1, pruning time

Pruning time of peach trees can be carried out in summer and winter, generally from May to July in summer, the first pruning in May, the second pruning in early June and the second pruning in early July. Winter usually lasts from the end of 165438+ 10 to the beginning of 65438+February.

2, young tree pruning

Pruning of small trees usually begins after transplanting. The main purpose of pruning young trees is to enlarge the crown, and the selection methods are light pruning and short pruning. We need to trim the messy branches at the lower part of the small tree, leaving only some branches and leaves.

3. Prune trees in the first fruiting period

Tree pruning at the initial fruit stage mainly refers to the pruning of peach trees at the beginning of fruiting in recent two years. At this time, the fruit of peach trees is still relatively small, so the main purpose of pruning is to reshape, facilitate the later harvest and improve the fruit setting rate of peach trees in the later period. Generally, the method of light cutting and long putting is adopted to slowly cultivate the fruiting branches.

4. Prune trees in full fruit.

Pruning of peach trees in full fruit period is also the most critical, which will affect the growth and fruit yield of peach trees. We need to extend the flowering period of peach trees on the basis of maintaining their growth, which can increase the yield of peach trees to a certain extent. This is the pruning principle of peach trees. The dead branches, old branches, diseased branches, weak branches and dense branches are gently cut off to promote the growth of new branches and maintain the illumination and breathability of peach trees.

5. Pruning at late growth stage

Pruning of peach trees in the later period is also a stage of slow senescence of peach trees. At this time, pruning is mainly to prune the old branches and re-cultivate new branches, because the previous branches are basically aging, and its fruiting ability is degraded. The fruit yield is greatly reduced, the fruit is small, and the taste is not good. It is necessary to prune all these branches. This can prolong the service life of peach trees and maintain the yield and quality of peach trees.
