What is the reason why there are no beans in soybean pods?

Soybean is a widely planted species at present, which is widely loved by everyone because of its high yield and wide use. But when harvesting every year, many growers will encounter such a problem, that is, there are no beans in the pods, so what causes this? Let's get to know it.

1. The seed is not good

Beans with bad seeds usually have problems during storage, resulting in the inability to reproduce normally when they grow. Seeds cause pods without beans is more serious, after all, the average person planting area is not too small, this generally as long as compared with others can be judged whether it is a seed problem. If it is not good to compare with others, you can plant some other varieties in the same mu of land, and you can judge it when you compare it with the harvest, but you should prepare in advance.

2. Failure of pollen fertilization

The failure of pollen fertilization can also lead to this situation, which can happen if it is affected by external factors at this stage. Common conditions such as high temperature, torrential rain and persistent strong winds cause pods to differentiate and provide breeding sites for seeds, but fertilization fails, seeds have no roots, and finally only one pod is empty. So growers should pay more attention to the weather during pollination.

3. Lack of water

Many people will cause the whole plant to be affected because of lack of water, but this only happens when it is very dry. In the dry and hot season, the water source irrigated by growers is not enough to support the growth of the whole bean seedling, and pollen is the first to be affected. At this time, the vitality of pollen is insufficient, and the probability of successful pollination decreases. Even if pollination is successful, it will lead to the failure of seed breeding due to lack of water. In the end, there are naturally more empty beans and pods.

4. Imbalance of soil nutrients.

The growth of beans in pods requires different nutrients from pods, and some trace elements may also affect the growth of beans, while pods will grow slowly as long as the three main nutrients are sufficient. When the soil nutrients are out of balance, the pods can basically meet all the nutrients they need, but the beans may stop developing because of the lack of boron, magnesium, zinc and other trace elements, the beans can not grow, and the pods continue to grow. at this time, growers see bean seedlings flourish and a pile of empty pods are harvested.

The above situations are relatively easy to lead to pods without beans, we need to pay more attention to. Other pests will also corrode the beans, but this is more obvious. We can find treatment in time at the initial stage. If there are a lot of empty pods for no reason, then it is best to compare the above situations and see if they are caused by these reasons.
