Rapeseed has a short growth period, and it can be cultivated in 40-50 days. Dishes made of rapeseed are not only refreshing and refreshing, but also have therapeutic value for illness and health. They can treat swelling, discomfort, and blood stasis. The best cultivation techniques for oilseed rape introduced during the Spring Festival are described as follows: The varieties should be selected for the "green rape", "Nannon dwarf yellow" and "April slow" for strong overwintering, cold resistance, storage, disease resistance and high yield. And "May slow" and other fine varieties. Cultivating strong seedlings The rapeseeds that are listed during the Spring Festival are mostly intercropping and fast-growing leafy vegetables, which must be transplanted. The best sowing date is mid-late November. First soak the seeds in water at 25°C for 3-4 hours and then germinate at 20°C for 24 hours to germinate. 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 plough is tilled and leveled, watered to sow, 15-20 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 kept at 20-25°C, and it decreased to 15-20°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 addition, the seedlings should be kept at a distance of about 4 cm and seedlings should be planted at 3-4 leaves 30-40 days after sowing. Twice transplanting generally applies 5000 kilograms of cooked manure per acre, then add 30 kg of diammonium phosphate, then deep plowing, flattening 1 meter wide, open 5 rows of small ditch, planting seedlings at a spacing of 10 cm, 3.5 plants per acre. 10,000 plants. The depth of planting is appropriate for burying in the base of the first true leaf petiole, and watering immediately after the planting is completed. The amount of water should not be too large. After the easing of seedlings, the seedlings are treated with easing seedlings, and the seedlings are allowed to be properly ventilated. The phlegm temperature is maintained at about 20° C. during the day and 6-10° C. at night. Sunny cultivating 1-2 times. After the plants began to grow new leaves, 15-20 kilograms of ammonium sulfate or 10-15 kilograms of ammonium nitrate was applied per acre and watered immediately. When the base fertilizer is insufficient, it can be top-dressed in advance. In the winter, the cold current is relatively frequent, especially before the Spring Festival. Longer rain and snow conditions often occur. When there is cloudy weather for several consecutive days, the light is weak and photosynthesis cannot be carried out properly. 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 aphids are found, they can be sprayed with 20% of fast kill 2500-fold or 2.5% of fleas 1800-fold. About 40 days after harvesting, the plants can be harvested, and then harvested or harvested in several divisions. China Agricultural Network Editor
