② Plastic surgery technology. 80 cm after planting, 3 ~ 5 branches germinated in the same year, 3 branches with reasonable distribution and large angle were selected as main branches, and the rest were slowly blossomed or thinned. When pruning in the winter and spring of the following year, the extension branches of the main branch were cut short at 50 ~ 60 cm, and the central trunk was cut short at the main branch 1/3, so the first layer of the main branch 1 ~ 2 side branches were selected purposefully. In the third year, according to the distance between plants, the main branches on the first floor have short cutting space, which can be put slowly after overlapping. For the second layer, cut the main branch at the branch 1/3 to promote branching, and choose 1 ~ 2 side branches to establish a good fruiting branch system in the crown. Through the adjustment of various branches, it can be cultivated into a small crown and sparse layer after 3 ~ 4 years, and it will fall down in the fifth year.
