2. Leave as many leaves as possible and cut them lightly. Shatangju is an evergreen fruit tree with long leaves and a lot of nutrients. Leaves are organs that produce nutrients through photosynthesis, so there are many fruits in the leaves, and the branches and leaves that do not overlap and are not crowded should be kept.

3. Don't cultivate useless branches. Too long branches will increase the transport distance of nutrients and water, and make the fruiting part move up. Dead branches, bald branches and overlapping branches should be cut off, and excessively long branches should be picked up.

4. Pay attention to the subordinate relationship among main branch, main branch and side branch. Branches at all levels in the crown maintain a certain subordinate order, and nutrients and water run smoothly and evenly, thus improving the growth function of the whole tree.

5. Protect the branches below. The lower branches of young trees usually bear fruit first, and even the lower branches that can't bear fruit can support the tree.
