Sweet potato planting

planting technology

1. Soil

It is advisable to be deep, loose, well -drained, organic with more organic matter, and a certain Fertilizer.This kind of soil is loose, with good breathability, short -shaped shapes, neat, bright Skin, good food, high out of rate, and good storage resistance.

2. color

Seecn beds should be selected from the sun, high terrain, good drainage, convenient management, and fertile soil. It is best to be new seedlings. Old seedlings are often infected with dark spots and nematode diseases.Flink the seedlings of the seedlings once before planting potato, so that the soil grains are fine, the soil is loose, the farming layer is deep, and the chart is raised and raised.The seedlings are determined, generally no more than 6 meters.

3. Select planting

Select healthy potato species with this variety characteristics, distinctive Skin color, strong living power, moderate size (0.15-0.25 kg/piece), strictly eliminate the dark Skin color, cold damage, softened potato pieces, too much water loss, too much water loss, too much water loss, excessive water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water lossMore, and tetanus potato pieces with 70%methyltotobadin 300 times liquid before sowing for 10 minutes to disinfect, the effect is better.

4, density

Plant density varies from season, variety, use, etc.spring and summer potatoes are 3,000-5000 plants per mu, and autumn and winter potatoes are 4,000-6000 per acre.Strive for the leaf area index in the heyday of stems and leaves reached 3-4.5.Due to the continuous cutting of stems and leaves, the feed sweet potatoes can be encrypted to 6000-8000 plants per mu under the condition of multiple Fertilizers.

5. Temperature

The higher the temperature in the range of 16-35 C, the faster and more sprouts.16 C is the minimum temperature of the potato blocks, and the most suitable temperature range is 29-32 C.When the potato block is above 35 C for a long time, due to the great breathing intensity of the potato blocks, the consumption of nutrients, it is prone to "bran heart".When the temperature reaches above 40 C, it is prone to damage to hot and rotten potato.

Diseases and insect prevention

The main diseases of Sweet potato are Sweet potato black spots, Sweet potato stem neck disease, Sweet potato soft rot, potato plague, Sweet potato sore disease, Sweet potato vine disease, Sweet potato root wirling disease, Sweet potato rot, Sweet potato virus disease, Sweet potato purple patternYu Diseases and so on.The main pests of sweet potatoes include nasal insects, crickets, golden Turtles, ground tigers, and Sweet potato moth oblique night moths.The prevention and control of Sweet potato diseases and insect pests should adhere to the principles of preventing and comprehensive prevention.

Mainly controlling diseases and insect pests:

1. Choose a variety of disease resistance, pay attention to the disease quarantine of potato and seedlings.

2. Cultivate disease -free and strong seedlings, choose disease -free potatoes and seedlings from no library areas, or use decontamination seedlings.

3. Use a 50%bacterial or 50%methyltotobadin 500 times liquid to soak the Sweet potato vine for more than 2 minutes, and plant it after cooling.

4. Datian found that the diseased strain should be removed immediately and burned, and sprayed with a 50%fungus spirit 1000 times liquid. According to the situation, it can be sprayed once every 7 consecutive days until the root is eliminated.

5. Thoroughly clean up the diseased plants during harvest, pay attention to the rotation of water and drought, strengthen the management of water and Fertilizer, pay attention to drainage and ventilation, and appropriately appropriately appropriately apply plant ash and lime to make the plants grow strong and strengthen the disease resistance.

6. The main pest control of sweet potatoes can be used with pesticides such as the fear of enemy, killing pine, polyester pesticides, etc. According to the correct explanation, it is usually sprayed in the afternoon.

Potato planting

planting technology

1. Select the plot

The plot suitable for cultivating potatoes should be loose, good for soil, good permeability, rich organic matter, flat terrain, close to water, and convenient discharge irrigation.

2. Reasonable rotation

Potatoes should not be continuous, because the continuous work can increase the pests and pests of the soil, which can easily cause serious lack of certain elements in the soil. The natural balance of the soil microorganism is destroyed, the accumulation of harmful substances secreted by the root system will affect the yield and quality of potato.The previous crop can be rice, corn, green onion and garlic, melon, etc.

3. Reasonable fertilization

It is best to use balanced fertilization (formula fertilization).The Fertilizer of potato is fertilized. Tests have proved that when the tuber produced per mu is 1,000 kg, it is necessary to absorb 5.6 kg of nitrogen from the soil, 2.2 kg of phosphorus, and 10.2 kg of potassium.Potatoes need the most potassium for Fertilizer three elements, the secondary nitrogen, and less phosphorus.

yam planting

planting technology

1. Put the buds of yam seeds into the soil. The interval between lines and lines is about 1 meter, and about 10,000 pieces per acre of land are planted.

