When is the best time to cut peach trees in winter?

In fact, we fruit farmers prune peach trees for four purposes: first, to prevent the consumption of nutrients, so that nutrients can be supplied to the new shoots, nutrient transport branches and fruiting mother branches of peach trees, thus promoting the expansion of peaches, preventing the phenomenon of falling flowers and fruits, and laying the foundation for high yield in the coming year; The winter pruning time of peach trees is in the author's local area, and it can start from June 5438 to early February every year. Premature pruning will reduce the loss of nutrients in peach trees, which is not conducive to the growth of peach trees.

In the first frost, the survival rate of seedlings planted in autumn, winter and spring is poor, even if some of them survive, they are not prosperous in the early stage. The reason is that although the temperature is low, the leaves of peach seedlings are very green, with photosynthesis and little nutrition in the roots. Short cutting is to cut off part of annual branches, reduce the position of hair branches and enhance the growth potential of new shoots. General incision requires a distance of 0.5- 1.0 cm above the bud. Short cutting can effectively weaken the whole tree, but it can promote the germination of branches below the incision.

Pruning will weaken the growth of trees now, and the growth of trees may be weakened next year, which is prone to a series of problems such as yellowing of leaves, gluing and low fruit setting rate. It is suggested to do it at 15 after the leaves are completely fallen, and then cut it after the trees are basically dormant. Thinning and pruning: it is a pruning method to cut off branches from the base and keep long fruit branches through thinning to promote the emergence of short and medium fruit branches. This method is suitable for varieties with short branches and is widely used in young trees, which can obviously slow down the tree vigor.

Pruning time of peach trees mainly includes winter pruning and summer pruning. Winter pruning refers to the pruning of peach trees from defoliation to spring germination. The main measures taken in winter pruning are short cutting, thinning, long release and internal shrinkage. From late May to early June, 6-8 buds can be left for coring, and after branching, the strong branches can be removed and the middle branches can be retained, and then a branching group can be cultivated. Generally, early enucleation can promote growth; Picking the heart in the later stage can promote development.
