The planting method and time of oilseed lettuce, the planting time and method of oilseed lettuce

Due to the development of cultivation technology,Oily lettuceIt can be said that planting can be done all year round, but the best time to sow is generally from early April to mid-July.

1. Select land for ploughing

Oilseed wheat rape can be planted all year round, strong adaptability to the soil and the environment, choose a deep soil layer, fertile, convenient drainage and irrigation plots, deep ploughing about 20 cm, increase the air permeability of the soil, after exposure to disinfection, apply the rotten farmhouse fertilizer, fully mixed and then leveled and raked.

2. Sow seeds and raise seedlings

Watering enough water before sowing to keep the soil moist, select high-quality seeds to soak, sow seeds by sowing, cover 1-2 cm of dry soil, and cover plastic film when the temperature is low, which plays the role of heat preservation and moisturizing, and promotes the germination of seeds as soon as possible.

3. Colonization density

After the rape seedlings grow, the film should be removed, wait for 6 days, dig the planting hole according to the 20x15 cm plant spacing, and carry out the transplanting value, it is best to choose the sunny day after the rain or the evening of the sunny day when transplanting, and check the seedlings after planting to fill the gaps, and cultivate strong seedlings.

4. Water and fertilizer management

During the growth of oilseed rape, it is necessary to top dressing in time, the first fertilization is carried out after transplanting and planting, when the seedlings grow to 20 cm, the second top dressing is carried out with diluted phosphorus and potassium fertilizer, and 15-20 days before harvesting, with diluted urea.

Carry out the final growth, and water in time after fertilization to ensure that the soil is moist.

Precautions related to the cultivation of oilseed lettuce

Rapeseed seeds will generally germinate after about 5-7 days, if you want to speed up the germination rate of rapeseed, you can germinate the seeds before planting.

You can first soak the seeds of oilseed lettuce in warm water at 40-45 for a period of time, and then put the seeds in a cool place, and wait for the seeds of oilseed lettuce to show white before planting.

If you want to speed up the growth rate of oilseed lettuce, you can also control the ambient temperature between 20-25, and then open the window every morning and evening for ventilation, which can promote the growth of oilseed lettuce.

Method and time of cultivation of oilseed lettuce

2. Soil: Choose loose, fertile, breathable, and slightly acidic soil with good drainage.

3. Seed selection: Select healthy and full rape seeds, soak them in warm water for 8 12 hours, remove them and wrap them in a damp cloth and put them in the refrigerator for germination.

4. Planting: Plant the treated seeds into the soil, cover with a thin layer of soil, and water them appropriately.

Oilseed lettuce maintenance

Oilseed wheat rape likes moisture, during the breeding period should maintain the moisture of the soil, to provide it with sufficient water, before planting, the decomposed organic fertilizer is evenly sprinkled in the soil, and then turned and stirred, so that the nutrients in the soil can be fully volatilized.

Oilseed lettuce likes light, needs sufficient sunlight during the breeding period, but is not suitable for strong direct light, too strong light will cause sunburn to its stems and leaves, when the light is strong in summer, appropriate shading measures need to be taken.

Oily wheat rape growth period to give enough water to the seedlings, generally speaking, watering 1 time a day, if the soil fertility is not enough, can be applied a microbial agent vegetable and fruit fertilizer, in the rainstorm, to remove the water in the soil in time.

1. Sowing time.

The normal planting time is between mid-to-late April and mid-May.

August-September. If it is planted in winter, it is generally cultivated in greenhouses.

2. Soak seeds to promote germination.

Soak the seeds in water for 5 hours and then drain them before germination, because the seeds are small, you can soak the seeds without hot water. Germination can be treated with clean wet sand layering. Layer 20 cm of sand, put the seeds and cover with another 2 to 3 cm of sand.

Add ice cubes and water to the thermos flask and put the seeds to germinate, and change the water once a day. Or wrap the seeds in a damp cloth and rinse them once a day in a 15 to 20 degree incubator.

3. Sowing seedlings.

Live broadcast in the seedbed, the seedbed is evenly sown, or the row of ditch sowing, the same must be evenly sown, so as to facilitate the seedlings. Sowing and covering soil 1 cm, after germination, the soil covering is shallower than that of direct seeding, which is convenient for germination. If the temperature is good in spring and autumn, you can not protect the seedlings, but you can also raise seedlings in greenhouses, and the seedlings in greenhouses are relatively fast.

