Grape pruning can be divided into: thinning pruning, short pruning, middle pruning, long pruning, long pruning, double branch regeneration, single branch regeneration and so on. (1) sparse division; Is to thin out the weak branches and useless branches. (2) Short pruning method; That is, 2-3 buds are pruned, and stubble pruning is carried out for newly loaded young trees. (3) Moderate pruning; 3-5 Bud pruning means that for the part lacking plants, in order to fill the space, moderate pruning is adopted to increase the amount of branches and leaves.

(4) Long-tip pruning and super-long pruning of 6-12 buds are generally used to extend the main vine. For example, the main vine cultivated in a shed needs to extend into the shed. (5) Two-branch regeneration refers to pruning each branch with 1-2 buds on the basis of pruning last year. However, the regeneration of double branches needs to be carried out when the main vine has space, otherwise it will lead to the closure of the shelf surface, the increase of invalid leaves and the consumption of nutrients.

(6) Single-branch update, that is, one of the original two branches is cut off, one branch is reserved, and the reserved branch is shortened again, which is called single-branch update (7) Big update and small update. The big renewal is to cut off the old vine from the base, keep a budding branch and cultivate it into a fruitful mother vine. A small update is to replace weak branches with strong ones. Make the tree forever young and prolong the fruit-bearing life.
