Efficient cultivation technology of spring soybean

The planting of green young soybeans is simple, the province is labor-saving, and the efficiency is high. It is generally feasible to grow in the rice area. Green soy beans have "May tree", "June tree", generally produce 500 to 700 kilograms of fresh soybean meal, mu benefits 600 to 800 yuan. 1. Variety selection: Choose high-quality hybrids with early maturation, high yield, and strong cold resistance, such as "Heifeng", "901", "8157" and other varieties. 2. Ditching and sloping: In the past years, the supporting trench system was opened in the field, with a width of 1.1 to 1.2 meters and a width of 0.2 meters. 7 to 10 days prior to sowing, put more than 1500 kg of decomposed organic fertilizer (organic fertilizer before ploughing and turning on the field), 40-50 kg of high-concentration compound fertilizer, keep the ditch open, and use 5 to 7 days before sowing. Oxalamine phosphorus kills field weeds. 3, timely sowing: Seed treatment before sowing can be used Fumei double dressing disinfection, the amount of the seed weight of 0.2%. In mid-to late March, when the temperature is stable at more than 10 degrees, select good weather to acupuncture at the acupuncture point, generally spaced 30 to 35cm, plant spacing 15 to 20cm, 0.8 to 0.9 million per mu basic hole, 3 to 4 per hole, and acres to sow About 6 to 8 kg. Immediately after sowing, it was covered with a plastic film and the mud was sealed. 4. Fertilizer input: (1) Early application of Miaofei. Mulching fields can be implemented Miao Fei basis, generally about 8 to 10 kg of urea per acre, in April on the middle of the film in time to release seedlings. The open field cultivation in Miao after Mushi urea 10 to 15 kg. (2) Fertilizer is applied to the end. At the beginning of flowering, Mushi acquaintances, animal urine 500 to 700 kilograms or available nitrogen fertilizer 15 to 20 kilograms, while increasing phosphorus and potassium fertilizer. Fertilization can be combined with a cultivator to promote root growth. (3) foliar spray fertilizer. It is usually sprayed 2 or 3 times in succession. It takes 8 to 10 days apart from the beginning of the flowering period to effectively reduce the loss of calyx, accelerate the expansion of the beans and increase the yield. The general fertilizer category is potassium dihydrogen phosphate 500 times, 0.01-0.05% ammonium molybdate aqueous solution, and 2-3% superphosphate calcium leaching solution. 5, water management. Reducing soil moisture at seedling stage can increase soil temperature and facilitate growth. The lack of water in the flowering and poding season will cause a large number of flowers and pods to fall off. It should be timely flooded and drought-resistant. The grouting granules encounter droughts, which will increase pods and pods and must be filled with water. 6, disease prevention and pest control. The prevention and control of downy mildew in the early stage, and the prevention and control of migratory locusts in the wheat field in the later period, and the use of methamidophos, dichlorvos and other highly toxic pesticides are strictly prohibited. 7, timely picking. In the first half of June, timely picking of green oysters will be marketed and the rice will be sown in time. China Agricultural Network Editor