2. The growth process of plants such as yam needs to keep the surrounding environment high temperature and dryness, and do not like frost.About 35 days is enough to see Chang Miao.

3. Because the rhizomes of yam are relatively weak, they need to grow upward after emergence, otherwise it will easily wither.

4. Dorodes once a month for half a month, until about half of the shelf height, and then just remove the weeds.

5. Apply Fertilizer at the appropriate time and inhibit the growth of the ground. During the flowering period, fertilization can also be used to increase yield.

6. Properly increase some irrigation. Although yam is a drought environment, it is necessary to water in moderation in continuous drought weather. In the case of continuous heavy rain, it is necessary to drain it in time.

taro planting

planting technology

1. Temperature

taro requires high-temperature and humid environmental conditions. The bulb of the taro at 13-15 C began to germinate.The moderate growth temperature during the seedling period is 20 to 25 degrees, and the temperature growing temperature is 20 to 30 degrees.

2. Water

Whether it is a taro or a riru, it likes moist natural environment conditions.In particular, the leaf is strong and the period of the galvan stems is large. The amount of water requires a large amount of water.

3. Light

taro is more resistant to weak light, and the intensity of light is not very strict. The formation and expansion of the ball stems require short -day conditions.

4. Soil

taro is a happy crop, and its ball stem is formed in the underground soil layer. Therefore, it should be selected to be rich in loam or clay loam with rich organic matter and deep soil layers.

Cassava planting

planting technology

1. Origin environment

Edible cassava generally needs to be planted in areas with a frost -free period and an average annual temperature of 18 C and above.The origin environment of non -rigorous cultivation of cassava should meet the requirements of DB45/T410.

2. Selection and rectification

It should be selected to plant flat or mild sloped sand soil. For example, the planting site needs to be rotated by 2 years, 3 years, etc. The rotation crops are preferably crops such as peanuts, corn, soybeans and mung beans.The whole land is carried out in about one month before planting. Generally, it is two plows and two rakes. It is advisable to be a cultivated land depth of 30-40cm, making the soil flat and loose.3. Variety selection

The varieties of excellent characteristics such as low hydrocyanic acid content (below 100 mg/kg), high yield, high -yield, disease -resistant pests, and strong anti -inverse characteristics.my country mainly has a variety of cassava varieties such as Cutchota, South China No. 9, South China 6068, No. 12 South China, and GR891.

4. planting

The suitable planting time of cassava in my country is from February to April. It is advisable to choose the main stems of full maturity, 2-4cm of stem and diameter, dense section, stem Skin and buds, and disease-free pests. Stems, cut it into 15-20cm in length.The planting method can adopt four methods: flat, oblique insertion, and direct insertion and peaceful insertion. It is better to adopt a ridge covering membrane to plant or take a ridge dewdo plane.1M 0.8m is better.

Prevention and treatment of pests and insect pests

In my country, there are fewer cassava Diseases and diseases. Pests and insect pest control must adopt the principles of prevention -oriented and comprehensive prevention. agricultural prevention and control must be used to prohibit the use of pesticides and mixed preparations for the use of countries.When there is no large area of diseases and insect pests, the method of artificial removal should be used and destroyed in time;Secondly, measures such as weeding and soil cultivation can be created to create ecological conditions that are not conducive to the occurrence of pests and insect pests, but it is beneficial to or not hinder the growth of cassava growth.If the area of disease and insect pests is large, high -efficiency, low toxic, and low -residue pesticide varieties need to be selected for prevention and treatment.Cotenato grass damage is recommended to use artificial, machinery and cultivation techniques to prevent removal, such as ground film covering weeding technology, plowing Fertilizer and soil technology, and setting.

1. song Hongmei's breeding method

1. Soil

Pine red plums are not strict with soil, but it is best developed in minimide soil rich in humus, loose fat, and superior drainage.

2. humidity

Pine red plums are so humid and resistant to drought.Normally maintenance only needs to adhere to the soil wetness. Pay attention to drainage during the dry season to prevent soil watering.

3. Temperature

The pine red plum is so cool, humid, and sunny. The suitable development temperature is 18 C-25 C. In winter, it must be insisted on the temperature above -1 C.

4. Fertilization

During the growth period of Songhong Plum, apply a liquid fat Fertilizer every 1 to 2 months.

5. Light

song Hongmei is afraid of the low temperature and the sun, so in addition to summer, it must be placed in a shade or shade or a shade.In addition, in other seasons, the sun should be given enough.

