Improve ventilation and light transmission conditions to benefit the results of the coming year.
Third, timely spraying post-harvest fertilizer
After the grapes are harvested, they must be sprayed with foliar fertilizer in time to restore the tree vigor and enhance the photosynthetic capacity of the leaves. A mixture of 0.2% urea, 0.1% magnesium sulfate and 0.2% potassium dihydrogen phosphate is sprayed once every 10 days. Spraying 2 or 3 times can effectively increase the photosynthetic efficiency of leaves, restore tree vigor, and increase tree nutrients. It can also add nutrients and promote vines.

Sixth, timely soil loosening, flood control, drought prevention, picking, and soil are easy to be practicable. Immediately, one cultivator should loosen the soil and increase the permeability of the soil. Deep-cultivation and loose soil should be carried out from September to October, when the root system is cut off.
