The early growth of pear seedlings is different, so it can be trimmed and shaped according to the current tree shape. The commonly used tree types are layered, and trunk type, hedge type, small crown fast-growing delayed open heart type and so on can also be used. Generally, pear seedlings with small crown, fast growth and delayed heart shape have obvious apical advantages and few branches, which are not conducive to plastic surgery, so their apical advantages should be slowed down as much as possible. Kerning can slow down the top advantage of pear trees, increase the number of secondary branches and accelerate the shaping and cultivation of branches. Coring is generally cut from semi-lignified or lignified parts and carried out in June-August.

When the strength of the three main branches is the same, it is important to keep the long branches, cut off the weak branches, keep the strong main branches, and remove the dead branches, diseased branches and excessive branches, so that when the fruit trees are ventilated and light-permeable, the incision is slightly inclined, and the anti-corrosion film is coated at the pruning mouth in time, which is also very important for the branches that are pulled out in autumn. Because the length and extension of branches of young pear trees are not obvious in early spring, after a summer,

Autumn pruning refers to pruning after new branches stop growing and before harvesting. During this period, flourishing trees or pear trees with better soil management often have too many strong branches, poor indoor lighting and too many branches. At this time, mainly through pruning, a small number of new branches and long branches can be thinned and the tree potential can be improved. Generally, pear trees grow vigorously in the young stage, which is easy to form the phenomenon of strong trees and weak trees, but after a large number of fruits are hung, the tree potential will be alleviated or even weakened. When pruning, young trees are strong, mainly with light cutting and slow release, and less short cutting. The central trunk bends and bulges, and there are many branches at the base.

At all levels of the tree, the growth potential of the main branch is stronger than that of the side branches; For trees with a central trunk, the growth potential of the central trunk is slightly stronger than that of the lower trunk. Otherwise, there will be no distinction between master and slave, and there will be tree disorder. This master-slave relationship should be cultivated and adjusted from the young tree stage. All the multi-headed lateral branches will not form flower buds. By pinching, restraining and promoting germination, only short branches will be formed at the base and middle part, but no flower buds will be formed. What should we do? We can pull branches in summer and autumn, and the droop should not exceed 120 degrees.
