In the early spring, when the sprout is expanded, some quick acting nitrogen fertilizer can be applied, and the fertilizer can be applied near the root. The root can be absorbed, which can promote the new shoots to become strong, and also can improve the yield. At this time, fertilization is very important.

The main fertilizer is boron fertilizer, and some microbial sweeteners can be selected. At this time fertilization effect is more significant, can improve photosynthesis, material can also be transformed, for later flowering, insemination, fruit, etc. have a good effect.
