[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.

What are the types of pasture seeds?

Types of pasture seeds

Many pasture varieties, native to produced domestic and foreign countries, are divided into east, west and south.Adapt to a specific climate ecological environment.Therefore, the selection of pasture and grass species and varieties should be considered according to the climate, sunlight, soil conditions, the use of pastoral grass use, and the adaptability of pastoral varieties. For example:

1 , Northeast goat, , sand Dagang, Hu Zhizi cultivation area;

2 , Inner Mongolia Plateau Sandwang, Old Mangai, Mongolian Rock Astragalus Cultivation Area;

3 , Huanghuaihai, Shada Wang, Mangque Wheat, reed -like pine cultivation area;

4 , Loess Plateau , Sandawang, Little Crown flowers, Mangbi Mai Cultivation Area;

5 , White Three Leaf, Watana, reed pine, and cymbal cultivation areas in the middle and lower reaches of the Yangtze River;

6 , South China wide -leaf sparrow, Dog tails, wing Beans, Yinhehuan cultivation areas;

7 , White Sanye, Wiculose, Red Three Leaf, Reed Catal Cultivation Area;

8 , Old Mantai, Pooe Ploves, Chinese Cinema, and Catal Cultivation Area;

9 , Xinjiang , Mango Mai, Old Manga, Wooden Skin Cultivation Area.

The above division is not absolute, For example, the planting of the Yellow River Basin in my country has proved that the crop sweet potatoes, cotton, and sugar cane transplants in the tropical subtropical regions have succeeded in the northern region. planting in the wrong season, moderate control of Fertilizer and water, promoting the director, avoiding its shortness, and the introduction of pasture varieties across the region carefully, there are also better gains.

Where can I sell the seeds of pastoral grass

How to choose different varieties of pasture seeds?

The price of pasture seeds is 30 Around Yuan, but in the face of so many varieties of pasture seeds, many buyers will be confused and do not know how to choose.Xiaobian provides you with several selection solutions for reference.

1 According to the regional climate, choose pasture seeds.If the climate is dry, it is suitable for choosing drought -resistant pastoral seeds. If the climate is cold, it is best to resist the cold on the basis of drought resistance. Purple flowers are a good choice.

2 According to the type of soil type, choose pasture seeds.Like Sandow Wang, it is more resistant to salt and alkali, so saline -alkali or alkaline soil is suitable for choosing this variety of pasture seeds.Red and white three -leaf are more acid -resistant, which is more suitable for planting in some acidic soil.

Pastor

3 Pick the pasture seeds according to their uses.The seeds such as forage for feed are mainly purple flowers, red, white three leaves, etc., because these pastoral seeds grow well in the early days and can be harvested in a short period of time.For example, the seeds used for grazing are three leaflasses, rye grass, etc., because these pasture seeds are relatively regenerative.

4 According to oral sex, choose pasture seeds.Different livestock has a good grasses that are well -preserved, and can be adjusted according to the specific.

In addition to selecting the right seeds, you must also pay attention to the quality of pasture seeds and buy it in regular manufacturers.The seeds bought at the same time should be stored in a dry environment and maintain a suitable temperature.The quality of the seeds will directly determine the quality of the pastoral grass that is produced in the future.

The germination of the pastoral seeds

Choose a place

The requirements of pastoral grass on the growth environment are not particularly high, so it can be cultivated in any sporadic land.However, if you want to plant pasture and get better output, the selected land should have better water and Fertilizer conditions.After selecting the land, clean up the whole land, clean up the stones and weeds, and deepen the appointment. 20 centimeter.After plowing, we should continue to apply bottom Fertilizer on the land to ensure that the growth of pasture grows is sufficient.Generally speaking, the amount of fertilization is maintained per acre 20-30kg Compound fertilizer and 2000-3000kg Farm Fertilizer.Perform the ground after fertilizing.

Seeding

The choice of pasture types should be decided based on the local terrain and climate conditions. Choose the proper pasture seeds that are suitable for growth. It is best to be the seeds that local breeding units have studied and cultivated after years of research and cultivation.

After selecting the type of pasture (variety), choose a regular business or unit to buy seeds.When buying seeds, pay attention to whether the quality standards of the seeds on the packaging, and find out information about the origin, number of the seeds.

sowing

From the perspective of climate, the sowing work of pastoral grass is suitable for the two seasons of spring and autumn.The reason is as follows:

1 The conditions for temperature and humidity are more appropriate;

2. In these two seasons, insect pests occur less, or pests are easier to prevent and control;

3 Suitable for the growth and development of pasture.However, my country is vast, and the geographical conditions in various regions are different, and the sowing time should be adjusted accordingly.

Field management

If you want to maintain the growth of pasture, the most important thing is to do a good job in field management, water and fertilize appropriately, and timely remove the weeds to eliminate pests, and provide a good growth environment for pastoral grass.Among them, the management of water and Fertilizer is very important. We need specific mastery: After the pastoral grass is divided, dialing, or cute buds, we generally need to add Fertilizer, mainly applied speed -effective nitrogen fertilizer, and at the same time, a certain amount of phosphate Fertilizer and Potassium fertilizer can be applied according to the growth of pastoral grass.As for the frequency of irrigation and irrigation, it is necessary to determine according to the type of pasture. For example, the water content of the soil needs to keep the water content of the soil 55% The left and right, and the shadowee needs to be 75% about.

If you want to grow up healthily, we should complete the land selection and seed selection work at the beginning. During this period, we must patiently carry out field management. We must always pay attention to the growth of pastoral grass in order to be high -yield.

