Kidney bean flowering management points

1, bogey heat cowpea do not like the high temperature, high temperature often cause bean pods grow, fall out of love. The temperature in the spring shed is relatively high. If we do not pay attention to strengthening the ventilation, the flowering fruit set rate of cowpea will not be very high. Even if we sit down, it will fall out of flower and fall down. Therefore, if you want to get high yields of cowpea, it is very important to regulate the temperature of the flowering period. Under normal circumstances, the most suitable temperature during the flowering period of cowpea 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. 2, avoid watering flowering watering will cause the beans to fall and fall, so the flowering must be prohibited watering. In order to prevent the soil of the shed during the flowering period of the cowpea from being too dry, the small water can be slipped in the planting ditch before flowering to ensure that the soil in the cowpea flowering period is not too dry. 3, avoiding the lack of boron and boron deficiency is also one of the important reasons that cause the falling of beans. Therefore, the kidney bean must be supplemented with boron fertilizer before flowering. It can spray 1200-1500 times calcium alkoxide and boron fertilizer, which can significantly improve flowering fruit setting rate and avoid falling flowers. It needs to be emphasized that the deficiency of boron in some vegetable fields is mostly caused by the impossibility of obstructing the ability of the roots to absorb the fertilizer due to the excessive drought in the soil. Therefore, the cowpea must pay attention to keeping the soil dry and wet. 4, bogey indifference drugs cowpea should avoid using pyrimethanil, mancozegan zinc, anthraquinone Fumei, etchant Weiwei pharmaceutical ingredients, copper preparations should also be used in half. During the flowering period of cowpea, it is more sensitive to pesticides and is often susceptible to phytotoxicity, especially to pyrimethanil. Therefore, when cowpeas are used in medicine, they must not choose medicaments containing the above-mentioned ingredients. Spraying such medicaments will not only cause yellow leaves, but also cause serious fall and fall. In addition, in the use of drugs, it should also pay attention to the chemical concentration of the liquid to be scientific and reasonable, the general flowering should stop spraying, so as to avoid the occurrence of phytotoxicity, resulting in the occurrence of cowpea flower falling down.