Young shoots need to be moisturized, but to reduce direct sunlight, seedlings can be raised in shade.

4. Seedling management.

It is best to water it every morning and evening, but the amount of water is not too much, and the spray is better, so that the seedling leaves can quickly absorb water. However, it does not cause water accumulation. After emergence, leafy vegetables are prone to soft rot, downy mildew, cataplexy and other diseases.

Reducing humidity, sprinkling rice husks can absorb moisture and prevent diseases. However, it is necessary to pull out the diseased strain first, and then spray carbendazim and other agents to eliminate the disease.

Harvesting of oilseed lettuce:

Harvesting begins about a month after planting, or from about 15 leaves, usually in the morning, when the fully grown, thick, brittle green leaves are broken off by hand. After harvesting, after the wound is dried, 1 time of decaying organic fertilizer can be applied to promote the germination of new leaves, and it can be harvested again after a period of time.

The harvesting standard of oilseed rape is relatively relaxed, 14-16 leaves can be harvested, and the harvest can be carried out according to market demand, avoiding too early or too late, otherwise the yield and quality will not be too high.

The planting method of rapeseed is from germination, sowing and seedling raising, seedling thinning, seedling management, etc., and the planting time of rapeseed is from mid to late April in spring, mid-to-late May in summer, August in summer and September in autumn.

First, the planting method of oilseed lettuce.

Germination: Oilseed rape seeds are soaked in warm water for about 60 hours for half an hour to sterilize, then soaked in water for 3 hours, and then wrapped in wet wipes, and placed in a place with a temperature of about 25 to promote germination, do not put it in the sun, and prepare for sowing when the seeds germinate 70%.

Sowing seedlings: the seedbed of rape is wide in rice, the ternary compound fertilizer is applied as the base fertilizer, the seedbed is leveled, watered thoroughly and ready for sowing, the rape seeds and sieved fine soil are stirred evenly and sprinkled into the seedbed. After the seeds are evenly sprinkled, cover with fine soil 1 cm thick, and then cover with mulch, felt and rain cloth.

Wait for more than half of the seeds to be unearthed, and uncover the mulch.

Seedlings: Seedlings are seedlings twice during the seedling period, and the distance between the seedlings is 3 cm. 75 kg of nitrogen, phosphorus and potassium compound fertilizer was applied per mu for rape preparation, and flat furrow planting was selected. The plant spacing of the lettuce is 15-20 cm, the row spacing is 20 cm, and it is watered once after planting.

Seedling management: water the seedlings once after 5 days, and there is no need to squat the seedlings. Oilseed lettuce needs a lot of water, and it should be watered once every 3-5 days, so that oilseed lettuce can not be short of water.

During the growth period of oilseed wheat rape, urea was sprinkled with water 2-3 times, 10 kg each time, and potassium dihydrogen phosphate was sprayed with foliar fertilizer 2-3 times. Oilseed lettuce should be harvested as early as possible, and the leaves are easy to get old when harvested late.

Second, the planting time of oilseed and wheat rape.

The planting time is generally from mid to late April to mid-May in spring, August in summer, and September in autumn. In winter, it is cold, so if you want to grow oilseed and wheat vegetables, try to choose greenhouse planting.

How to downy mildew from oily wheat cabbage**

1. Seed dressing. When sowing oilseed lettuce, use methyl frost liquid wettable powder with 20% seed quality active ingredient to dress seeds, or when seedlings grow 2-4 true leaves, regardless of whether downy mildew occurs, frost urea and manganese zinc are used for control.

2. Clear the field for disinfection.

Every year, after harvesting or before planting, it is necessary to remove diseases and insects and fallen leaves and fruits in the field in time. It can be taken out of the field in a concentrated manner, which can be burned, or it can be sterilized by high-temperature fermentation to make it manure. If it is planted in a greenhouse, the aisles, furrows, shelves and ear rooms in the greenhouse should be disinfected.

Do a comprehensive and uniform disinfection method of keto cultivation can generally be disinfected with ozone disinfection and fumigation to eliminate germs, destroy their wintering sites, and reduce the base number of pathogens in the field.

3. Strengthen management.

Do not transplant too late with Sencha to avoid too large seedling age. It is mainly cultivated with high furrows and high ridges, and cannot be planted too densely. The temperature difference in the greenhouse should be controlled, the humidity should be properly reduced and the light should be increased.

