In the third and fourth years, the trunk shape of peach trees was basically formed. There are 5-7 medium-sized fruiting branches (also called small main branches) in the middle and lower part of the trunk, and 4-5 small fruiting branches in the upper part of the trunk. The crown looks like a spindle. Under the condition of close planting, the crown is cylindrical. Medium branches are composed of 5-8 branchlets, and the focus of pruning in the future is the uniform distribution of new branches and fruits and the regeneration of branches (Figure

The cutting method in winter and summer is similar to that in the second year. Mainly to maintain the growth of tree potential and the balance between growth and fruit; Retract and update the fruiting branch group properly, select and keep good and robust backup branches, control the fruit setting amount according to the trunk diameter, prevent the baldness in the crown and the fruiting part from migrating outward, and ensure high and stable yield.
