Boron is an important trace element essential for crop growth and development. It has an irreplaceable effect on flowering and crusting, fertilization and fertilization. Rational application of boron fertilizer is very effective in increasing crop yield and improving quality. Boron fertilizer can increase the pod length, seed amount, 1000-grain weight and single pod weight of the beans, and finally promote the increase of yield. The increase of seed volume is 3.5%~9.5%, the increase of 1000-grain weight is 2.2%~12.3%, and the yield of fresh pods is increased. It is 9.9%~16.5%, and the total output can increase by 9.3%~15.9%.
The cultivation and cultivation network recommended that netizens use a 0.15% concentration of boron fertilizer, which is sprayed once every 7 to 12 days in the early flowering stage and the pod-forming stage. The type of boron fertilizer can be borax or boric acid. It is sprayed on the front and back of the leaf surface of the bean plant on a sunny morning or afternoon. However, because the pore is on the opposite side of the leaf surface, the reverse surface spray effect is better.
Borax is a poorly soluble chemical that must be slowly dissolved in warm water at 40 ° C. It is difficult to be absorbed by crops.
