1. Erasing useless buds in early spring can reduce the consumption of nutrients, improve ventilation and light transmission conditions and improve fruit quality.

2. Pulling branches can disperse the advantages at the top of branches, enrich the buds in the middle and rear parts of treated branches, increase the number of branches, and be beneficial to crown expansion and early fruiting.

3. Thinning branches is also called thinning, that is, cutting annual branches or perennial branches from the base. It is suitable for the treatment of secondary branches or dense branches under cutting with closed crown, poor ventilation and light transmission and fierce competition. Thinning branches is beneficial to enhance the ventilation and light transmission conditions of crown, improve fruit quality and increase yield.

4. Picking the heart is to remove the growing point at the tip of the new shoot during the growing period.

(1) Picking the core at seedling stage is beneficial to the crown enlargement and thickening growth of seedlings, and improves their cold resistance and drought resistance.

(2) For strong and prosperous trees, the seed setting rate can be significantly improved by removing the core from the auxiliary shoots on the fruit surface from the full flowering stage to the physiological fruit dropping stage.

5. Circumcision is suitable for the treatment of leafy trees or trees that do not bear fruit at the right age, or auxiliary branches. Circumcision can be controlled before and after, which improves the quality of middle and rear buds of treated branches, is beneficial to flower bud differentiation, flowering and fruiting, and improves yield.

6, breaking the top means breaking the top bud, inhibiting the top and promoting germination. Taking advantage of the high germination rate of pear trees, breaking the terminal buds of annual branches before germination can promote the growth of medium and short branches, which is beneficial to the cultivation of medium and small fruiting branches and has good flowering and fruiting effects.

7. Retraction Retraction is also called shrinkage cutting, which is to cut the perennial branches short. Suitable for the treatment of perennial branches or weak branches. Retraction is beneficial to rejuvenating trees, improving the quality of flower buds, increasing the number of fruits and achieving three-dimensional results.
