Pruning the extension head: throw away the extension head of the tree with strong growth potential and sparse some auxiliary tips; The mean tree is shorter than the strong secondary tip; The weak tree is extended with small branches, that is, the extended head is short and the strong auxiliary tip is left.

The pruning of fruit branches is mainly based on long spreading, thinning and adduction, and basically no shortcuts are taken. Every 15 ~ 20cm > keep 1 on the main branch: the length of the bearing branch is 30 cm, and the distance between the branches on the same side is generally above 30 cm. For varieties with long fruit branches, keep 30-60 cm fruit branches and remove most of them. The number of branches per 667 m ~ 2 of 30 cm fruit branches is 4000-6000, and the total number of branches is less than 1 10,000. For medium and short fruiting varieties, leave 40 cm branches, the number of fruit branches is less than 2000 per 667m and 30 cm, and the total number of fruit branches per 667 m is less than 12000. Fruit branches are mainly inclined upward and downward, and there are a few branches on the back. Try not to leave branches on the back.

Results Branch group regeneration: regeneration was carried out at the base of the annual branch with the back branch with moderate growth potential; Retract the fruiting mother branch to the strong branch at the base or update a suitable new branch in the middle of the mother branch; Regeneration by using new branches on main branches.
