Pear tree saplings should be mastered in the winter with the principle of “light cut long and long leave more branchesâ€, mainly for shaping, which can promote the early results of pear trees. When shaping, the trimming method of each part is as follows:
1. The center is dry. Varieties with weak branching and less germination 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 interception. The original head was flattened to one side and cultured as a temporary result branch group.
2. Main and side branches. It can be lightly cut and slowed down, and the lateral branches with appropriate direction can be used to prolong the growth, make short cuts, adjust the angle and increase the sharpness of the sharpening. The original head can be replaced with a flattening, so that the result can be gradually removed later. The varieties with weak branching ability should be properly shortened, generally 30~50cm, and the cut buds should be left on the left and right sides to increase the effective amount.
3. Branch group culture. It is divided into first, then cut, first cut and then placed, and winter and summer tube. The Zhongyong branch can be slowly released, and the middle and small branch groups can be cultivated. 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.
