to make a monopoly gap when the entire land. The width of each ridge is about 30 centimeters, which can ensure that the drainage in the field is Smooth.Based on base Fertilizer, usually sprinkle a layer of livestock on each ridge.

2. Sowing

When sowing, the acupuncture is sowing, and the acupuncture points are dug at a distance of 40 centimeters at a distance of each plant, and then two to three seeds are placed in each hole.Can.

3. Fertilization

After the knife bean seedlings break out, we will be able to prepare weeding and fertilization. Generally, about one week after the seedlings are out of seedlings, we will cultivate it once.Fifty pounds of Compound fertilizer, fifty pound of Potassium fertilizer and thirty pounds of phosphorus Fertilizer can be poured in water.

4, settlement

Create a bracket next to each plant, then connect some ropes on the bracket, and then support the bean seedlings to the shelves to let them crawl and grow along the rope along the rope. This will not only increase the harvest of the output andThe daily management of the field is convenient.

Prevention and treatment of pests and insect pests

1. Root rot, epidemic, rust, white powder disease

The commonly used control methods are to spray the use of enemy Katsatsu, Bacteria, Daisen Zinc, and methyltotobadin. Spray every ten days and three times.

2. Aphids, South American spectrum, smoke, and aphids

40%liquid 40%liquid can be used, or 800 times liquid with the duves of the enemy.The South American spotted flies and smoke panels can be controlled with 10%imidacloprid wettable powder and 20%rice full suspension.

Lentil

planting technology

1. planting method

Multi -row of late spring live broadcast, the tender pods were harvested before the summer and autumn to the morning cream.Single or with corn, use corn straw as a bracket, or use it with garlic, can also be planted on the edge of the field.

2. Select excellent varieties

Select good varieties according to cultivation conditions.The existing lentils are divided into three types: white lentils, green lentils and purple lentils.

3. Field management

(1) Management of water and Fertilizer: There is less water during the seedling period, and more water needs to be extended after stretching and pods.Generally, 1-2 water is poured for a long time, and the flower pod stage is poured in about 10 days without rain.After watering, weeding is removed, combined with topdressing to prevent falling flowers and pods and long -term.Mid -cultivation should be shallow to prevent root injury.Organic Fertilizers such as rotten chicken manure can be applied before pods.After pod, a small amount of Chemical Fertilizer is applied.

(2) Bringing the vines and pruning: Before pumping, you must fight, or use a rope to attract the vines and go to the house after pumping.When the main vines are 5-6 compound leaves, the top of the blades will promote the multi -hair vine. When the side vines are 3 to 4 leaves, they can be topped.Generally, if you are cultivated with a hedge or human character frame, you can promote precocious pods when the stem vines grow to the top of the frame.

Prevention and treatment of pests and insect pests

1. Leonue rust, brown spot disease

Prevention method: Using 70%methyl sulfurus 100 grams or 37%phenyl methyl o'cone 20 grams of water 60 kg of water spray prevention and control.

2. Leonnel night moth, small gray butterfly and smoke green worm

Prevention method: 3.3%Avi high chloride 15-30 grams or 30%Aviwei Poisonous death 40-60ml of water 60 kg of spray is controlled.

Jaose

planting points

The jute -based tropical and subtropical crops are suitable for high temperature and humid climate above 20 C. The minimum temperature of germination is 13-14 C.

Due to the small jute seeds and weak top soil ability, it is very important to create a good soil environment when sowing.Generally, after the last harvest, the land plowing is rated in time.

The Yuanguo Rather was sowed from late March to early May. The seeds of the fruits were sowed from late April to mid -May, and the south was earlier in the north.

The upper part of the seedlings grows slowly, and they are afraid of waterlogging and drought.

The Tattoo tissue tissue contains newborn fibers and secondary fibers. Primary fiber comes from the primary elementary tissue. The fiber beam is long and the texture is soft and good.increase the proportion of primary fibers and improve fiber quality.

The number of valid plants per acre, the round fruit jute should be about 14,000 plants and the fruit has about 18,000.From June to July, it entered the long run, and Ma strains grew rapidly, and it grew about 5 cm daily.

After blooming, it enters the reproductive growth stage. When the plants are half -flowering and half -fruit, it is about half a month after flowering, and it is a mature harvesting period.The seedlings are cultivated or inserted with the original plant.Generally, when the fruits become brown, it can be harvested.

Prevention and treatment of pests and insect pests

brown spot disease

symptom:This disease is also called jaoseki leaf spots or spots. The penetration of jute can occur. It mainly invades the leaves.The leaf spots are close to the irregular shape, yellow -brown to brown, the edges are darker, and the diseased parts are clear.

Control method:

(1) Timely turning after harvest will help the elimination of germs in the diseased and disabled tissue and reduce the source of infection.

(2) Institute of normalized areas and severe illness fields advocate rotation, especially water and drought work.

(3) Broadcasting healthy and full seeds, and sowing in an appropriate period to prevent premature sowing.

It is best to choose a place for the sun and drain well in the planting place, but the strength of the light should not be too strong, and the low water level should not be planted below 1 meter.It can adapt to sand soil to sticky soil, but the soil with loose soil grows best.

