After long-term natural and artificial selection, soybean varieties adapted to different ecological types such as local growth period, climate characteristics, soil types and farming conditions were formed. According to the difference of sowing time and growth period, soybean can be divided into four cultivation types: spring soybean, summer soybean, autumn soybean and winter soybean.

"four taboos" for high yield of soybean
First, avoid continuous cropping, the yield will be reduced by 15% Mur20%, and the yield will be reduced by 20% Mur25%; second, the white seed field will cause diseases, insect pests and rodent pests, affecting the seedling emergence rate and yield; third, cross-regional planting should be in line with local conditions to meet the requirements of the technical indicators of accumulated temperature for varieties, otherwise, it will affect maturity and reduce yield. Four taboo root topdressing, soybean root nodule bacteria have nitrogen fixation, root topdressing nitrogen fertilizer, not only cause unnecessary waste, but also damage the fibrous root, resulting in reduced yield. Only in this way can we be sure of achieving high yield of soybeans.

Sowing technique of soybean by stages
Sowing by stages can stagger the corn harvest period of fresh soybeans, which is beneficial to prolong the supply period, expand market capacity, avoid a large number of centralized listing, resulting in excessive supply, large quantity and low price, and increase production without increasing income. and can ease the labor contradiction in the busy agricultural season to a certain extent. To do a good job of sowing by stages, the key is to achieve the following four points. 1, look at the local market situation to grow fresh soybeans and corn, high yield is not the goal, the important thing is high efficiency. & ldquo; goods are precious because they are scarce & the market price of rdquo;, is always the same as that of
