Many taboos during the flowering period of kidney beans, keep these precautions in mind
The main cause of low flowering and pod-setting rates in kidney beans is improper management during the flowering period. Therefore, vegetable growers are reminded that they must manage the flowering period of kidney beans well to ensure high quality and high yield.

The main cause of low flowering and pod-setting rates in kidney beans is improper management during the flowering period. Therefore, vegetable growers are reminded that they must manage the flowering period of kidney beans well to ensure high quality and high yield. In production, the following points should be noted:
1. Avoid high temperatures. Kidney beans do not like high temperatures, and higher temperatures often cause excessive vine growth and flower and pod drop. In spring, the temperature inside the greenhouse is relatively high, and if ventilation is not strengthened, the flowering and pod-setting rate of kidney beans will certainly not be very high, and even after pods set, flower and pod drop will still occur. Therefore, if you want to achieve high yield in kidney beans, regulating the temperature during the flowering period is very critical. Generally, the most suitable temperature for kidney beans during the flowering period is 20-24°C. When it is higher than 24°C, the pod-setting rate decreases, and when it is higher than 28°C, serious flower and pod drop will occur.
2. Avoid watering. Watering during the flowering period will cause flower and pod drop in kidney beans, so watering must be prohibited during the flowering period. To prevent the soil in the greenhouse from being too dry during the flowering period of kidney beans, a small amount of water can be run through the planting furrow before flowering to ensure that the soil is not too dry during the flowering period.
3. Avoid boron deficiency. Boron deficiency is also one of the important causes of flower and pod drop in kidney beans, so boron fertilizer must be supplemented sufficiently before kidney beans flower. Spraying 600-fold borax solution or 1200-1500-fold Sulebor solution can significantly increase the flowering and pod-setting rate and avoid flower and pod drop. It should be emphasized that boron deficiency in some vegetable plots is mostly caused by soil that is too dry, which hinders the root system's ability to absorb fertilizer. Therefore, during the flowering period of kidney beans, attention should also be paid to keeping the soil from being too dry or too wet.
4. Avoid indiscriminate use of pesticides. Kidney beans should avoid pesticides containing pyrimethanil, mancozeb, anthracnose fumei, and diethofencarb, and copper-based preparations should also be used at half dose. Kidney beans are relatively sensitive to pesticides during the flowering period and are often prone to pesticide damage, especially from pyrimethanil. Therefore, when using pesticides on kidney beans normally, pesticides containing the above ingredients must not be selected. Spraying such pesticides will not only cause leaves to turn yellow, but in severe cases will also cause flower and pod drop. In addition, when using pesticides, attention should also be paid to making the concentration ratio of the pesticide solution scientific and reasonable. Generally, spraying should be stopped during the flowering period to avoid pesticide damage, which can lead to widespread flower and pod drop in kidney beans.
