Kidney bean planting: what should kidney bean flowering pay attention to?

What should kidney bean florescence pay attention to? Please introduce the flowering period of kidney beans need to pay attention to the following points: first, high temperature. Kidney beans do not like high temperature, which often causes kidney 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 also fall. Therefore, if kidney bean is to get high yield, it is very important to regulate the temperature of flowering stage. In general, the most suitable temperature for the flowering period of Yun Dou 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, watering. Watering during flowering will cause kidney beans to drop flowers and pods, 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, 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, indiscriminate use of drugs. Kidney beans should avoid drugs containing pyrimidine, mancozeb, anthrax Fumei and ethyl carbaryl, and copper preparations should also be halved. Kidney bean florescence is more sensitive to pesticides, often prone to drug damage, especially pyrimidine. Therefore, kidney beans in the usual use of medicine, must not choose agents containing the above ingredients, spraying such agents will not only cause leaves yellowing, serious will also cause falling flowers and pods. 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.
