After the grapes are harvested, it is necessary to preserve the leaves of the grapes and prevent them from falling off prematurely as an important management task. After the grapes are harvested, the leaves are still undergoing photosynthesis and increase nutrient accumulation. Therefore, attention should be paid to the protection of the grape leaves, except for the leaves with diseases and pests and the leaves that have already been withdrawn, except for the leaves that should be retained as long as possible. For those growing branches that are still growing, they should lightly pick their hearts and promote their ripening. In order to promote tree vigor recovery, preserve the leaves, prolong photosynthesis time, and promote the maturity of shoots, fertilizer should be applied after fruiting. Generally, 15 kg of compound fertilizer in Mushi and 0.3% solution of urea are used for extra-root dressing in 2 to 3 times. A vigorous tree garden can be used less or not, to prevent new shooters and consume nutrients.
