First of all, you must know that fruit tree shaping and pruning is the main planting skill in its information management. That is, according to the planting purpose and the growth habits of the fruit trees and fruiting, the management technique of pruning the fruit trees into a reasonable shape and structure. The pruning and pruning of pear trees should be done in various aspects according to the growth characteristics of the pear tree and branches. The tree shape is reasonable and the tree trunk skeleton is strong; the nutrients in the tree trunk are reasonably distributed and balanced; the trunk has good ventilation and light transmittance, which improves the photosynthetic efficiency of the pear tree; thereby maintaining a medium and strong tree shape, prolonging the fruiting period and exceeding The purpose of high yield, high yield, high quality and high effect.

Characteristics of pear tree shaping

Pear trees have an advantage in growing at the top and are particularly sensitive to pruning. They tend to grow more and more as they are pruned. Therefore, during the pruning period, pear trees should be treated as lightly as possible and pruned lightly to avoid excessive pruning, which will cause the pear tree to grow taller and steeper. The pear tree has weak branching ability and few branches, but good upward branch growth ability and small viewing angle. Therefore, for pear trees before they bloom and bear fruit, it is necessary to cultivate the mother branch group as early as possible to open the branches' perspective to avoid growing too fast and producing converging trunks. We can maintain it by carving buds and pulling branches. In order to make the pear tree have multiple branches, several buds can be preserved when cutting short; that is, before the round buds, cut the area with 1-2 buds open, so that more long branches can be formed and the growth will be stronger. It is well-proportioned and the short branches produced on the back side will be stronger.

However, pear trees have weak branching ability, so the long branches that grow in the early stage should be retained and utilized as much as possible to expand the initial branch volume and strive for a high yield in the early stage. Especially for some species with few and slow branches, the branches need to be sparse. We need to change their position, position, growth, etc. through reasonable pulling, twisting and other methods to turn them into reasonable branches.

When pear trees are pruned, sparse and spread methods are generally used; short cuts and shrinkage should be used according to the situation. To increase the number of branches, carving buds should be used to maintain them. The opening angle is usually dominated by pulling branches. Our goal is to make the pear tree have as many branches as possible and form fan-shaped branch groups as early as possible; when the tree is young, it is necessary to leave more branches, shape the branches, expand the number of branches, and prune them lightly; during the fruiting period, the pear tree needs to be adjusted and balanced Relationship is the top priority, identify subordinate relationships, and prune the parent branch group appropriately.

The common tree shape of pear trees

1. One side and one heart shape. This kind of tree shape usually has a trunk height of 65 cm and a distinct central trunk. Below the central trunk are staggered layers of branches. There are 3-4 branches with a spacing of 60-65 cm. The intersection angle with the main trunk is 56-56 cm. Around 63 degrees, there are 2 branches on each branch, and the others are mostly small and medium-sized branches. Usually the tree height is 3-4 meters long, the master-slave relationship is clear, and it is suitable for pear tree species with large trunks.

2. Multiple branches in a heart-shaped shape. Usually the relative density of pear trees is common in 3X4 meter long pear orchards. The trunk is about 65 cm high, with no obvious central trunk. Each trunk is equipped with 4-5 branches. The opening angle of the branches is 60-65 degrees. There are groups of medium twigs and short fruit branches directly on the top. The tree is 3 meters tall. Pear trees with these attributes have high yields, are strong, have good permeability, and have good sunlight exposure.

3. Y font. It is usually suitable for pear orchards with relatively high density. The trunk is about 50 centimeters high. There are several large branches sliding along the rows on the main trunk, in the shape of a "Y" character, and the branch angle is 50-60 degrees. Groups of large, medium and small branches and short fruit branches sprout directly on each branch. The tree is 2-3 meters tall. This type of tree is easy to manage, forms quickly, bears fruit early, and has high fruit quality.
