Soybeans can fertilize their fertility, their short growing season, wide marketability, and fast growth. Spring soybeans should be planted in six key ways: First, seed treatment to increase the germination potential. Before sowing, select seeds full of seeds for drying, in order to increase the growth potential of the seeds. When sowing, use ammonium molybdate 0.1%—0.2% or rhizobia (0.5 kg of fungus mixed with 10 kg of seeds) for seed dressing. According to experiments, after seed treatment, nodule formation was early and many, rapid growth, early branches, seed setting rate and sorghum number increased, and production increased by 10% to 20%. Second, fine soil preparation, adequate base fertilizer. Deep plowing 20-25 cm, crushed back and forth from the turtle back ridge 1.2 meters (paddy field), dry slopes can be wider to prevent the accumulation of water rot. Early in the three-leaf period, soybeans require potassium and phosphate fertilizers in particular. Therefore, 1500 kg of miscellaneous fertilizer should be applied to Mushi, 600 kg of fire and soil ash or plant ash, 10 kg of phosphate fertilizer, and 20 kg of compound fertilizer. Mix well and make the base fertilizer, and then open the hole to plant seeds. . The spacing is 16-18 cm, the spacing is 12-14 cm, the holes are sown in 1-2 capsules, and the mu plants are 28-30 thousand. Third, use autumn seed to ensure a full seedling. In spring sowing, it often encounters low temperature and rainy weather, which causes bad seeds to affect the whole seedlings. With the high germination rate, strong growth potential, ability to preserve seedlings, and early maturation, it is the key to seizing high and stable yields. Suitable varieties planted in paddy fields are "Guangdong No.1" and "Gudoudou No.2". Good varieties suitable for planting in the red soil hills include "Maohuanghuang", "Dajinhuang" and "Yuedou No.1". The above-mentioned improved varieties have the characteristics of compactness, dwarfness, and drought tolerance (wetness). Early sowing can increase the yield during the vegetative period. Soybeans are more resistant to hypothermia. Generally, the temperature is stable at 10°C (from spring to rain), which is suitable for sowing. This period is conducive to the promotion of more shoots and higher yields. Fourth, early as early as cultivator top dressing, promote the growth of anti-reverse and promote production. 1. Soybeans are hi-tillage crops. Seedlings grow slowly and prone to weeds. When the height of seedlings is 15-20 cm, cultivating and weeding should be carried out in order to promote the development of rhizobial bacteria and to prevent lodging on the cotyledon nodes. In the intercropping, 50-60 kilograms of lime powder are used per mu, which can increase resistance to pests, lodging, and increase grain weight. 2. At the beginning of the branching period, 5 kg of urea and 7 kg of potassium chloride were applied, combined with the second cultivating, to increase the number of effective litchi plants and increase the rate of flowering. 3. In the closure of the line to promote dwarfism, acres of paclobutrazol 0.7 grams of water 25 kg, can promote dwarfing and increase the number of knots per plant. 4. During the flowering stage, spraying plant-planting hormone and potassium dihydrogen phosphate 1-2 times, the seed setting rate can be increased by more than 20%. Fifth, Qiao spray inhibitors, topping the heart and increase production. In the flowering period, using sodium sulfite 4-5g to water 50kg, once a week, even spraying 2-3 times, can increase the photorespiration intensity of soybean, reduce the consumption of photosynthesis products, increase the accumulation of dry matter and the output reaches 8%-10%. Topping the heart, removing the top 20 days before harvest can increase the seed-setting rate by 7%-8%. Sixth, prevention and treatment of pests, plant protection and conservation benefits. In the early stage, there were locusts, ground tigers, and fruitworms. In the medium term, there were soybean pods, eight-star floating worms, and leaf spot diseases. In order to harm young leaves, spikes, and eat pods, pesticides should be selected for timely prevention and control.
