Yali pear tree has strong vitality, withered, young trees are flourishing, big trees are weak, branches are sparse and open, but the main branches are pointed and the angle is relatively stable. The ability to form branches is very weak, long branches and short branches only produce 1 ~ 2 long branches, and medium and short branches are easy to form flowers. Young trees bear fruit in 3 ~ 4 years, mainly with short fruit branches. Trees are mainly short fruit branches, with a small number of medium-long fruit branches and axillary flower buds. The fruit surface can germinate more than two short secondary branches, which bloom in the same year and bear fruit continuously in the next year, with few bare fruit surfaces. The compact medium-sized branches and short fruit branches formed by this branching method have good effects, long service life and stable parts. The germination ability of latent buds is weak, and the middle and lower parts of big branches are prone to baldness.

In the aspect of plastic trimming, it can be done according to the trimming method of Pak Lei system mentioned above. Young trees should be sparse and reserved, and short cutting and carving should be combined to promote the growth of long branches. The main branches and lateral branches can be properly configured, the angle should not be too large, and the extended branches should not be too long. Old trees should pay attention to keeping flowers and fruits according to the potential, dense weak and short fruit branches should be sparse and strong to improve the quality of flowers and fruits, and they can also be retracted and updated in turn at the strong branches and strong buds. At the same time, pay attention to control beforehand, promote afterwards, and make good use of new branches that have just sprouted in various places.
