High yield of spring soybeans

Seed treatment, to increase the germination potential before the selection of seeds full of seeds for drying to increase growth potential, sowing with 0.1% to 0.2% ammonium molybdate or rhizobia (0.5 kg bacteria mixed 10 kg seeds) 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%. Fine soil preparation, adequate basal fertilizer deep plowing 20 to 25 centimeters, repeated smashing after the turtle back ridge ridge 1.2 meters (paddy field), dry sloping land 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 use of good seedlings in autumn to ensure that when a seedling is planted in spring, it often encounters low temperature and rainy weather, which will cause bad seeds to affect the whole seedlings. The use of high quality seedlings with good germination rates, strong growth potential, preservation of seedlings, and early maturation is the key to winning high yields and stable yields. Early cultivator and early topdressing, promote flower growth, increase growth, prevent growth, soy bean production is a mid-tillage crop, seedling growth is slow and easy to produce weeds, seedling height 15 to 20 cm when the cultivator weeding soil, in order to promote Rhizobium development, earth to The cotyledon node can be prevented from lodging; in the beginning of the branching period, 5 kg of urea and 7 kg of potassium chloride are applied in combination with the second cultivator to enhance the number of effective litchi. Ingenious spray inhibitor, topping the heart to increase production in the flowering period with sodium sulfite 4 ~ 5 grams of water 50 kg, once a week, even spray 2 ~ 3 times, can enhance the photorespiration of soybean and reduce the consumption of photosynthesis products; The removal of crowns in the first 20 days can increase the seed setting rate by 7% to 8%. Prevention and control of pests and diseases, pre-increase in the protection of crops to protect the early stage of income, aphids, floor tigers, borers, mid-bean pods, eight-star ladybugs and leaf spot disease, harm the young leaves, spikes, eat pods, should choose the counterpart Pesticides prevent and cure in time.
