Analysis of Soybean Field Management Promoting High-yield Technology
Second, chemical weeding chemical weeding can increase production by 20%. Before sowing soybean seedlings, 80 ~ 100 ml of 45% bean curd lotion per acre, or 60 ~ 80 ml of 50% diammonium EC is uniformly sprayed on the surface. During the growing period of soybean, use 25% tiger water agent per acre of 70-130 ml, or 10.8% of high-efficiency herb to 25 ml of stems and leaves. 3. Drought-Resistant Soybeans are both afraid of drought and not resistant to waterlogging. They are very sensitive to water reactions during the flowering stage. This requires the soil to remain mildly moist, and long-term drought or continuous rain can cause severe death. Therefore, in drought-stricken conditions, drought should be avoided, and in case of rainy weather, attention should be paid to trenching and drainage in order to prevent waterlogging in the field and ensure rain and dry weather. Fourth, clear the yellow-leaf soybean into the mature period of grain filling, dredged the old yellow leaves in the middle and lower parts to prevent the closure of the field and avoid falling out. When 70% of the soybean meal was full, all the leaves could be removed to make the grain full and mature. Fifth, flowering, fertilization, and fertilization are the best results before or after flowering. Generally urea urea 4 ~ 5 kg, can also be used 0.2% of potassium dihydrogen phosphate and 0.05% of ammonium molybdate mixed liquid foliar spray, spray usually 1 to 2 times. Six, spraying paclobutrazol anti-growth If the plants are long, closed, in the early flowering period with paclobutrazol 150 mg / kg or full flowering period 200 mg / kg spray, can inhibit plant height, control internode elongation, reduce growth rate. VII. Spray pesticides in time During the calyx, the leaves grow green and are susceptible to various pest attacks. The Mu with 25% of insecticidal double 200 grams of water and 50 kilograms of water sprayed on the pods and leaves can effectively control the pods. Defects of cockroaches, borers, and roundworms. Mushroom extracts are mainly polysaccharides and saponins, which have immunomodulatory effects and have recovery effects on some chronic inflammation. Commonly used extracts such as mushroom polysaccharides, ganoderma polysaccharides.

First, when the seedlings picking up the heart-breaking bean seedlings grow 4 to 5 true leaves, picking up the growing points of the bean sprouts can not only effectively prevent the plants from becoming long and lodging, but also help the grain filling mature. However, when topping, it is important to note that land with a thick soil layer, good fertility, and a thin soil layer and poor fertility cannot be extracted.
