1. Pear tree pruning technology is to prune pear trees scientifically, that is, "the visible will not die, the intangible will not be chaotic, pruning depends on the tree, and it will follow the shape of the tree", "overall considerations, long-term planning, balanced tree "Position, with clear subordinates", "Mainly focus on light, combine light and heavy, and control flexibly", "Suppress the strong and support the weak, promote and control correctly, use light rationally, and the branch group will be strong".

2. Pear tree pruning technology must be combined with management level. The role of plastic pruning can be well reflected in well-managed pear orchards. Different cultivation modes require different pruning methods, and the severity of pruning is also different. A densely planted garden requires a smaller crown diameter and a shorter crown, while a sparsely planted garden requires a larger crown and a larger crown diameter. In short, as long as different shaping and pruning are performed according to different conditions, better results will be achieved.

3. Pear tree pruning technology must be strong and requires central leadership. It is also necessary to equip main branches around the central leader and side branches on the main branches. The central leading trunk is stronger than the main branch, the main branch is stronger than the side branches, the side branches are stronger than the secondary side branches growing on the side branches, and the growing branches are stronger than the fruiting branches. The main branches are evenly distributed around the trunk, and the growth between the main branches should be balanced. If there are two layers of main branches, there should be a certain distance between the second layer and the first layer. The two main branches on the second layer should be arranged in a direction that does not affect the light of the first layer of main branches.

4. Pear tree pruning technology: Pear trees have weak branching power and are often prone to local emptiness. The vacant parts should be filled with measures such as pulling branches, branching side buds, and carving. For overly dense branches and leaves, the method of opening "windows" should be used to solve the problem. Pear trees have high requirements for light. In order to solve the light problem, the pear tree is required to be pruned in an evacuated and layered manner with no umbrellas at the top, no umbrellas at the top, and no empty spaces at the top and bottom.
