The pear trees in Huang Guan are vigorous, and the young trees grow vigorously, tall and straight, mostly in a head shape; High germination rate and medium branching ability-nearly 3 branches 1.5 cm or more can be produced under the general cutting mouth; If the age is early, it can bear fruit in 2 ~ 3 years under general cultivation and management conditions; Short fruit branches are mainly fruiting, and each fruit table can produce two auxiliary branches, which has strong ability of continuous fruiting, light fruit drop and high yield. There is obvious axillary flower bud fruiting phenomenon in the young tree stage. According to these characteristics, the following aspects should be paid attention to when pruning:

(1) Small tree shaping

Evacuation should be layered. Because of its upright growth, it is mostly head-shaped, so it is necessary to do a good job of pulling branches and opening angles. At the same time, in order to improve the early yield, it is advisable to adopt the technology of "keeping more branches and letting them grow longer". Except for the necessary central main branch trunk and main branch extension branches, the remaining branches should be kept as much as possible, and the flowers should be promoted.

(2) Pruning trees in full fruit period

After entering the full fruit stage, the over-dense auxiliary branches should be removed in time, and the head should be lowered to ensure the illumination in the inner room; The fruiting branches retract and rejuvenate, ensuring high and stable yield year after year. At the same time, pruning needs to be done in summer.

(3) Do a good job of thinning flowers and fruits.

Because Huang Guan pear has large fruit and high fruit setting rate, it is necessary to do a good job of thinning flowers and fruits. Single fruit is the main fruit, and the fruit distance is 20 ~ 25 cm.
