1, pruning time, pay attention to the timing when pruning peach trees, mainly in winter and summer. Winter is dormant, and good pruning can promote better germination in the coming year, and more new branches will sprout. Summer pruning is mainly carried out after fruiting. Reasonable pruning can reduce unnecessary nutrient consumption and promote peach trees to resume growth faster.

2, pruning at seedling stage, peach trees need to be pruned in time at seedling stage, mainly to control the height of peach trees and top them in time. The height of the trunk is 40-60cm, and the spacing between the upper and lower branches of the trunk is about 20 cm, ensuring that 2-3 lateral branches are cultivated on each trunk.

3. Pruning at the first fruit stage refers to pruning of peach trees in the first two years. At this time, pruning is mainly for shaping, which is convenient for fruit hanging and harvesting in the later stage. Generally, the method of light cutting and long release is adopted, and the fruiting branches are slowly cultivated.

4. Prune in full fruit. Pruning in full fruit period can prolong the flowering period of peach trees and increase the yield of peach trees on the basis of maintaining their growth. The main principle of pruning is to remove the weak and retain the strong. Cut off weak branches, old branches, diseased branches, dead branches and over-dense branches in time to promote the germination of new branches.

5. Pruning peach trees in the late growth stage is mainly to prune old branches and re-cultivate new branches in the late growth stage. The seed setting ability of old branches becomes worse, which will reduce the seed setting. Pruning all the old branches can prolong the service life of peach trees and maintain the yield.
