Tree structure. The trunk is 60 cm high, the height of the tree is 3.5 m, and the crown width is about 3 m. The main branches of 10 ~ 12 are directly planted on the central trunk, which are spirally arranged without obvious stratification. The distance between main branches is about 20 cm, and the distance between overlapping main branches is not less than 60 cm. Small and medium-sized fruit branches are planted directly on the main branches. The included angle between the main branch and the central trunk is 80 ~ 90, and the ratio of trunk thickness to main branch thickness is 1∶0.4, and the spindle-shaped crown is slender.

Plastic surgery. 80 cm in the first year. Select 3 main branches under the cutting mouth, and select 2 ~ 3 main branches every year from the second year to the fourth year. When cutting in summer, the branches should be spread at an angle of 80 ~ 90, the thinning of competing branches should be controlled, and the advantages of the central trunk should be highlighted. The thickness ratio of the trunk to the main branch should be kept at 1: 0.5, and the head should be lowered when it is 5 years old.
