Sulfur-based ternary compound fertilizer can be selected for soil application; it can also be sprayed 2-3 times by 0.5%-1% potassium dihydrogen phosphate solution through root dressing. In order to improve the storability of the grape berry, the calcium foliar fertilizer can be continuously sprayed twice in the month before harvesting, which can significantly improve the quality and storability of the grape. Strictly control irrigation during the month before harvest to prevent quality degradation.