When watering, it is necessary to water more and a small amount, not flood irrigation, and it is best to be able to drip irrigation. At the same time, the amount of nitrogen fertilizer should be strictly controlled, and nitrogen fertilizer should not be applied excessively to avoid fertilizer damage, resulting in plant growth, and phosphorus and potassium fertilizer should be appropriately applied.

Dear, I'm glad to answer for you, the planting time of rape is generally from mid to late April to mid-May in spring, August in summer and September in autumn. Before planting, the land is watered and then sown, and then a layer of farmhouse manure is sprinkled on the digging hall, covered with a layer of film to promote germination, when 80% of the young shoots are grown, the film will be uncovered for planting, and finally only need to do a good job of ethnic scatter or water fertilizer and pest control.

Due to the development of planting technology, it can be planted all year round, but the better sowing period is generally from early April to mid-July。Planting methods of oilseed lettuce:1

Oily wheat vegetables can be grown all year round and are highly adaptable to the soil and the environment. Choose a plot with deep and fertile soil layer and convenient drainage and irrigation, and deepen the depth of about 20 cm to increase the air permeability of the soil. After drying and disinfection, apply well-rotted farmhouse fertilizer, mix well, and level the rake.

2.Before sowing seedlings, water enough to keep the soil moist. After soaking the high-quality seeds, sowing them is sown and covered with 1-2 cm on dry soil.

When the temperature is low, it is necessary to cover it with plastic film to keep warm and moisturize to promote the germination of seeds as soon as possible. 3.After the planting density seedlings grow, the film should be removed, wait for 6 days, dig the planting hole according to the rigid planting distance of 20x15, and set the transplanting value.

When transplanting, it is best to choose a sunny day after rain or a sunny evening. After planting, check the seedlings to fill the gaps and cultivate strong seedlings. 4.

The water and fertilizer pipe should be prepared for the top dressing of oil and wheat vegetables in time during the growth period, and the first fertilization should be carried out after transplanting and planting. When the seedlings grow to 20 cm, a second top dressing is performed with diluted phosphorus and potassium fertilizer, and the last growth is promoted with diluted urea 15-20 days before harvest. After fertilization, it is necessary to water in time to ensure soil moisture.

Matters that should be paid attention to when planting oilseed lettuce: It generally takes about 5-7 days for the seeds to germinate and unearth. If you want to speed up the germination of seeds, you can speed up the germination of seeds before sowing. First, you can soak the seeds in warm water at 40-45 for a while, then put the seeds in a cool place, and wait until the seeds of the lettuce turn white.

If you want to speed up the growth of oilseed lettuce, you can also control the ambient temperature between 20-25, and then open the window for ventilation every morning and evening, which can promote the growth of oilseed lettuce.

Cultivation techniques. 1. Choose the best species.

Heat-resistant, disease-resistant, high-quality and high-yield varieties should be selected, such as sesame oil wheat green.

2. Sow seeds at the right time.

Summer-sown organic oil wheat rape is suitable for sowing from late June to early July, 50 grams of seeds per mu need to be sown, seedling age is 25 30 days, and planting is from late July to early August. Autumn sowing is suitable for sowing from the end of July to the beginning of August, and 40 50 grams per mu need to be sown.

3. Seed treatment.

Due to the high temperature, drought and rainy season in the seedling raising period of summer and autumn stubble wheat rape, in order to protect the seedlings and seedlings, it is best to take soaking and germination before sowing. First, wrap the seeds in gauze and soak them in cold water for about 1 hour, then pick them up and put them under 15 20 conditions to germinate, and sow them after the seeds are white in 2 3 days.

4. Cultivation management.

Plots with higher terrain, fertile soil, good permeability, and no Asteraceae crops should be selected. Apply sufficient base fertilizer, 5000 kg of high-quality manure or 200 300 kg of plant ash per mu.

After sowing, a small arch shed should be built with 2 meters or 4 meters of bamboo pieces on the seedbed furrow, and then covered with a layer of shade net or old film on the arch shed to prevent rain and cool down. Throughout the growth and development period, keep the field moist and the soil loose.

5. Harvest at the right time.

When the number of leaves reaches 30 34 and the plant height is 45 48 cm, the one-time harvest is carried out at 2 3 cm above the ground**.
