First, avoid high temperatures. Beans do not like the high temperature, the higher temperature often causes bean pods grow longer and fall out of flower. The temperature in the spring shed is relatively high. If we do not pay attention to strengthening the ventilation, the flowering fruit setting rate of the beans will not be very high, and even if they are seated, the flowering and falling will occur. Therefore, if you want to get a high yield of beans, it is very important to regulate the temperature of the flowering period. Under normal circumstances, the most suitable temperature for flowering beans is 20-24°C. When the temperature is higher than 24°C, the fruit setting rate will drop. If the temperature is higher than 28°C, serious flowering and falling will occur. Second, avoid watering. "Dried flowers and wet pods" are the main points of flowering bean management. Watering the flowering period will cause the falling of the beans. Therefore, the flowering period must be carefully watered. In order to prevent over-drought of the soil in the shed during flowering, it is recommended to slip small water in the planting ditch before flowering to ensure that the soil in the bean flowering period is not too dry. 1, before flowering to control the main water, if the soil moisture is not good, only about 10 days before flowering, pour 1 small water for flowering needs, and then until the fruit to sit and grow to about 4 centimeters Then water it. 2. If watering too much before flowering, soil moisture is too large to cause plants to grow and fall. 3, but not too much control of water, soil drought will also lead to poor flower bud differentiation and fall out of flower. Therefore, when the soil is too dry, the water needed for plant growth and development should be supplemented with a method of lightly pouring water to avoid falling down. If you do not master the amount of water, or to use a sprayer to irrigate as well, the irrigation amount of each plant can be about half a catty, and then when the soybean meal grows to about 4 centimeters and then add water by watering. Third, avoid boron deficiency. The lack of boron fertilizer is also one of the important causes of flowering and falling in the corner of the bean. Therefore, it is necessary to make up the boron fertilizer in the early stage of flowering. Can be sprayed with 1000 times liquid boron fertilizer, can significantly improve flowering fruit setting rate, to avoid falling flowers and falling. It needs to be emphasized that the lack of boron in some vegetable fields is mostly caused by the impossibility of obstructing the ability of the roots to absorb fertilizers due to the excessive drought in the soil. Therefore, the soil during the flowering period of beans must be kept dry and moist. Fourth, avoid using drugs. Kidney beans should be banned with chemicals containing pyrimethanil, mancozeb, anthraquinone, and anthrax. The copper preparations should also be halved. During the flowering period of cowpea, it is more sensitive to pesticides and is often susceptible to phytotoxicity, especially to pyrimethanil. Therefore, when the beans are used in medicine, they must not be selected to contain the above-mentioned ingredients. Spraying such pharmaceuticals will not only cause yellow leaves, but also cause serious fall and fall. In addition, when the drug is used, it should also be noted that the concentration of the drug solution should be scientific and reasonable, and the spraying should be stopped during the flowering period in order to avoid phytotoxicity, which will lead to the occurrence of pods.