Sowing seedlings

During the sowing time from early March to early April, select the market conditions as seedbeds, apply enough base Fertilizer, and seakules can be sowed in fine rake.

The germination rate of general sowing is 30%, and the amount of sowing per acre is about 1 catties. During sowing, it is sowed with fine mud or plants ash. Pour water permeability once before sowing. The first layer of straw and crop straw, heat and moisturize.

After sowing, keep the soil moist. After the seedlings are emerged, as the seedlings grow, the coverage is gradually removed, and all the seedlings can be removed when the seedlings grow 6 slices of true leaves.

The timely interval seedlings during the seedling period can quickly grow the seedlings and increase the yield. Generally, the seedlings are generally performed during the 4 leaves. The 6 leaves enter the second seedlings. The plant spacing is 4-5cm, and 400-500 plants can be planted per Square meter.

While the seedlings, the diseased plants and weak seedlings can be removed to remove weeds, spraying potions to prevent disease pest pests. During this period, there are 1-2 times to loosen soil.The sprouts are neat, and there is also a layer in the sealing period, 4-5cm in China.

Fat Water Management

After the coverage is removed, the soil should be wet and wet. By the 3-4 leaf period, it can be properly applied with watering. At this time, some urine and Fertilizer can be applied in an appropriate amount, once a week, 2-3 times per week.

When the seedlings grow to about 20cm, the seedling Fertilizer should be applied at this time to promote the rapid growth of the seedlings. At about 60cm, they pay attention to long stalk Fertilizer. The Fertilizers are generally human and animal dung, cake Fertilizer or Urea. Generally, people and animals are applied per acre1000kg of Fertilizer and urine home, 100kg of cake Fertilizer, and 20kg of Urea. A small amount of boron Fertilizer can be applied in the peak growth season, which can increase yield.

harvest

Castle is a crop that has been harvested many times. The first harvest is in late May or early June. The head hemp is harvested early, prompting Erma early hair, and repeated work after harvesting.

The same inter -seeded weeding and Fertilizer and water management. The two hemps are generally in late July. After harvesting, weed, weed, and fertilize. We must also pay attention to the prevention and treatment of diseases and insect pests and promote the healthy growth of Sanma.

In the late summer and early autumn, the disease is severe, and the climate changes are large. In addition to pests and insect pests, it is also necessary for drought and autumn and waterlogging measures. Sanmu can generally be harvested in late October or early November.

Prevention and treatment of pests and insect pests

The main diseases are: root rot nematodes, white -grained feathers, rising diseases, and blue blight. In addition, there are anthracnose, corneal patients, brown spot disease, bronopathy, mildew, and cornal corruption.

Pests are: night moths, red pupa butterflies, yellow puppet butterflies, and sky cows.In order to harm the turtle, there are copper green Turtles, big black golden Turtles, and black velvet Turtles. In addition, there are ugly butterflies, silver -wicing night moths, and leafylons.

Rapeseed

1. Sowing

Big leaves must be planted after seedling.The seedling bed should be selected with good water retention and Fertilizer. The seedbed is 1.0 to 1.1 meters wide. The amount of Fertilizer in the bed is the same as green vegetables. It uses a strip, the distance between the strip is 5 cm, the ditch is 1 cm deep, the planting distance is 2 to 3 cm, and the feet are poured before sowing.Bottom water, sowing the soil.winter seedlings are carried out in the greenhouse.After sowing, cover the small arched shed to heat up. After the seedlings are unearthed, a layer of fine soil is covered. The seedlings are 3 cm after the citrles are expanded, and the seedling distance is 3 cm.At the time, the seedlings are properly loose and weed, and the seedlings are prepared to be planted when they grow 3 to 4 leaves.

2. Land and planting

7 to 10 days before planting, fertilized the whole land, and permanently applied 2,2500 kg of composting, turning over the land, flat land, aspiration, 1.1 meters wide, 3 lines of planting, 35 cm 35 cm, large leaf mustard roots slower hair root root, The fast and slowing after planting is related to the planting technology. Be careful not to hurt the roots when planting, so that the root system will twist and hang out.

3. Field management

Watering for 7 to 10 days after planting, it depends on the seedlings.Big leaves must be used for leaf vegetables. The topders are mainly nitrogen fertilizer. Because the northern region is listed on the market with 7 to 8 leaves. The topdress is generally 1 to 2 times.150 to 225 kg, chasing Fertilizer again as depending on the situation.In winter, protective land planting pays attention to ventilation and replacement, cold and heat preservation, the temperature during the day is controlled at 15-20 C, and at 5 C at night.

4. Harvest

Because it is consumed by small strains, about 7 to 8 leaves can be harvested at any time as needed for 40 days.

Peanut planting

planting technology

1. Choose full and strong seeds. Sowing can be sowed in spring and summer seasons. The sowing in soil 4 to 5 cm deep. The temperature in the soil should not be high or low, between 15 C and 20 C.

