1. Cut-out buds should be cut at 3 to 4 cm on the cut-off buds. If the internodes are short, they can be cut in the previous section of the cut-off buds. Clipping should be smooth to prevent breakage, so as not to affect sprouting.
2. Branching sprigs can be removed from the base when they are sparsely branching, short piles should be left for the sparse branches, and short piles should be cut in the second year. At the same time, avoid contiguous wounds, so as not to affect the smooth flow of tissue.
3, to avoid the mouth injury on the main vine when the sparse, should try to avoid causing oral injury.
4, a reasonable determination of the length of the cut-off length of the cut must be fully mature, there is space for the site, the vines should be appropriate to stay long to complete the plane as soon as possible. The varieties with high growth rate and low basal shoot bud rate should be pruned with medium-length shoots, moderate growth or weak growth, and varieties with high seed setting rate at the base should adopt medium and short shoots for pruning.
5. If single branch updating is adopted for branch regeneration, winter shearing is the short shoot trimming of the resulting parent branch without leaving a preliminary branch, and the second year results in a new branch resulting from the parent branch, the upper result, and the lower one. The inflorescences are made into branches and the resulting branches are removed during the winter shears, and the short shoots of the ready branches are trimmed. If branch updating is used, one result is left for each result site and one for the upper part is still pruned by the middle and long tips, and the lower branch is left for 2 to 3 buds.
6. Note that the perennial dendrite renewal has perennial vines that have a weaker apex and still have a better result area at the rear end, and it retracts to grow on strong dendrite; for the perennial branches that have good branches at the front and bare behind, the vines are updated and cultivated. New plant results; perennial vines that are weakly growing. If there is the ability to produce results, when the base is not replaced by sprouts, it can be used in combination with the method of shortening and erecting the vines on the old vines to help the weak vines turn stronger and balance the tree vigor; if there are no results for the perennial old vines, Ability should be completely removed.