Second, the precautions for breeding of song Hongmei

1. Pay attention to the number of water pour in winter, and stick to the soil slightly wet and dry. Do not be too moist.

2. Instant heat insulation in winter, which can be planted in small climate maintenance of the south side.

3. In terms of terrain selection, it is better to use high slopes and high -platform drainage and dredging gardens. Avoid high ground. It is best to choose indoor potted maintenance in the north winter.

4. When the soil is alkaline, it is improved by 5%sulfate solution, and the pH value is 6.5-7.0.

Third, the pruning method of pine plum

Trim in detail after flowering every year to achieve dwarfed tree crowns, maintain a beautiful tree -shaped shape, and can also promote the plant to germinate new flowering branches.When trimming, you need to pay attention. Except for some branches that affect the plant type, other branches should not be cut all, and half or three -quarters can be cut off.

1. Red Ruimu's water support method

1. After the autumn or early spring of the following year, cut the raw branches from the strong mother plant, and then 0.3 cm under the bud festival ~At 0.5 centimeters, cut the spike into a horseshoe -shaped cut, so that 2 to 3 buds can be kept at the upper part of the cuttings.After that, inserted water with water cups and placed in sufficient light.

2. Keep the cuttings of about 5 cm to 7 cm. Do not be too deep, and pay attention to change the water every 2 to 3 days to ensure the cleaning of the water quality.In this way, it can take root in about 30 days; if the water is changed, the water temperature can be increased and maintained at 20 C-25 C, and the rooting period can be greatly advanced.

3. Due to the internal differences between the individuals of the cuttings, the root of the cuttings is always different.To this end, when the new root root of the cuttings has extended 0.5 cm-1 cm, it is necessary to pick out the pot in time. Each pot can be planted with 3-5 plants to make it naturally cluster.scale.

Second, Red Ruimu's breeding method

1. Red Ruimu likes a warm growth environment and requires sufficient light.

2. Red Ruimu's requirements for temperature are relatively strict. The appropriate temperature for growth is between 22 C and 30 C. It can be cold -resistant, but in some places in the north, it will be frozen, which will cause death in severe cases.

3. Red Ruimu likes moist and fertile soil. Under the conditions of Smooth drainage and sufficient nutrients, growth will grow relatively quickly.

4. Some base Fertilizers should be applied before planting. After that, they must be picked up. They can apply rotten farmhouse Fertilizer or Organic fertilizer. They can also apply some compound Fertilizers according to their growth status.

5. Watering should be appropriate. According to the growth of Red Ruimu, you need to return green water in spring and seal frozen water in winter.Pay attention to drainage in the rainy season to avoid stagnant water and cause rotten roots.

6. During the growth process, Red Ruimu will have diseases such as leaf spots, powdery powder, and stem rot, as well as the harm of pests such as aphids, yellow thorn moths.Essence

3. When is it better to plant red Ruimu

Red Ruimu has the best living rate in spring and autumn, because Hong Ruimu likes the season with sufficient sunshine, and the sunshine in spring and autumn is not only sufficient, but also very gentle.The best survival rate for planting Red Ruimu in the season is the best.However, the specific planting season must also be determined according to the specific planting environment. For example, Red Ruimu can be planted in all seasons in the south, and try to avoid cold winter in the north.

1. Tea planting conditions

1. Soil

Generally, it does not contain lime stones with a thickness of up to 1 meter, and the sandy loam with good drainage is 1%-2%of the organic matter content. The permeability, water permeability or water storage performance is good. The pH value of pH is 4.5 ~ 6.5.

2. Rain amount

The average rainfall and the annual rainfall is more than 1,500 millimeters.Insufficient and excessive impact.

3. Sunshine

Light is the primary condition for the survival of the tea tree. It should not be too strong or too weak. It has special hobbies for ultraviolet rays.

4, temperature

One is the temperature, the other is the ground temperature, the average daily temperature needs to be 10 degrees; the minimum cannot be lower than -10 degrees.The average annual temperature is eighteen degrees to 25 degrees Celsius.

5. Terrain

The main terrain conditions include altitude, slope, and slope.With the rise of the altitude, the temperature and humidity have changed significantly. In a certain height mountain area, there are abundant rainfall, large clouds, large air humidity, and strong light.In more than 1000 meters, frost damage will be available.Generally, it is better to choose a south slope.The slope should not be too large, and generally requires below 30 degrees.

2. Points of tea planting

1. Soil

If you want to plant high -quality tea, the choice of the plantation place is the foundation.Generally, the soil of the planting place should be calculated from four to 5 to 6.5, which is a sore soil.Secondly, the soil structure of the planting site should be complete, the soil layer is deep, the soil fertility must be sufficient, and the organic matter content is abundant.Finally, the rich water source, water quality and soil must not pollute, convenient irrigation, convenient transportation and water and electricity, and the soil is red or yellow soil.

