There is no trunk and central trunk, and 4 ~ 5 main branches grow evenly from the ground, with fruiting branches on them and no big side branches. This kind of tree is characterized by fast forming, few backbone branches, short tree body, early fruiting, strong wind resistance, difficult lodging and convenient management, but its service life is short, and it is suitable for plastic surgery in mountainous areas, hilly areas or greenhouses.

After planting, leave 20 cm to dry, which can be divided into 1 ~ 5 first-class branches in that year; In the growing season, the first branch and its extension head are cored every 40 ~ 50 cm, and the remaining branches are 30 ~ 40 cm long to promote the growth of the second branch; The secondary branches were cored every 30 ~ 40 cm, and the remaining branch length was 10 ~ 20 cm, and the obtained branches were cultured. In the first year of cutting in winter, the first-grade branches are cut short according to the growth potential, and the branches with the length less than 70 cm are not cut, and are slowly released and allowed to grow. Branches over 70 cm should be shortened by 20 ~ 30 cm. If the number of branches is insufficient, leave 20 ~ 30 cm as strong branches, and leave all the cut buds outside. In the spring of the following year, only a few flourishing branches were adjusted. In the growing season, we should continue to pick cores, increase the number of branches and slow down the rest. The next winter basically took shape.

In the process of pruning management after molding, we should always pay attention to the timely control of the upright branches on the back, and retract the rejuvenated main branches in time after full fruit. Overdense and over-squeezed branches can remove 1 branch, which is beneficial to ventilation and light transmission in the middle and lower parts of the crown.

When pruning the edge of greenhouse with cluster branches, chemical control technology should be applied in the spring of the following year to control the tree potential and promote early fruiting, and at the same time, the angle of main branches should be adjusted appropriately to reduce the height of trees.
