Winter pruning generally lasts from 65438+February to February of the following year. The purpose of pruning at this stage is to shape. Through shaping and pruning, we can create good ventilation and light transmission conditions for trees and adjust the relationship between aging and rejuvenation. The formula for pruning peach trees in winter is "three cuts and seven points, more work and less gain." Keep the word "light" in mind, and stick to the doctrine of the mean. Stay under the main pole and you won't grow crazy. Don't be afraid. "If you change a few poles for an old tree, you will be one meter short of planting a tree."

Pruning in growing season, also called summer pruning, refers to sprouting in spring and defoliation in winter. Pruning during growth period can relieve tree vigor, improve lighting conditions and promote flowering and fruiting. In the flowering and fruiting period, the dense branches are loosened, and the new shoots of Wang Chang are taken to remove the core, and the vertically growing branches on the peach trees are cut off, leaving the branches with strong growth in the middle for cultivating the main branches of the secondary peach trees; Pruning: It is to cut off the branches that are too thick on the peach tree and evacuate the vertical bars.

Modify the tree shape, the position and direction of the lateral branches of the trunk, and the primary and secondary branches of the trunk to facilitate ventilation, light transmission and more fruits. Pruning, as the name implies, according to the goal of pruning, cuts off redundant branches and shortens excessively long branches. The winter leisure period is after falling leaves in autumn and before germination in spring. It is best to prune in late autumn now. If you have time to relax, you can relax early. The wound is easier to heal, and then the mouth is cut open and the bud grows better.

To prune the fruiting peach trees properly, we should first delete the branches that are too dense and flourishing, and give priority to the short cutting of the tree age, so as to improve the quality of the peach trees, and at the same time appropriately increase the yield of fruit branches, which can effectively promote the growth and increase the yield of the peach trees. After the four-year-old trees are cut down in winter, the four-year-old trees are basically formed, and the main branches remain 3-3.5m, and they no longer extend outward. The extension head of the main branch shrinks once every two years, and then it is placed in a biennial place. The fruiting branches on each lateral branch are renewed and rejuvenated by means of medium weight and short cutting.
