There are many reasons why the size of the grape fruit is different in production. The main reason is that the tree vigor is weak. In the fruit formation period, the nutrients cannot satisfy the requirement of fruit enlargement. To prevent the occurrence of grape size, the first is to strengthen the management of fertilizer and water, and increase the amount of fertilizer and water supply in the grape season. Usually, a flower fertilizer is applied before flowering, and fertilizer is applied once after harvesting. Drainage ensures that the tree grows robustly. The second is to be reasonable pruning, too much flower should be carried out when the summer cut, sparsely dense branches, weak branches; the results of fewer branches, strong nutrient growth, winter shear should be properly aggravated, sparse shrinkage, control of flowering, balance tree Potential. The third is to thin the fruit, the grapes set too much, the tree nutrient consumption, more fruit drop, thinning the fruit tree load can be appropriate, maintain tree vigor, enhance the results of stamina, overcome the phenomenon of size and fruit. In addition, appropriate pollination, pest control, planting high-quality varieties and applying plant growth hormone and trace elements, etc., can improve the fruit setting rate, reduce physiological fruit drop, and overcome the phenomenon of grape size.
