Peach tree is a light-loving tree with strong branches and fast growth. If the management is not good, it is easy to grow white, which will affect the light, cause the dead branches to be empty, and the results will move out, leading to premature aging of trees and reducing the yield and quality. Therefore, it is very important to master the measures related to pruning, especially pruning in summer. The common pruning methods are: 1, fixed drying, cutting peach trees 60 ~ 70cm off the ground after planting, leaving 20 cm after cutting, and using 7 ~ 10 strong and full leaf buds as plastic belts. The so-called plastic belt is a section of trunk selected at the time of drying, which is located below the incision and above the trunk, and three main branches are cultivated in the belt. 2. Cultivate the main branches, and when the new branches grow to 50 cm a year, start to select and keep the main branches. We can cut off the central branch, make use of the annual shoots sprouting from the trunk or the secondary branches of that year, choose the one with appropriate distance and orientation as the main branch, cut off the central branch above the third main branch, and open the main branch angle by pulling branches in August-September. 3. Select and keep the side branches on the main branch. Generally, 3 ~ 4 lateral branches are selected on the main branch. The so-called lateral branches are the fixed backbone branches planted on the main branches, and the above steps can be completed by adding plastic pruning technology. 4. The reserved azimuth of the three main branches is preferably 120 degrees, which are evenly distributed, and the opening angle of each main branch is 45 degrees.
