Peach trees have strong sprouting power and branches. Cutting young flourishing trees and branches in summer can not only accelerate the forming speed, but also significantly control the flourishing length, and promote the accumulation of nutrients and the formation of flower buds. The flower bud differentiation of peach trees is mainly completed in July and August in summer. During this period, a large number of overgrown new shoots will be pulled out. If they are not pruned in time, the flower bud differentiation will be affected, resulting in only long branches and leaves and no fruit in the coming year.

first, coring can control the upward movement of the result part and improve the plumpness of the flower bud, and the young trees can be formed early by coring. Generally, it is carried out for three times, that is, from mid-May to early June, from late June to early July, the top tips of the main and auxiliary shoots are cut off, so as to enrich the development of branches and improve their maturity.

2. Twisted-tip peach trees are mostly used to transform long branches into fruiting branches, and at the same time, they can improve the lighting conditions of the trees. It is suitable for the period when the new shoots are about 3 cm long and have not been lignified, and it is suitable for the twisted shoots to be 5-1 cm away from the base of the branches. Twisting should be carried out on all the excessive new shoots on the extension branches of the main branches, the vigorous shoots extracted from the upper part of the crown, and the strong shoots extracted from the cut after short cutting in winter; Twisting the tip is to twist the upright branches by 18 degrees, so that the upward growth is twisted downward.

three thinning

1. thinning green branches can improve the light conditions in the crown. peach trees are light-loving crops, especially in the flower bud differentiation period. Green branches include new shoots and multiple secondary shoots, and the objects to be thinned are: competitive branches, weak branches, drooping branches, overgrown branches and dense branches.

2. Short-cut new shoots are generally short-cut from late May to early June, and two fruiting branches can be produced. The flower buds formed by the secondary tips that are cut short and extracted too late are not full. It is better to leave 3-5 buds at the base for cutting new shoots. After August, leave 1-2 of the terminal cluster-like auxiliary tips formed after coring, and cut off the upper auxiliary tips by "coring".

fourth, pulling branches is the key measure to ease the tree vigor, bear fruit early and prevent baldness at the lower part of branches.

1. The branch pulling time is usually in May-June, when the branches are soft and easy to open and set.

2. Branching methods can be adapted to local conditions, and methods such as supporting, pulling, hanging and parting can be adopted. The angle of branch pulling is generally about 8 degrees. Generally, from May to June, the main lateral branches are pulled apart according to the requirements of tree shape, and the branch group is pulled to about 8 degrees, but it is not suitable to be pulled horizontally or droop.
