How to promote early maturity and high yield of soybean

First, choose the right variety

Varieties with shorter plant height and sparse planting should be selected for seed selection. These varieties have relatively less water requirements and less yield loss in dry years.

Second, strengthen field management

Weeding in time. Weeds compete with soybeans for fertilizer and water, which affects photosynthesis and is not conducive to ventilation, so weeds should be eradicated in time. Shovel at the right time. When shoveling, we should deeply shovel and cultivate more soil to enhance the permeability of the soil and the ability of water and fertilizer conservation.

Third, apply sufficient base fertilizer

On the basis of the application of farm manure, the amount of chemical fertilizer is also indispensable. Phosphate fertilizer can promote the formation of protein and improve the hydration ability. Potassium fertilizer can improve the sugar metabolism of crops, enhance the bound water content of plants, and maintain normal photosynthesis. Nitrogen deficiency is also disadvantageous to drought resistance, so it is necessary to apply nitrogen fertilizer reasonably.

Fourth, increase the application of leaf fertilizer

Spraying soybean foliar fertilizer in time can supplement soybean's need for trace elements. Boron and copper in trace elements contribute to the drought resistance of soybean, enhance the stress resistance of soybean, promote the root growth of soybean and prevent premature senescence. The amino acids in leaf fertilizer can be directly absorbed and utilized by soybean to increase the nutrient uptake of soybean.

Pay attention to disease prevention and insect prevention

The main pests of soybean are aphids, heart-eating insects and so on. The diseases of soybean include virus disease, gray leaf spot, downy mildew and so on. It is necessary to observe carefully, detect and treat the diseases and insect pests early and control the diseases and insect pests in the early onset period, so as to reduce the harm to soybean and ensure stable and high yield.
