Pruning and shaping of young trees are carried out simultaneously. Before the new shoots germinate, methods such as removing the core, cutting short, draining and smearing buds are used to inhibit the growth of branches and promote branching. It should be light rather than heavy, mainly cutting off cross branches, over-dense branches, bent branches, weak branches and ears that don't allow them to bear fruit, so that nutrients can be effectively used and the crown can be expanded. After pruning, the wound is coated with antiseptic film to make it heal quickly.
