What's wrong with soybeans with horns and no firstborn?

1, poor management of water and fertilizer.

There is no continuous cropping of soybeans planted in cutting-edge ecology. This is newly reclaimed land, and soybeans were planted in the first year. The land is barren, no chemical fertilizer is needed, and some septic tank manure is used for topdressing. The water retention capacity of soil is very poor. When the weather is dry, there will be water shortage for two or three days and the soil will be dry. Because soybean lacks water and fertilizer, soybean seedlings are short and malnourished, with only long pods and no beans.

Too much water and fertilizer can also lead to the growth of soybean seedlings in vain. Especially when the nitrogen fertilizer content is too high, soybean seedlings grow vigorously, and it is difficult to carry out photosynthesis after flowering, and there will also be cases where long pods do not bear beans. Too close planting of soybeans will also affect photosynthesis.

2. The problem of climatic conditions.

If soybeans are planted in open space, they are easily affected by climatic conditions. In Jiangxi, soybeans are generally sown in March-April, harvested in June-July, sown in July-August, and harvested in June at 5438+ 10. The yield of autumn soybean is obviously lower than that of summer soybean. In the local countryside, this kind of soybean is also called "June explosion", which means it will mature in June. Avoid 7~8 portions of high temperature and high humidity weather during soybean flowering and pod setting. When the temperature is higher than 28℃, the growth of soybean will end early. If the temperature of soybean during flowering and pod setting is higher than 30℃ for a long time, it will seriously affect soybean pod setting. In our local countryside, soybeans are usually harvested at the end of June and the beginning of July, just to avoid the high temperature in July and August affecting soybean production.

Conclusion: Soybean only produces pods but not beans, which is also related to plant diseases and insect pests, and there are other reasons. In the absence of disease, the main reasons are these two.
