What is the reason of soybean lodging? How to avoid soybean lodging?

There are many reasons for soybean lodging. We farmers tend to plant soybeans closely, thinking that close planting can increase production. On the contrary, soybean planting should be based on the characteristics of soybean. Close planting and sufficient rain will make soybean grow vigorously, and even a little wind and rain will lead to lodging in the later stage.

In view of the lodging situation of soybean, some can be avoided and some can't, depending on the reasons for lodging. The purchased soybean seeds are bad or fake seeds. For example, after some soybeans are sown, due to the seeds, the seedlings are weak yellow, the roots are underdeveloped, and the stems are relatively thin. In the middle and late stage, it is easy to fall down when encountering strong winds and heavy rains. One is that the early vegetative growth is too vigorous, the plants are too dense and the stems are too thin.

In the middle and late stage of soybean growth, the plants grow quite tall. If you encounter extreme weather, strong wind and heavy rain for a long time, it will easily lead to lodging and production reduction. If the planting density is high, it is easier to cause lodging. If the planting density is high, the soybean has poor air permeability, poor ventilation and weak light transmission, which will easily lead to underdeveloped roots and shallow roots. When encountering extreme weather, it is easy to cause a large area of lodging, and even lead to crop failure.

Special herbicides for soybeans are generally used for grain removal and width removal. However, some farmers are afraid of eliminating the side effects of fomesafen on soybeans and voluntarily give up the best opportunity to control soybean seedlings. Because, reasonable use in the first to third leaf stage of soybean has no effect on soybean yield. On the contrary, it temporarily inhibited the growth of soybean and promoted the root system of soybean. Indirectly increase lodging resistance.

If soybean lodging occurs, chemical control should be carried out in time. According to the growth of soybean, chemical control should be carried out in time before flowering. The initial flowering period is the key period to control the vigorous growth of soybean. If fertilization is improper or there are many rainy days during this period, soybean will grow too vigorously and easily lead to lodging.
