Pruning method: select and keep the main branches, fix the main branches at the height of 0.5~0.6m in the current year after planting, and keep three main branches in three directions within two years after planting, and the horizontal included angle of the three main branches is 120. Instead of cutting, pull the main branch angle gradually in different years, so that the bottom angle reaches 50 ~ 60 and the waist angle reaches 70. By pruning the main stem 0.5m away from the third main branch in winter in the third year, two auxiliary branches are cultivated, and the fourth and fifth main branches are cultivated in the fourth year. Cultivate the sixth main branch on the main branch 0.6m away from the fifth main branch, and the direction should not stay in the southeast. For varieties with poor branching ability, the main branches of young trees should be moderately shortened in previous years to increase the number of branches, expand the crown and leave as many branches as possible. By slowly releasing and pulling the upright branches and competing branches, the auxiliary branches and fruiting branches are cultivated, so that the trees are plump, bear fruit early and improve the early yield. After 4 years, the main branches and trunk are lightly cut, the upper part is thinly cut, and the lower part is moderately shortened to increase the effective amount. Results the configuration of large branches: the first layer of main branches is equipped with two large branches, the first large branch is cultivated on the anticline side 0.5 ~ 0.6 m away from the central trunk; Cultivate the second branch group at a distance of 0.5m from the first branch group, leaving 1 large branch group on the second layer; The big fruit branches are not cultivated on the central trunk, but on the middle branches.
