Correct Application of Boron Nutrition in rapeseed

Some experiments showed that the yield of 0.2% borax solution sprayed once at seedling stage and bolting stage was better than that of seed soaking alone or as base fertilizer, and 11.4% higher than that without boron application. The effect of spraying at seedling stage + bolting stage + early flowering stage was better than that at seedling stage, bolting stage and early flowering stage, and 16.2% higher than that of the control.