2. When the soil is moist, the water is sufficient, the temperature can be germinated when the temperature is 24 C to 38 C.

3. The Fertilizer should be sufficient. In the early stage, in order to make it strong, we must cut off the surrounding soil and expose the leaves.

4. When there is a worm, it should be controlled in time, and spray with 40 % of the fruit milk oil with 40 %.

5. When it grows to the middle period, apply more Fertilizer and appropriate, watering more, and watering when you see it. At this time, it is an important period of growth to prevent insects in time.

6. To prevent leaf spots, the disease spreads with 50 % multi -bacterial spirit 1000 times liquid. When the leaves become yellow, the peanuts are mature, and you can pick it up.

Flax

planting technology

1. Select planting

seed treatment: seeds should be selected before sowing, thoroughly clearing the silk, grass seeds, and public hoods, as well as impurities such as seedlings and soil grains, so that the clarity of the seeds can reach more than 95%, and the germination rate is more than 90%.

In order to prevent the treatment of flax seedlings, seed treatment must be performed before sowing.4 5D before broadcast.The anthrax blessing is mixed, and the dosage is 0.3%of the amount of the seeds for prevention and treatment.

2. Sowing

(1) Sowing period: When the depth of the sowing depth is stable at 7-7.5 C, the soil water content is not less than 20%, and sowing is generally sown from late April to early May.

(2) Sowing quantity: It should be determined based on soil fertility and the number of seedlings.

Land with high soil fertility, 15 to 18 million seedlings per hectare of seedlings, sowing volume is 105 to 112.5kg/hm2.

Generally a fertile plot, 1350 to 15 million seedlings per hectare of seedlings, and sowing volume is 97.5 ~ 105kg/hm2.

Poor Fertilizer plots, 1200 to 13.5 million seedlings per hectare, sowing volume is 90-97.5kg/hm2.

(3) Sowing method:Vellet seeds are small, and the top of the leaf is weak, and it is suitable for shallow broadcasts.Generally, when the soil is good, it is advisable to cover the soil with 2.5 to 3 cm.If the soil is poor, the soil can be slightly darker (3 to 4 cm), but it should not exceed 4 cm.Otherwise, the seedling rate will be seriously affected, and the seedlings are not strong, causing production to reduce production.The row spacing is generally 15-20 cm, and the longing of a loser is 30 cm under the conditions of exemption.

3. Fertilization

When applying Organic fertilizer, Chemical Fertilizer is appropriately applied to have a good production effect.Chemical Fertilizers can be used in the soil before sowing or sowing.The amount of application should be determined according to the type of soil, fertility, pH, soil, plant density, and output indicators.Light -alkali soil type is proportioned in nitrogen, phosphorus and potassium of 1: 3: 1, and the black soil type is 2: 1: 1.Incidentally, zinc Fertilizer, copper Fertilizer and other micro -Fertilizer have also been applied, and there is also a significant increase in yield.

sunflower planting

1. Treat the seeds

Dry the seeds to be broadcast for about 2 days, soak it with water for 6 hours, and finally use 50%of the wettable powder to sterilize. The amount can be referred to the instructions to lay a good foundation for future diseases and insect pest control.

2. Treat the soil

The most suitable soil for planting sunflowers is loam soil and sandy loam soil. This type of soil has a good structure, high fertility, loose soil, which is conducive to root development. It can provide good nutrition, moisture and air, which is conducive to the stable production and high yield of sunflowers.

3. Sowing

The sunflower sowing is best to use the excavation method. The depth of the planting acupoint is generally 3 to 4 cm, and the drought can be slightly darker.Each acupoint needs 2 to 3 seeds.

4. Field management

(1) Weeding: Timely weeding is an indispensable guarantee for high yield.

(2) Following pursuit: When the sunflower is eight leaves, we start to pursue pursuit, chase 7-10 kg of Urea, and 10 kg of Potassium fertilizer.Spray boron Fertilizer again during the sunflower's buds and flowering period.

(3) Breeding. Generally, there will be a lot of small forks in sunflowers that need to be taken off, and the yellow leaves below also need to pour off about 4-6 yellow leaves.

(4) Following: Adopt a flower dish contact method or pollination with powder puff.When the flower blooms 30, it is divided once when the flower blooms 50%. When the flower blooms 80%, it is suffered a powder three times in total.

Prevention and treatment of pests and insect pests

1. Nuclear Copycinosis

Prevention measures: In the early stage of the settlement, it can be selected for spray prevention and treatment of pharmacy such as Spechen, bacteria nuclear, agricultural and liking, tattoos or polymorphic spirit, and focus on protecting the back of the flower plate.Because the sunflower plant is tall in the later period, the spraying operation is more difficult, and the method of moisture reducing the pole to the field after rain.

2. sunflower

Prevention measures: Before the sunflower flowering period, larvae before entering the seeds, spray enemy cachines, and prevention of more than 90%, but it is harmful to bees and causes more shells.BT emulsion dilute spraying.The areas that are severely harmful to prevent adults and prevent the control of larvae. At the end of July and early August, the adults were fumigated with the enemy's downs or a diverse cigarette agent.
