How to promote early maturity and high yield of soybean
1. When selecting suitable varieties, the varieties with shorter plant height and sparse planting should be selected. These varieties have relatively less water requirements and less yield loss in dry years. Second, strengthen field management and 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. 3. on the basis of the application of farm manure, the amount of chemical fertilizer should not be applied.
