Kidney bean flowering management taboo

One avoids high temperatures. Kidney beans do not like high temperatures, and higher temperatures often make legumes of legumes grow longer and fall out of flower. Even after sitting and staying, fruit will fall and fall. Therefore, if you want to get high yields of cowpea, it is very important to regulate the temperature of the flowering period. Under normal circumstances, the most suitable temperature for cowpea flowering is 20°C-24°C. When the temperature is higher than 24°C, the fruit setting rate will fall. If the temperature is higher than 28°C, serious flowering and falling will occur.

Second bogey water. Watering the flowers will cause the beans to fall and fall. Therefore, the flowering period is generally not suitable for watering. In order to prevent the cowpea flowering soil from being too dry, you can slip the small water in the planting ditch before flowering to ensure that the soil in the cowpea flowering period does not overwhelm the drought.

Three avoid boron deficiency. The lack of boron fertilizer is also one of the important reasons causing the falling of the beans. Therefore, the boiled bean must be supplemented with boron fertilizer before flowering. Can be sprayed with 600 times borax or 1200-1500 times the speed of boron, can significantly improve the flowering fruit setting rate and reduce the falling flowers. It needs to be emphasized that the deficiency of boron in some vegetable fields is mostly caused by the impossibility of obstructing the ability of the roots to absorb the fertilizer due to the excessive drought in the soil. Therefore, the cowpea must pay attention to keeping the soil dry and wet.

Four taboo medications. Cowpea flowering period is more sensitive to pesticides and prone to phytotoxicity, especially to pyrimethanil. Therefore, during the flowering phase of cowpea, it must be impossible to choose pharmaceuticals containing pyrimethanil, mancozeb, anthrax, and acetylchomycin. The copper preparation should also be used in half. Spraying these agents will not only cause yellowing of the leaves, but will also cause flowers to fall out of shape when severe. In addition, in the use of drugs, it should also pay attention to the chemical concentration of the liquid to be scientific and reasonable, the general flowering should stop spraying, so as to avoid the occurrence of phytotoxicity, resulting in the occurrence of cowpea flower falling down.
