Listed rape cultivation in the Spring Festival
Rape growth period is short, 40 days -50 days, easier to cultivate and manage. The dishes made of rapeseed are crispy and refreshing, delicious and fragrant. They also have the therapeutic value of illnesses and physical strength. They have curative effects on stoppage of souring blood, swelling and pain, discomfort, blood stasis, blood stasis and other diseases. The tender, green, and shiny "little" rapeseed has become an indispensable vegetable good for urban and rural residents during the New Year holiday. Cheng Shibin, a graduate student of Agricultural Broadcasting School in Shanting District of Zaozhuang City, planted 400 square meters of facility rape in the winter of 2002, and was listed before and after the Spring Festival, earning more than 3,000 yuan. The best cultivation techniques for oilseed rape introduced during the Spring Festival are described as follows: Variety Selection Varieties should be selected for strong winter, cold-tolerant, storage-resistant, disease-resistant, high-yielding green canola, Nannong dwarf yellow, April slow and May slow Excellent varieties. Cultivating strong seedlings The rapeseeds that are listed during the Spring Festival are mostly pre- and post-crop crops in the greenhouse, or fast-growing leaf crops grown intercropping. Therefore, seedlings must be transplanted. The best sowing period is: 70 days before the Spring Festival - 85 days, that is, in the middle of November. Seeds can be soaked in water at 25°C for 3 hours to 4 hours and germinated at 20°C for 24 hours. The seedbed is applied with 12 kg 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 g-20 g per square meter, seed coating 1 cm, covering Straw moisturizing, 1 square meter seedbed can be planted 50 square meters Daejeon. After sowing, keep warm, maintain 20°C—25°C, reduce to 15°C—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 case of time and seedlings, it is generally possible to pass the secondary seedlings, so that the seedling distance is maintained at about 4 cm, 30 days to 40 days after sowing, and seedlings 3 to 4 leaves when planting. Transplanting generally uses 5,000 kg of composted manure per 667 square meters, followed by 30 kg of diammonium phosphate, then deep tillage, flattening 1 meter wide, opening 5 rows of small ditch, planting seedlings at a spacing of 10 cm, and every 667 square meters Rice planted 35000 plants. The depth of planting is appropriate to be buried in the base of the first true leaf petiole. After the plant is completed, it is watered immediately, and the amount of water cannot be too large. After the seedlings are cultivated, the seedlings are slowly cultivated and the seedlings are allowed to be properly ventilated. The daytime temperature is maintained at about 20°C and the nighttime is about 6°C to 10°C. Choosing cultivator 1 to 2 times on sunny days, after the plants have begun to grow new leaves, apply 15 to 20 kg of ammonium sulfate or 10 to 15 kg of ammonium nitrate per 667 square meters, spread the fertilizer, and then water it. 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, a long period of rain and snow often occurs. 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 a cloudy day, if the sunlight is too strong, it can easily cause wilting in rapeseed. When wilting is found, part of the straw curtains should be immediately covered to form a flower yin. After the rape returns to normal, all the veils will be uncovered. If you find locusts, spray them in time. Can be used 20% of the speed of killing 2500 times or 2,5% fluoxazole 1800 times spray control of aphids. About 40 days after harvesting, harvesting can be started, and the harvesting or harvesting can be performed in several batches. China Agricultural Network Editor
