For pruning of the main branches and prolonged branches, when the main and lateral branches prolong the branches to be weak, the main branch and the lateral branches can be 2-3 years old. Select the back branches with smaller growth angles as the main branches and lateral branch extension branches to cultivate the original branches. Extension branches removed. When the pruning part of the new backbone branches is weakened, it should be refreshed and rejuvenated as early as possible. The appropriate leggy branches can be selected within the canopy to accelerate the cultivation and replace the backbone branches. For the long branches of the backbone shoots, they were cut in the first 1 to 2 years to make their growth moderate, and the new branches were appropriately shortened in the 3rd to 4th year to promote the rebranching, control the results, and influence the culture of the shoots. The overly dense and weak branches are properly treated. In the 4th to 5th year, new stems can be cultivated to form a new canopy. Pruning of flower buds and more senescent trees For trees with weak vigor, fewer branches, and more flower buds, shrunk and cut weak branches, promote new branches, short cuts at new branches, remove excessive flower buds, and regulate size. Years, reduce the burden on the tree, and promote good growth of branches. Canopy complete aging tree pruning Crown canopy integrity aged apple trees, in line with the principle of both to be updated, but also to the results, with heavy cutting, multiple cuts, sparse, to strengthen the restoration of tree vigor based, large branch light retraction, branchlets and more updated , stimulate multiple branches. Large branches should be sparsely removed, less wounds made, so as not to weaken the tree potential, shorten the life span, when the short branches, the appropriate withdrawal of the apex of the drooping branches, cut back should be left on the back of the bud on the back, raise the branches open angle, stay more back Medium and short branches and downward shoots. The pruning of incomplete tree canopies is not complete for tree crowns. When pruning older trees with fewer branches and branches, leggy branches are used to cultivate new canopies. For trees with no central stems and few upper branches, select the appropriate long branches at the upper position and train the center. For trees where the main and collateral branches are not perfect, leggy shoots may be used at the missing branches, and continuous cutting methods may be used to cultivate the adult plants and lateral branches. The result of debilitating results is that the pruning of the branch group results in timely retraction, rejuvenation, promotion of branching, and gradual formation of the result branch group. If there is a large internal space and there are no result branches and branches, the appropriate positions can be used for branches or grafting to cultivate the internal litchi group to restore the tree vigor and increase the yield.
