Pear trees are perennial deciduous fruit trees. Ordinary pruning can rationalize the tree structure and improve the yield and quality. However, you can't force pear trees to be trimmed to suit your own wishes. Instead, we need to use trees as modeling methods to achieve our own satisfaction and high-quality and high-yield results.

Usually, the pruning and shaping of pear trees are carried out through scientific experiments and the present situation of pear trees. Deciding trees in advance is beneficial to shaping and pruning in the future. In fact, we need to pay attention to several points in this process.

Pear trees have obvious central stems. Pear tree has strong polarity, small opening angle and obvious central stem. The main stem is too strong, and the main branches are strong before and weak after. Young trees should be stripped of their tops, branches and corners, and the main branches should stay at the base and bend and extend to promote the growth of the main branches.

Pear has strong germination ability and weak branching ability. Generally, except for 1 to 4 long branches from top to bottom, most other branches (except the base) germinate into middle branches and short branches. Therefore, the number of pear branches is small, and the clarity of main branches is also small.

The trunk of young trees should be shorter, and more auxiliary branches should be set aside. When the number of branches is large, light cutting and slow releasing can solve the problem of branch number, promote the thickness and length of main branches, enhance the load capacity and produce results in time.

Pear mainly produces short fruit branches and short fruit branches. Most pear varieties mainly produce short fruit branches After bearing fruit, each fruit forest produces 1? 3 auxiliary buds of fruit rack. If the nutritional conditions are good, flower buds can be formed that year. The results of the second year. Therefore, the number of branches is increasing year by year.

Some fruit stalls have long secondary buds, forming loose branches. Some varieties have short fruit seats, which will form a fruit short branch group composed of several fruit short branches. Although the short fruit branch group has good effect, long economic life and relatively stable effect, the number is limited, the regeneration ability is not as good as that of the large and medium branch group, and the inner hole is easy to be bald.

Therefore, in the process of pruning, we should not only pay attention to the cultivation and treatment of short fruit branches, but also cultivate a certain number of large and medium-sized fruit branches in a planned way.

The formation of flower buds is relatively easy. Pear trees stopped growing earlier, with vigorous branches, full buds and few secondary buds. The annual branches of most varieties release slowly, and usually form good fruiting branches in the second year. However, if we don't pay attention to the appropriate leaf-fruit ratio, the burden will be too heavy, and the fruit will easily change in size or age early every year.

In the past, the commonly used tree types in southern pear areas were mainly scattered and natural, with more main branches. At present, there are open and sparse layered, disc-shaped, spindle-shaped, folded fan-shaped, oblique herringbone, fence-shaped, etc. Shape, inverted mushroom shape, three main branches open shape, oblique shape, Japanese lattice shape.
