(1) pruning and shaping of young trees

When modeling young trees, it is advisable to use small crown sparse layer shape or spindle shape. When pruning, we should pay attention to the method of bending or curve rising, and widen the angle of the main branch to prevent the middle branch from being too strong, the upper branch from being too strong and the lower branch from being too weak. Specific pruning method: light cutting and long stay on the main branch to extend the head, and leave more branches on the main branch. For the branches on the main branch, as little as possible or not, in order to increase the growth of the main branch and control the middle stem. For a tree with a strong middle, it can be happy by losing its head and become a delayed happy shape. Medium-long fruit branches are put first and then shrunk, that is, flowers are put slowly first and then retracted for culture after bearing fruit. Strong branches, combined with pulling, bending and ring cutting, have better effect. If the branches on the back are leveled or drooped according to the situation, the leafy branches will be cut off again, and the big branches will be replaced with small branches, and the newer branches will be transformed and utilized. The secondary branches of the fruit table are mostly chopped and cultivated into fruiting branches, so that the fruiting parts are as close as possible to the main branches or big branches. Pruning in the full fruit period usually adopts the method of short cutting or retraction to remove the weak and retain the strong, and pay attention to reasonable load and suitable flowering, so that the weak branches can be renewed and rejuvenated in time.

(2) Tree pruning:

The large and small branches of crisp pear are easy to become prosperous, so that the primary and secondary branches are unclear. It is necessary to deal with them after entering the full fruit stage and the tree is relaxed. In addition, there are not many branches in the branchlet group formed by short fruit branches, so it is not appropriate to prune the branches in the branchlet group, but attention should be paid to shrinking and rejuvenating the long large and medium-sized branches. For trees that grow vigorously, the medium and long branches are often thrown away first, and then taken back after bearing fruit. For intermediate branches and longer fruiting branches, the method of first releasing and then shrinking is adopted.

2. Brief introduction of crisp pear:
