There are many taboos in the flowering period of kidney bean and its matters needing attention

The main reason for low flowering and fruiting rate of kidney bean is improper florescence management. Therefore, remind vegetable farmers friends, must do a good job of kidney bean flowering management, to ensure high quality and high yield of kidney beans. The following points should be paid attention to in production: First, avoid high temperature. Kidney beans do not like high temperatures, higher temperatures often cause kidney beans to grow long branches, flowers and pods. In spring, the temperature in the shed is relatively high. If ventilation is not strengthened, the flowering and fruit setting rate of kidney beans will not be very high, even if flowers and pods fall after sitting. Therefore, if kidney beans want to get high yield, it is very important to regulate the temperature of flowering. Under normal circumstances, the most suitable temperature for kidney bean flowering is 20-24℃. When it is higher than 24℃, the fruit setting rate decreases, and when it is higher than 28℃, serious flower drop and pod drop will occur. Second, avoid watering. Flowering watering will cause kidney beans to drop flowers and pods, so watering must be prohibited during flowering. In order to prevent the soil in the shed from being too dry during the flowering period of kidney beans, a small amount of water can be drained in the planting ditch before flowering to ensure that the soil during the flowering period of kidney beans is not excessively dry. 3. Avoid boron deficiency. The lack of boron fertilizer is also one of the important reasons for kidney bean flower drop and pod drop. Therefore, boron fertilizer must be supplemented in the early flowering stage of kidney bean. Borax 600 times solution or speed boron 1200-1500 times solution can be sprayed, which can significantly improve the flowering and fruit setting rate and avoid dropping flowers and pods. It should be emphasized that boron deficiency in some vegetable fields is mostly caused by the ability of plant roots to absorb fertilizer due to excessive drought of soil. Therefore, attention should be paid to keeping the soil dry and wet during kidney bean flowering. IV. Avoid indiscriminate medication. Kidney beans should avoid using pesticides containing pyrimethamine, mancozeb, anthrax, thiram, copper preparations should also be used by half. Kidney bean is sensitive to pesticides at flowering stage, especially pyrimethanil. Therefore, when kidney beans are usually used, they must not choose agents containing the above ingredients. Spraying such agents will not only cause yellowing of leaves, but also cause flower drop and pod drop in serious cases. In addition, when applying drugs, attention should also be paid to the scientific and reasonable concentration ratio of the solution. In general, spraying should be stopped at flowering stage to avoid phytotoxicity, resulting in large occurrence of kidney bean flower drop.
