The latest course of winter shearing techniques for apples

In the process of apple cultivation, winter shearing is one of the important control measures. Fruit growers can not only trim the tree type, balance the tree potential, improve the permeability, but also increase the yield and quality in the coming year. So how to cut apples in winter? Let's get to know it.

1. Pruning time

The winter pruning time of apple is only before budding after defoliation, when the apple is in a period of growth stagnation, pruning has less weakening on the tree and better renewal effect, which is an important period for apple shaping. But apple pruning also varies from tree to tree. Winter pruning can be divided into three types: young trees, early fruit trees and adult trees according to their age.

2. Pruning young trees

The pruning of young trees is mainly carried out according to the principle of light weight, equal emphasis on shaping and fruit, and promoting early yield. All the main branches on the middle trunk can be trimmed from the base and re-germinated during the period, so that the branch age of the trunk is lower than that of the middle trunk and maintain the advantage of the middle trunk. In the second year, remove the main branches that are too thick at the base, and do not move the rest of the branches.

3. Pruning the first fruit trees

The young trees entered the fruiting stage after 5-8 years of planting, and the pruning of the primary fruit trees was mainly to clean up the dense branches between the layers and improve the light conditions of the plants, so that the fruiting parts slowly transited to the backbone branches. The dense area needs to be cleaned 2-3 times a year and needs to be cleaned within three years. After several years of cleaning, the small crown sparse lamellar shape retains 5 main branches and 1-2 auxiliary branches, while the free spinning shape needs to retain 10-13 main branches.

4. Adult tree pruning

The purpose of adult tree pruning is to improve light conditions, improve branch quality, and improve yield and quality, so the focus of pruning is to remove the overdense branches of more than two layers in batches, so that the big branches of more than two layers extend outward and have sufficient light. The crown is too high to make the plant grow and drop its head, making the plant less than 3.5 meters high. At the same time, we should also trim off strong branches, cross branches, whorled branches, long branches, keep branches bifurcated, branchlets bifurcated more after pruning, pay attention to apply healing agent after pruning to prevent bacteria from invading from the wound.
