What is the reason for the latest empty pods of soybean?

Soybean is a major food crop in China, which has a large planting area. The nutritional value of soybean is very high and is welcomed by many people. However, although the planting technology of soybeans is simple, the yield is relatively high. However, in the process of planting, the phenomenon of empty pods often occurs, which seriously affects its yield. So what is the cause of empty pods in soybeans? The following editor will give you a brief introduction, let's have a look!

1. Variety reasons

When planting soybeans, the selection of varieties is very important. If the variety is not selected properly, then the phenomenon of empty pods is very easy to occur. For example, some varieties with high pod setting rate and many seeds will have a higher empty pod rate. And different varieties, the growth environment and climate requirements will be different. Therefore, if the variety does not adapt to the local environment, it is easy to produce a large number of blighted grains. Especially for some late-maturing varieties, if the temperature is lower during grain filling, it will lead to a decrease in the speed of grain filling, resulting in empty pods.

2. Climate impact

The climatic environment has a great influence on the growth of soybean. When soybean is in the growth period, if it encounters drought or waterlogging, it will increase its empty pod rate. During the flowering and pod stage of soybean, the impact of waterlogging is much greater than that of drought, which will not only cause empty pods, but also lead to lodging. In addition, when sowing, if sowing is too late because of drought, it will shorten the growth period of soybeans and cause empty pods. In the later stage of growth, if the temperature is too low, it will keep soybean filling, which will also cause empty pods. High temperature will lead to the phenomenon of flowering and unfruitful soybeans.

3. Lack of nutrition in the later stage.

After entering the flowering stage, the demand for nutrition of soybean will increase greatly. Will consume a lot of nutrition, so in the late growth of soybean, we should pay attention to do a good job of fertilization, increase the amount of fertilizer. When interplanting soybeans, if there is no base fertilizer and no topdressing, many people are very likely to be malnourished when the soybeans are in full bloom. Leaves will also be due to lack of nutrition and yellow leaves, short plants and other adverse phenomena. It leads to the appearance of weak pods in late pods or flowers in the same node, which is generally more common in varieties with poor soil fertility and large number of flowers and pods.

4. Imbalance of nutrition proportion.

Soybeans need a lot of nutrients in the growth process. Many people will ignore the supplement of some trace elements, such as boron and molybdenum, etc., the lack of these two elements is also the main reason for the empty pods of soybean. Boron and molybdenum is also an indispensable trace element in the growth of soybean, which is directly related to the podding of soybean. If there is little boron and molybdenum in the soil and topdressing is not done well, it will certainly lead to an increase in the empty pod rate of soybean. Especially in the continuous cropping plots of soybeans, the empty pod rate will be higher every year than every year.

The above is a brief introduction to what is the cause of soybean empty pods. That's all for today's introduction. This article is for reference only. I hope it can help you all.
