The height of the small canopy evacuation layer in the dwarf dense planting garden should reach 70 ~ 80 cm and the height of the trunk should reach 40 ~ 50cm；; The height of the free spindle should reach 80 ~ 90 cm, and the height of the trunk should reach 40 ~ 50 cm. In the original low-stem pear orchard, the branches that touch the ground too low should be gradually retracted, thinned or even completely pulled out.

Keep an appropriate amount of auxiliary branches in the young tree period. With the growth of the tree age, gradually remove some useless auxiliary branches or change them into fruiting branches to make the tree clear.

The main branches at the base should be cut more and thinned less, which can promote the growth of branches, increase the number of branches and properly control the fruit yield; When the angle of the main branch at the base is too large, increase the angle; Appropriately thinning some branches between layers and the upper part of the crown, lightly cutting and slowly releasing the remaining branches to promote flower buds, and gradually retracting after fruiting; By delaying pruning, the growth potential of the upper part was weakened, and the leader used the method of replacing the main spike several times to alleviate the growth potential of the upper part.
