The winter pruning of young pear trees should be based on the principle of “light cut long and long leave more branchesâ€, mainly based on plastic surgery, which can promote the early results of pear trees. When shaping, the trimming methods of each part are as follows: The varieties with weak stems and less buds in the center can be appropriately short-cut, such as the sand pear line. For varieties with strong branching and germination, lateral branches can be used as the main head, and appropriate cuts. The original head was flattened to one side and cultured as a temporary result branch group. The main and side branches can be lightly cut and slowly released, and the lateral branches with appropriate orientation can be used to prolong the growth, short cut, adjust the angle and increase the sharpness. The original head can be replaced and the result can be flattened. Gradually remove it later. The varieties with weak branches should be properly shortened. Generally, the cuts are 30 to 50 centimeters, and the cut buds are left on the left and right sides to increase the effective amount. It should also be removed when there is a top bud nearby. The main branch that is continuously released slowly, when the side branches are weak, can be retracted at the branches, and the main side is promoted. The branch culture is divided into two methods: first, then cut, first cut, and then placed in winter. The Zhongyong branch can be slowly released and cultivate the middle and small branch groups. The strong branches are treated according to the situation, and the varieties with strong branching ability should be gently released first; the varieties with weak branches should be short-cut and then slowly released, so that the branches are close to the backbone branches. All the slow-moving branches are retracted after the result. Auxiliary branches are generally slow-released, and erect branches can be gently placed, and individual branches can be appropriately removed.
