Pruning of peach trees in the first year is mainly based on fixed stem and main branch culture. The fixed dry height of peach trees is generally about1.2m, which can be adjusted according to the actual situation. Generally, it is open, leaving 3-5 main branches, and paying attention to cutting off the back branches to ensure the tree shape is regular and form a high-yield tree shape. Pruning peach trees: short cutting: also called short cutting, that is, cutting off a part of annual branches, cutting more is called heavy short cutting, cutting less is called light short cutting, and the middle is called medium short cutting.

The characteristic of chopping is that it greatly stimulates the buds after cutting. After short cutting, the germination ability of branches is improved, and the ability of forming branches is enhanced, and the effect of medium and short cutting is the best. Shortcuts can weaken the thickening of mother branches. Thinning: Thinning annual or perennial branches from the base. When the thinning is weak, the above effect is not obvious at the pruning position, but it still promotes the growth of the whole tree. Truncation: it is characterized by promoting the growth of branches and the germination of latent buds at the back of branches, while weakening the mother branches. Pruning is not only with scissors, but also with many pruning techniques. Growth: 1 year-old branches are not pruned, and some branches are selectively grown when pruning, which can promote more fruiting branches or fruiting parts. For young trees, more branches should be used, and the branches with better growth should be used as auxiliary branches.

Pull the branch: widen one corner of the branch with a rope, and fix one end of the rope on the ground or tree, or support one corner of the branch with a wooden stick, or drop the branch with a heavy object. Taking branches: bend the annual branches gradually from the base by hand, try not to break the xylem, and make the branches naturally horizontal or slightly downward at the top. The best time to pick branches is the turn of spring and summer. At this time, the branches are semi-lignified, the operation is simple, and the growth effect of the branches with strong opening angle weakening is the best, which is also conducive to the differentiation of flower buds and the rapid formation of fruiting branches. The newly planted peach trees began to enter the fast-growing period in the first half of June. The first summer pruning can be carried out when the new buds germinate more than 60 cm, and the second and second summer pruning can be carried out in mid-July and mid-August.

Pruning method: peach trees have strong demand for light, strong top advantage and short life of latent buds. If the main branch is too straight, it will cause the front branches to flourish and then wither, which is not conducive to the three-dimensional effect. If the vigorous branches on the skeleton are not controlled, it will not only affect the light and disturb the tree shape, but also cause the confusion of primary and secondary branches, which is not conducive to flowering and rapid expansion of the crown. If the pruning is too heavy, there will be too few branches left, especially if it is too late in summer. If some overgrown competitive branches grow to the extent of "trees on trees", they must be treated once, causing serious tree weakness and gummosis. Therefore, shearing wool in summer must be reasonable.
