(1) Prevent the upper strength from weakening. From the young tree to the first fruit, pay attention to the cultivation of the lower main branches, and adopt the method of pruning more, thinning less and bearing less, so that the main branches grow vigorously and have more branches; At the same time, the central main branch should be thinned in the middle and the big branch in the upper part, so as to widen the angle of the upper main branch, make the central main branch bend upward, and control the pruning length of the extended branches of the backbone branch, so as to promote the growth of the lower and rear side branches and prevent the phenomenon of strong upper branches and weak lower branches.

(2) Making full use of medium-long fruit branches is beneficial to the bearing of axillary flower buds. Cutting 2-3 complete axillary flower buds from axillary flower buds can improve the fruit setting rate.

(3) Strengthen the operation of promoting flowers in summer, such as twisting new buds (strong and upright, competing branches, etc. ), removing the core and trunk, and girdling or girdling the auxiliary branches, the flower forming effect is particularly obvious.

(4) The method of "cutting first and then releasing" should be adopted as the main method for cultivating shoot groups, supplemented by the method of "releasing first and then shrinking", and as many shoot groups as possible should be cultivated. Pruning 1 ~ 2-year-old branches and perennial branches, cutting more and releasing less, is beneficial to cultivate strong branches and fruit branches. After several years of results, when the motivation is weak, we should take back the update in time; When there are a large number of flower buds in the branch group, in order to improve the fruit-setting rate and increase the number of fruit-setting, it is necessary to cut flowers and put branches.

(5) Trees in full fruit.

(1) Continue to prevent the strong from becoming stronger. Bow your head and be happy at an appropriate height, and trim the big branches of the upper main branches and the upright big branches.

(2) In order to maintain the influence of branches and the ability to bear fruit continuously, we can adopt the methods of heavy pruning with strong branches, medium pruning with annual branches and no pruning with weak branches, that is, pruning more branches, thinning fewer branches and delaying fewer branches, so as to cultivate strong fruit branches.

③ Cultivate robust branches. For the weak branch group, on the basis of reducing the number of flower buds, the methods of "removing the weak and retaining the strong, removing the oblique and retaining the straight, removing the far and retaining the near, removing the dense and retaining the sparse, removing the old and retaining the new" are gradually adopted. For the weak branch population, those who have the ability to update should take back the update in time; Those who have no ability to update can be ruled out. For small and medium-sized branches, we should pay attention to culture; Recover the drooping branches in time. After some fruit branches bear fruit, they can be retracted to the strong branches and strong buds behind them; After bearing fruit in the bore, the golden mean branch should be retracted to the good branch of the 2-year-old part in time, so that the fruit part gradually approaches the backbone branch and appears solid, robust and stable; The average number of branches per meter is about 15.

④ Strictly control the number of flower buds. The big crown tree (with sparse trunk) has 1500 ~ 2000 buds and 1000 fruits. There are no more than 65,438 buds and 300-500 fruits in the leaves of middle crown tree (small crown sparse layer, free spindle shape), but no more than 400 buds and 200 fruits in the leaves of small crown tree (slender spindle shape). The flower-leaf-bud ratio of the golden mean tree is kept at about 1∶3. Try to keep a single fruit (central fruit), the fruit is reliable, the fruit is large and the quality is high.
