Winter free paddy field no-tillage live rapeseed
No-tillage seedlings in winter in paddy field, every 667 square meters (1 acre) than the nursery transplants to reduce labor 5-6, save 60-70 yuan investment, cost-effectiveness of 100-150 yuan, but also staggered busy season, labor , Save money, easy to operate, increase production efficiency, has important promotion value. First, the selection of fine varieties: should use high quality, high yield, high resistance hybrid double low or conventional double low rapeseed varieties. II. Careful sowing and regrowth: One night rice field is planted in the middle and early October after harvest, and the second night rice field is planted 9-12 days before harvest. Paddy fields should be drained 3 to 5 days before sowing. 2 to 4 days before sowing of drought in paddy fields should be filled with horse water. The planting capacity of 667 square meters is 300-500 grams. When sowing seeds, first 15-20 kg of fine soil plus 6-7 kilograms of phosphate fertilizer or 50 kilograms of ash and 6-7 kilograms of phosphate fertilizer mix well and spread directly and evenly. After harvesting, or after harvesting two nights, the waist, the circumference, and the ditches should be excavated manually or with a trencher. The width of the groove should be 30 cm, and the width should be 1.1-1.2 m. Then, the ditches should be shattered and covered or covered. In the middle of the hustle and bustle. Third, carefully between the seedlings, Dingmiao: Spleen should be reserved to stay thin, pull sick, weak, hybrid seedlings. The first time the seedlings were carried out after the seedlings and the second seedlings were carried out when the second true leaf was grown. Rape grows to 3-4 leaves when the true seedlings, generally 667 square meters Dingmiao 2 - 230,000. After one night of field Dingmiao, 667 square meters with 15% paclobutrazol wettable powder 50 grams of water 50-60 kg spray once to prevent tall seedlings. In the second late field, the hypocotyl over-stretching of rapeseed during the symbiosis between rice and rapeseed caused the problem of seedling growth. It is important to carry out chemical control treatment. The method of chemical control treatment is: using 5% uniconazole 1 package (10 grams) to add 10 kilograms of water, 8 kilograms of oilseed rape seeds can be soaked, and soaking for 7-8 hours before dressing and sowing. Fourth, scientific fertilization: one night field before sowing, two nights after the harvest of rice in every 667 square meters spread rotting pigs, cattle manure 1200-1500 kilograms, or 1500-2000 kilograms of soil-fertilizer, or splash on the water 1700-2000 kilograms of cooked pigs and cows' urine, another 15-20 kilograms of compound fertilizer plus 1 kilogram of borax. When 3-4 leaves of rape are planted, 667 square meters should be topdressed with 6-7 kg of urea when it rains. After 667 m2 of spring, 5 kg of urea and potassium chloride were topdressed. Buds and flowering time should be sprayed once each 125 grams of borax 50 ~ 60 kg of water, once with spray Shi Bao; spraying the primary potassium dihydrogen phosphate 100 grams of water 50-60 kg. Fifth, pay attention to chemical weeding: After a field of rape planted cover soil, 667 square meters of acetochlor 80 grams of water evenly sprayed on the surface. Rape 3-4 leaves, 667 square meters to use 10.8% high efficiency canopy can be 20-30 ml of water spray 20-30 kg of weeding. Sixth, integrated pest control: 1, and other winter crop rotation. 2. The same variety is planted in the same area for no more than 3 years. 3. Drain the drain in time to reduce the humidity in the field. 4. Spray 50% carbendazim or sclerotium net 100 grams water 50 kilograms each at the convulsing stage, early flowering stage, full flowering stage, and podning stage. 5, control locusts, etc. with high efficiency and low toxicity or non-toxic agricultural Meng special, anti-salty and other pesticides.
