Field management needs to be strengthened after grape harvest.

As the tree is weak after grape harvest, the field management should be strengthened to improve the cold resistance of the plant in winter and promote the growth of new branches in the following year. Pruning Qingyuan on the basis of summer pruning continues to do a good job of heart-picking and branching, removing tendrils and thin branches, and removing diseased leaves, so as to reduce nutrient consumption and promote full bud eyes. At the same time, remove weeds in the garden and take the diseased shoots, diseased leaves, diseased fruits, withered branches and sundries out of the garden for deep burial or burning. After the application of postharvest fertilizer, 12 kg of available nitrogen fertilizer per mu was applied to promote the recovery of tree potential. If the tree is vigorous, it should be applied less to prevent the new shoots from extending late and consuming a lot of nutrients. The grape was re-applied base fertilizer before defoliation, generally 15 kg of rotten organic fertilizer and 0.4 kg of sulfur-containing ternary compound fertilizer were applied to each plant from late September to early November, and then covered with fine soil. The soil loosening, waterlogging and drought prevention combined with fertilization is 18 cm deep around the root, and the deep turning should be carried out from September to October, when the cut-off root system can heal quickly. Rain Water clears ditches and drains in time, irrigates in case of drought, and maintains field capacity of not less than 60%. The main diseases of disease prevention and leaf protection are downy mildew, black pox, rust and so on.
