The young age of peach trees refers to the young age of peach trees that have no fruit and few fruits 5-6 years after planting. The tree is characterized by upright branches, vigorous growth, large amount of branches, many branches, long fruit branches and secondary branches. Although the branches are easy to flower, there are few flower buds, low fruit-setting rate and high fruit-bearing parts. Therefore, the primary task of pruning is to make full use of the auxiliary branches combined with winter and summer pruning, cultivate the main branches and fruiting branches at all levels, pay attention to the angle of opening and branching, balance the tree potential, and prevent the upper branches from being strong and the lower branches from being weak. The amount of pruning should be light rather than heavy, so that the tree can be as gentle and fruitful as possible.

In order to prevent the rapid outward migration of the fruiting parts in the future, the heads of the main branches should be appropriately cut short every winter. The cutting length is generally 40 ~ 70cm. In order to maintain the affiliation, the main branches are longer and the side branches are shorter. In order to maintain the balance of branches, the weak are long and the strong are short. Strong branches should be selected in the middle and lower part of the main branches, with short sections of 30 ~ 40 cm, and become large and medium-sized branches after continuous culture. Competitive branches and straight branches should be drained or controlled in time. In the process of transforming into branches, we should pay attention to the combination of pruning in winter and summer, remove the strong and leave the weak, remove the straight and leave the flat, make the leading branches bend and extend, and maintain the subordinate relationship between branches and groups.
