Variety selection: Good varieties should be selected for strong overwintering, cold-resistance, storage-resistant, disease-resistant, high-yield green canola, Nannong dwarf yellow, April slow and May slow. Cultivate strong seedlings: Early spring oilseed rape is mostly fast-growing leaf crops intercropped and must be transplanted. The seeds were first soaked in water at 25°C for 3 to 4 hours, and then germinated at 20°C for 24 hours to sprout. The seedbed is applied with 12 kilograms of high-quality rotting organic fertilizer per square meter, and then a small amount of ternary compound fertilizer is added. The cultivating is done by ploughing and leveling, watering sowing, 15 to 20 grams of seeds can be sprinkled per square meter, and the cover soil is 1 centimeter thick. Cover straw grass moisturizing. After sowing, the temperature was maintained at 20°C to 25°C, and it decreased to 15°C to 20°C after emergence and 10°C at night. Although rape is more cold-resistant, the temperature should not be too low to prevent premature bolting. The seedlings can be sprinkled with a layer of finely grounded soil when there is no dew. In order to reach the time of seedlings, the seedling distance should be maintained at about 4 cm. After seedlings grow 30 to 40 days, 3 to 4 leaves grow. Twisting and transplanting: Generally, 5000 kg of cooked manure is applied per acre, and then 30 kg of diammonium phosphate is added. Then deep plowing is done. The width is 1 meter, and 5 rows of small ditch are opened. The seedlings are planted at a planting distance of 10 cm. Each acre is planted. 35,000 plants. Planting depth to bury the first true leaf, the base of the petiole is appropriate, watering immediately after the completion of a planting, the amount of water can not be too large. Management after easing seedlings: After easing the seedlings, the seedlings are irrigated with water, and appropriate ventilation is provided. The phlegm temperature is maintained at around 20°C during the day and 6°C to 10°C during the night. Sunny cultivating 1 or 2 times. After the plants began to grow new leaves, 15 to 20 kilograms of ammonium sulfate or 10 to 15 kilograms of ammonium nitrate was applied per acre, and they were then watered. When the base fertilizer is insufficient, it can be top-dressed in advance. In the early spring, when there are days of cloudy snow weather, the light is weak, and photosynthesis cannot be carried out normally. The temperature should be reduced appropriately to minimize the respiratory consumption, and special attention should be paid to uncovering the straw curtain. On the first sunny day after the cloudy day, if the sunlight is too strong, the rape can be wilted. At this time, some straw curtains should be covered immediately. After the rape is returned to normal, all the straw curtains will be uncovered. If locusts are found, they can be sprayed with 20% speeding 2500 times or 2.5% fluoxetane 1800 times.