[Lettuce planting] Lettuce seeds Low -temperature germination method of lettuce cultivation method

The method of picking the lettuce seeds

The lettuce is planted by the spring lettuce of the winter lettuce, and the varieties of planting plant are separated 1000 About meters.Select plants with strong growth and strong characteristics of this variety. 33 See the Square above centimeters, remove the old leaves, add Fertilizer water, cultivate soil, and promote the growth of the side branches.

When blooming, some branches are properly removed, the pillars are inserted to prevent falling, and the flowering period cannot be dehydrated. 20-25 God, the leaves of the planting plant are yellow normally, the seeds are brown or silver -gray, and the white crowns are harvested in time.

How to deal with lettuce seeds

autumn lettuce is generally 7 Monthly 8 Sowing at the beginning of the month, this is the high temperature and hot season, and the seeds are not easy to germinate.Measures such as low temperature treatment, hormone soaking, red light irradiation, etc. in production are often used to promote germination.

1 , Low temperature treatment is the most commonly used method, that is, soak the seeds first 12--24 In hour, put the seeds in a cool place such as caves, wells, or directly placed in the refrigerator, and keep 25 Below and humid conditions, scriptures 3-4 After the heavens, wait 80% seeds can be sowed when germination.

2 , Use hormone soaking, then 100 Milligram / / The hormone soaked in the seeds 3 In minutes, sowing after rinse can greatly improve the germination rate of lettuce seeds under high temperature conditions.use 0.1% Sulfur treatment can also promote germination.

3 Use red light to shoot lettuce seeds, which can also promote germination at high temperatures, but infrared rays can inhibit germination.

The method of low temperature germination of lettuce seeds is as follows:

First, soak.Soak the seeds with water before germination 7 8 In the hour, the buds are neatly sprouting.

Second, the refrigerator is low -temperature germination.Put the seeds soaked in water in the refrigerator refrigerator and adjust the temperature to 4 , refrigerate 72 In hour, then take out the seeds and put them in the shade and humidity.

Third, the Hanging well is low -temperature germination.You can also put the seeds soaked in water in the cloth bag and hang it into the well. The seeds leave the water surface. 10 Centimeter, time 7 Around the sky, wait for the seeds 80 Take out the sowing when % dew.

The sowing time of lettuce seeds

1 , spring lettuce: 12 Monthly 3 Moon green shed, 2 To mid -month 3 In the end of the month, open -field seedlings.

2 summer lettuce: 4 Monthly 5 In the middle of the month, open -field cultivation, 5 Arrived in the end of the month 7 Monthly uses a shade net to be planted live or high -density.

3 autumn lettuce: 7 Monthly 9 Monthly uses the Shading net to cover the sowing and transplant seedlings.

4 , winter lettuce: 10 Monthly 11 Moon exposed seedlings.

Lettuce planting method

1 Following ground fertilization

The roots of lettuce are shallow and the absorption capacity is weak. Therefore, it is better to choose a loose sandy soil for the soil. Choose a high -level, well -drained and dry plot. Apply the bottom Fertilizer before sowing.Crack, then flat, cover a layer of coverage to prepare for planting.

2 ,sowing

In order to ensure the Smooth germination of the seeds, the seeds need to be treated before sowing, soak the seeds in water 6 At about hours, then wrap it with a wet towel to start germination.After germination, sowing can be sowed. The seeds of lettuce are relatively small, so stir the environmental soil during sowing and sprinkle it after sowing. 2-3 Gich, cover a layer of shallow soil after sowing.After sowing, cover a layer of film, heat thermal insulation and speed up, and observe carefully. When the seedlings are unearthed, immediately open the film to keep ventilation and light. 3 You can be planted when the left and right true leaves.

3 Plant management

To ensure that it grows rapidly and strong when planting, it should be kept distance and row spacing 25cm 30cm , Timely watering to promote the development of the root system, and keep the soil moist. If the planting is a high temperature period in summer, proper Shading should be appropriate to prevent the seedlings from being harmed.There is no need to fertilize after applying foot Fertilizer. It can be applied to the farmhouse with light Fertilizer once or twice when combined with medium or weeding. It is also necessary to pay attention to the shallow roots when China cultivation. Its root system is not developed.Root system.

[seed saving box] How to open the seed saving box of the seed saving boxSurgical parameter

How to open the seed saving box

seeds need to grow into healthy plants and make fruits. They need to go through the germination stage. At this stage, the quality of the seeds and the environmental conditions of the outside world will affect the seeds.seeds can germinate quickly, but if the conditions are not suitable, the healthy and full seeds are used in time, which will also inhibit the germination of the seeds.

The seed saving box makes the seeds sprout faster and better

The secret that allows seeds to germinate faster and better is that the seed preservation box can create a suitable environment and other environments by setting up different seeds to germinate, which meets its germination conditions and promotes its rapid germination.

The natural conditions of the outside world are unpredictable, and the temperature and humidity of temperature are also changing at all times. Therefore, there are many uncertain factors under natural conditions. There will be many uncertain factors. It is often not accurate to determine the germination rate of the seeds.The number of seeds to create the same constant environment is equivalent to putting these seeds on the same Running line and adopting the same training method. After a period of time, the seeds germinate well, and the seeds are fast. The seeds do not sprout.It is clear at a glance, which is more conducive to seed testing personnel to judge the quality of the seeds.

In fact, the seed preservation box is not only used in the seed germination rate, but also is often used in seed seedlings. In the natural environment, seed germination is often disturbed by adverse environmental factors, resulting in the seeds in the process of germination.Slow, and the quality of the plant after germination is not good, and let the seeds germinate in the seed saving box. Through simple configuration, it can create an ideal environment for it. Under the catalysis of these environments, the seed germination becomes more.Hurry up, the seedlings after germination are also more neat and robust, and then transplanted into the field. The survival rate is higher, which greatly improves the utilization rate of seeds and saves agricultural production costs.
