The task of autumn pruning is to pick the core slightly for the second time, remove closed branches, twigs and branches with low lignification, improve lighting conditions and make the shelf surface transparent. In order to use nutrients more effectively and make the density of new shoots uniform, too many unnecessary branches and buds should be wiped off as soon as possible.
Pruning in winter, the amount of grape pruning in winter is the largest, and the most branches are removed. Winter pruning is an effective method to determine the future annual output.

Matters needing attention in vine planting
1, grapes like to bask in the sun, and they will grow better with enough light.
2, grapes like a dry environment, watering is generally not done, watering should be thoroughly poured. The growing season in spring and autumn is about once every 2-3 days, and the evaporation in summer is large, so it needs to be watered once every 1-2 days. When flowering and fruiting, water less or not, otherwise it will cause fruit drop.
3. Watering in winter can increase soil temperature and prevent freezing injury. In northern China, frozen water should be poured once 10 days before the grapes are buried in the cold-proof soil in winter, and Quefuling and Wolfensohn should be sprayed once to increase the cell concentration and enhance the frost resistance and cold-proof effect.
