1. When shaping and pruning plum trees, it is necessary to leave more strong branches in the middle and lower parts of the tree crown, which is beneficial for the rejuvenation and renewal of flower shaped short fruit branches and short fruit branches.

2. When shaping, use multiple main branches in a natural and open shape, with a fixed stem height of 40cm, retaining four resident branches, and an opening angle of 60-75 degrees. Strive for even distribution and consistent height of only the three main branches; For those with four or more main branches, the main branches should be arranged in a staggered manner, and long axis fruiting branches and large bouquet shaped short fruit branches should be directly cultivated on the main branches.

3. When pruning, a combination of thinning and thinning, thinning and thinning, and controlling the upper and promoting the lower methods should be adopted, with the focus on the results.

4. When multiple strong and vigorous branches can grow at the front end of the branches, the dense branches will affect the light of the plum tree, and the light cannot enter the interior of the crown. Therefore, during pruning, it is necessary to loosen the upper and outer branches of the crown, especially those that extend the main branch. It is necessary to cut off the branches and leave one branch for light pruning and slow extension.

5. For nutrient branches with strong growth potential, those that cannot be left as fruiting branches should be promptly pruned.

6. For temporary fruiting branches that grow too densely, in order to improve lighting, a small portion can be cut off appropriately, which is beneficial for ventilation and light transmission of plum trees

7. For one or two-year-old branches that grow diagonally or horizontally, they can be lightly pruned and elongated, which is beneficial for the germination of buds at the base of the branches.

8. For flower shaped short fruit branches and short fruit branches that have been fruiting for three to five years, thinning them from the base during aging can effectively maintain strong fruiting ability.

9. For perennial fruiting branches, pruning or not pruning is possible due to decreased fruiting ability.

10. For plum varieties with strong resistance to low-temperature freezing damage and high fruit setting rate during the flowering period, it is necessary to prune short fruit branches in the form of strong or overly dense flower clusters, as well as thin or weak flower clusters.

11.For plum varieties with high fruit setting rates on annual short fruit branches and strong medium fruit branches, it is advisable to retain high-quality, internal and external medium and short fruit branches as much as possible for fruiting, which is beneficial for high yield and quality of plums.
