Kidney bean planting: when to apply boron fertilizer to kidney bean?

When is it good to apply boron fertilizer to kidney beans? Please give guidance generally in order to improve the flowering and pod setting rate of kidney beans, reduce the drop of flowers and pods, vegetable farmers often apply boron fertilizer at the flowering stage. Over time, habit becomes natural, and the application of boron fertilizer at flowering stage has become a routine technical measure for vegetable farmers to prevent kidney beans from falling flowers and pods. However, the effect of supplementary application of boron fertilizer in kidney bean flowering stage is not good, the reason is: first, the application of boron fertilizer at flowering stage can not change the problems caused by boron deficiency in the early stage, and the effect can not be achieved immediately. Second, when boron fertilizer is applied at flowering stage, the solution will wet the flower stigma and directly affect pollination. Third, the requirement of boron concentration in kidney bean florescence is unknown, so it is best to avoid this sensitive period. The basic application of boron fertilizer is the best for kidney bean, which can be applied with base fertilizer before kidney bean planting, with 2 kg borax per mu, and topdressing can spray 600 times borax or 1200-1500 times boron 7 days before flowering, and the effect is better. In addition, it should be emphasized that boron deficiency in some vegetable plots is mostly caused by soil drought, which hinders the ability of plant roots to absorb fertilizer. Therefore, in the kidney bean growing period, we should also pay attention to timely watering to prevent excessive soil drought.
