Soybeans grow vigorously and the leaves are dark green. They seem to be normal. However, they do not set pods or have few pods at the pod-setting stage, which seriously affects the final yield and wastes the hard work of the season. Therefore, start from planting. Good prevention and control work is very important. 1. Choose the right variety There are many varieties of soybeans on the market, and they are also regional. Therefore, when buying seeds, you must first choose the varieties that are suitable for local planting, and secondly, give priority to the varieties that have been planted in the local area and perform well. New varieties have not been tested on a large area in the local area and should be purchased with caution. At the same time, it is recommended to go to the local agricultural supply store to buy them. Do not shop online or sell Sanwu products in the countryside. 2. Reasonable dense planting Some farmers worry that the amount of planting is too small and the yield will be affected, so they will increase the amount of sowing. In this case, when the soybeans enter the flowering period, the field ventilation and light transmission are weak, which is not conducive to the normal growth of soybeans. It is prone to not forming pods. The sowing density of soybeans can be judged according to the fertility of the soil and the shape of the plant. Under normal circumstances, it is sufficient to plant 18,000 to 20,000 plants per mu in a normal plot. If the soil fertility is average and the plant shape is large, It is enough to sow 13,000 to 15,000 plants per acre. 3. Water management Soybeans are more sensitive to water requirements before and after the flowering period. Long-term drought or long-term water accumulation will affect normal flowering, resulting in no pod formation and high temperature in summer. If there is no rainfall for a long time, the field is easy to appear Drought, when the water absorption is insufficient, flowering will be affected. On the contrary, summer is also a rainy season. If there is rain in the area for a long time, there will be accumulation of water in the field, which is not conducive to flowering, and the phenomenon of no pods or too few pods will appear. Therefore, proper irrigation or drainage is also important according to local conditions. 4. Nutrient management Soybeans will produce rhizobia. Therefore, in the management of nutrients, do not use too much nitrogen to avoid flourishing growth. At the same time, the supplement of boron fertilizer is also critical. When boron is deficient, it will affect the flowering and pod formation of soybeans. Therefore, When planting soybeans, don't just pay attention to the use of nitrogen fertilizers. Phosphorus, potash, and boron fertilizers should also be supplemented in time. 5. Pest management The harm of pests and diseases to soybeans will also cause no pod formation, such as bean pod borer, leaf roller borer, downy mildew, etc., which need to be sprayed in time for prevention and control. Insecticides can be lambda-cyhalothrin, emamectin benzoate, and chlorine. For tartanide, metalaxyl, manganese, chlorothalonil, etc. can be used as fungicides.
