Soybean cultivation: is there any way to increase production by growing soybeans?

Is there any way to increase production by growing soybeans? Please introduce the method of planting soybean in order to obtain high yield, you can refer to the following methods for management: 1. The growth and development of soybean is the most exuberant in the flowering and podding stage of topdressing, which is the period when soybean needs the most fertilizer in its life. The application of flower and pod fertilizer can reduce the shedding of flowers and pods, promote the fullness of grains and improve the quality. The flower and pod fertilizer should be applied at the early flowering stage, and the combination of nitrogen and phosphorus fertilizer should be applied at the early flowering stage, urea 3MUE 5kg / mu, P 7.5MUE 10kg / mu, opening holes at 5 cm on the root side of soybean, and then applying soil to cover the fertilizer. 2. Spraying foliar fertilizer except nitrogen, phosphorus and potassium, boron, zinc and molybdenum is an indispensable trace element for soybean. Therefore, spraying multi-element compound nutrient solution from flowering to grain filling stage of soybean has the effect of increasing pod and grain and increasing yield. The method is as follows: 500 grams of urea, 100 grams of potassium dihydrogen phosphate, 50 grams of zinc sulfate, 100 grams of borax (dissolved in hot water first) and 25 grams of ammonium molybdate are added to 50 kg of water. Spray evenly on the front and back sides of soybean leaves, spray 2 Mel for 3 times, and spray 75 kg fertilizer solution per mu. 3. Topping and coring at the right time can control overgrowth, protect flowers and increase pods. For soybean varieties with unlimited pod habits, reasonable removal of the top can also control the advantage of apical growth and reduce the shedding of flowers and pods. The method is from the peak flowering stage to the last stage of soybean flowering. Pick the apical growing point on a sunny day. 4. spraying paclobutrazol could control the plant height and shorten the Internode length. The yield of infinite pod type variety was higher than that of limited pod type variety. Application method: from 5 days before flowering to 7 days after flowering, 15% paclobutrazol wettable powder was sprayed evenly on the opposite side of the leaf after 75 kg dilution of water, no re-spraying and no leakage. 5. Spraying triiodobenzoic acid, which is a multi-potent plant hormone, can inhibit apical growth dominance and promote axillary bud development. The plants are dwarfed, the branches are increased, and the stems are stout, which is conducive to ventilation and light transmission and prevention of lodging. Spraying once at the early flowering stage and once at the full flowering stage could mature 7 days earlier, and the spraying concentration was 100 × 10 to the minus 6 power. Before spraying, dissolve the pure product into alcohol according to the ratio of 1RU to 100, and spray it evenly after diluting with water. 50kg per mu of spray solution, early-maturing varieties and poor-growing soybeans should not be used. 6. Spraying Daizhuangsu can make the plant short and strong, enhance the lodging resistance, reduce the shedding of flowers and pods, improve the quality, and increase the yield by 10%. The method of application: when the fourth compound leaf is grown, 0.1% of the solution is sprayed once. To the early flowering stage, 0.05% of the solution is sprayed once, and the spray should be uniform, 50 kg per mu. 7. Spraying sodium bisulfite is a respiratory inhibitor of light, which can increase the accumulation of dry matter. It was sprayed once at the initial stage and full flowering stage of soybean, diluted with 10 grams of sodium bisulfite and 75 kg of water per mu, and sprayed evenly, and it was better to spray in the afternoon. 8. Spraying photosynthetic microfertilizer at the early flowering stage and full flowering stage of soybean, 100 grams of photosynthetic micronutrient fertilizer per mu, diluted with 50 kg of water and then sprayed evenly.
