"four taboos" in the flowering period of kidney beans

First, avoid high temperature. Kidney beans do not like high temperature, which often causes bean branches to grow, flowers and pods to fall. The temperature in the greenhouse is higher in spring, if we do not pay attention to strengthen ventilation, the flowering and fruit setting rate of kidney beans will not be very high, even after sitting down, flowers and pods will fall. Therefore, if kidney beans want to achieve high yield, it is very important to regulate the temperature at flowering stage. In general, the most suitable temperature for flowering period is 20 ℃ and 24 ℃. The fruit setting rate decreases when it is higher than 24 ℃, and serious flower and pod drop occurs when it is higher than 28 ℃.

Second, avoid watering. Watering during flowering will lead to the drop of flowers and pods of kidney beans, so watering must be prohibited during flowering. In order to prevent the soil in the greenhouse from being too dry during the flowering period, you can slide a little water in the planting ditch before flowering to ensure that the soil is not too dry during the flowering period.

Third, avoid boron deficiency. The lack of boron fertilizer is also one of the important reasons for kidney bean falling flowers and pods, so it is necessary to supplement boron fertilizer in the early stage of kidney bean flowering. Spraying 600 times of borax or 1200 / 1500 times of Suele boron can significantly increase the rate of flowering and fruit setting and avoid falling flowers and pods. It should be emphasized that boron deficiency in some vegetable fields is mostly caused by the inhibition of plant root fertilizer absorption capacity caused by excessive drought in the soil. Therefore, attention should be paid to keeping the soil dry and wet during flowering.

Fourth, avoid using drugs indiscriminately. Kidney beans should avoid using agents containing pyrimidine, mancozeb, anthrax Fumei and ethyl aldicarb, and copper preparations should also be halved. Adzuki bean florescence is more sensitive to pesticides, often prone to drug damage, especially pyrimidine. Therefore, at ordinary times, when using kidney beans, you must not choose agents containing the above ingredients. Spraying such agents will not only cause leaves to turn yellow, but also cause flowers and pods to fall seriously. In addition, in the use of drugs, we should also pay attention to the scientific and reasonable concentration ratio of the solution, and the general flowering period should stop spraying, so as to avoid drug damage and lead to the occurrence of kidney beans falling flowers and pods.
