When pruning peach trees, note the following key points:
1. The general shaping principle is "shaped but not rigid, unshaped but not chaotic," "large branches bright and open, small branches bustling." Fewer large branches allow more small branches. The general pruning principle is "prefer light over heavy," combining heavy and light. "Small branches bustling" does not mean the more branches the better; generally after pruning, the branch spacing is 10-15 cm, and branch quantity for pollen-free varieties should be 50-100% more than for varieties with pollen. Through pruning, keep the tree vigor moderate, neither overly vigorous nor overly weak.
2. Management of different varieties. The shaping techniques for different varieties are basically the same, but the pruning techniques for fruiting branches differ among varieties.
3. Pay attention to opening the light path and emphasize the role of light in improving peach yield and quality, so that all branches, leaves and fruits receive light evenly.
4. Strengthen summer pruning, play down winter pruning. Peach trees can be pruned only in summer without winter pruning, but not the reverse. Winter pruning is not omnipotent; it must be combined with other technical measures to be effective, such as summer pruning, flower and fruit thinning, etc.
5. Avoid "flat-top style" pruning. After pruning, on the same tree there should be long, medium and short fruiting branches, so as to achieve the goal of branches of uneven length, positions of uneven height, and three-dimensional fruiting.
6. Main branches should extend with a curve, large fruiting branch groups or side branches should grow obliquely, and small and medium branch groups should fill the gaps. On the main branch (side branch), the distribution of fruiting branch groups should be "jujube-pit shaped," that is, "small at both ends, large in the middle." Fruiting branches are best oblique or horizontal; on young trees, branches on the underside can be kept, but thick vigorous branches on the upper side must be removed.