2. Water

The growth of tea trees is also relatively high in water, so we need to plan drainage and irrigation systems in advance.According to the terrain of tea planting, the layout is reasonably, and the arrangements such as roads, ditch, water pipes, and faucet are carefully done.The irrigation system of the tea garden is generally sprayed, which can not only save water resources, but also spraying irrigation methods is more conducive to the growth of tea.During the growth of tea, we need to irrigate frequently, but the amount of irrigation must not be very large, and the surface soil can have a certain humidity.

3. Nutrition

In order to promote the growth and renewal of tea, we need to properly top topical pursuit.The ribbon branches that are just planted for a long time need to be applied once in the spring, and the tea trees from two to three years need to increase the amount of topdressing, which is doubled in one year. Of courseNitrogen Fertilizer.Three years later, tea trees need to be picked up four times a year, including base Fertilizer, spring Fertilizer, autumn Fertilizer, winter Fertilizer, and leaf surface Fertilizer.

4, density

The density of tea planting is also a problem that we need to pay attention to when planting.Reasonable planting density is good for the yield and quality of tea.If the density of planting is too high, it is easy to occur in various problems such as dysplasia and uneven light.Then the spacing of the density of planting is about two meters and one meter between the plants.

5. Anti -frozen

We all know that the cold resistance of tea trees is very strong and will not die in heavy snowy weather, but this disease does not mean that it is not afraid of freezing.Pay attention to the treatment of cold and insulation during the young tree, otherwise it is also easy to be frostbite, which will affect the yield and quality after the tea tree.Then when the cold wave comes, we put some insulation materials around the tea trees, such as straw, which can have a good effect of preventing cold.

6. Pruning

Pouring tea trees is a very necessary job to grow tea.The tea gardens we see are basically consistent with the tree shape of tea trees, so as long as we prunites, we can keep them consistent, and only when trimming like this can the quality of tea growing tea leaves will be better.When necessary, we need to update the trees, that is, comprehensively update the tea trees to improve the quality and yield of tea.

3. Prevention and control of tea diseases and insect pests

1. agricultural prevention and control

Choose a variety of disease -resistant insects and enrich plants

Different varieties of tea have different morphological structures and biochemical components, so different varieties of tea are very different from the resistance of different diseases and insect pests.When planting tea trees, we should select good diseases and insects according to the specific situation of the local area to reduce the harm of pests and pests to the tea trees.

Tour and clean up the tea garden

Properly trimming the tea tree can not only regulate the trees, promote the increase in picking area, but also effectively reduce the occurrence of pests and insect pests.

Reasonable fertilization and picking in batches

The fertilization of the tea garden should be determined according to the results of the meter measurement to prevent the amount of fertilization, avoiding a large amount of nitrogen fertilizer caused by the weakening of the plant resistance.In addition to applying phosphorus and Potassium fertilizer, trace elements and organic Fertilizers should also be supplemented in an appropriate amount to reduce pests and insect pests.

2. Biological control

Treaty of the enemy

The natural enemy resources in the tea garden are relatively abundant. For example, bare -eye bees can control the density of pests such as cypress, scrusted winged, and wings.The control of natural enemies to control pests should be used to ensure the biodiversity in the tea garden as much as possible and ensure the living environment of natural enemies.

Bacterial prevention and treatment of diseases and insect pests

Bacteria are used in tea diseases and insect pests.Su Yunjin Bacillus can secrete a toxin. This toxin only infects some types of pests, and has no toxic effect on natural enemy insects and humans. The bacteria agent can be used in the tea garden to effectively prevent the occurrence of lumper -winged pests.Essence

fungal prevention and treatment of diseases and insect pests

The fungal biological pesticides in the prevention and treatment of tea diseases and insect pests mainly include white stalemate and wooden mold.

After contacting the pests, the spores of the White Strike can invade their mycelium into the body of the pest. In tea applications, pests such as tea poisoning moths and tea roll moths are well preventive.

Woodwood bacteria secrete antibacterial protein and other substances to inhibit the infection of tea leaves by pathogenic bacteria. At the same time, they can also inhibit the reproduction of pathogenic bacteria through spatial and nutrient competition.

3. Physical prevention

There are two types of physical control methods commonly used in tea gardens.

Artificial killing is a killing of pests in the tea garden in accordance with the growth law and characteristics of pests.

The deduction of appliances is based on the trend of pests, and the use of physical factors such as magnetic fields, odors, temperatures, or the color of the appliance generated by the appliances to induce killing insects, thereby reducing the density of pest density.
