How to renew and rejuvenate the old orchard

Pruning the main branch and extension branch. When the main and side branch extension branches are weak, select the dorsal branch with a smaller growth angle as the main branch and the extension branch of the side branch in the 2-3 year old part of the main branch and the side branch, so that the original has been weakened. Remove the extension branches.

When the pruned part of the new backbone branches is weak, the backbone branches should be renewed and rejuvenated early, and the appropriate long branches can be selected in the canopy to accelerate the cultivation to replace the backbone branches. For the leggy branches that are used as backbone branches, cut and lengthen them in the first 1-2 years to slow down their growth. In the third and fourth years, cut the new branches appropriately to promote re-branching and control the results, which will affect the cultivation of backbone branches. If the branches are too dense or too weak, properly treated, new backbone branches can be cultivated to form a new crown in the 4th to 5th year.

The pruning of senescent trees with many flower buds should shrink weak branches, promote new branches, cut new branches at fullness, and remove excessive flower buds, and adjust the size of the trees with weak branches and many flower buds. Years" reduce the burden on the tree body and promote the good development of branches.

When pruning and pruning a complete senescence tree with a crown, the principle of renewing and fruiting is the principle of pruning and pruning the whole senescence of the crown. Re-pruning, more cutting, less sparseness, and strengthening the restoration of tree vigor are the main methods. , Stimulate multiple branches. Large branches should be thinned out and wounds less, so as not to weaken the tree's vigor and shorten the life span. When cutting the branches, retract the apex of the hanging branches appropriately, leave the buds on the back under the cut, and increase the opening angle of the branches, and leave more on the back Medium and short branches and downward full buds and strong branches.

Pruning of trees with incomplete crowns has incomplete crowns. When pruning senescent trees lacking branches, the long branches should be used to cultivate new crowns. For trees with no central stem and few upper branches, choose a long branch with an appropriate upper position and cultivate a central stem. For trees with unsound main and side branches, the long branches can be used in the lack of branches, and the continuous cutting method can be used to cultivate adult plants and side branches.

The pruning of the weak fruiting branch group should retract in time to renew and rejuvenate the weak fruiting branch group, promote the growth of the branch, and gradually form the fruiting branch group. If the inner chamber space is large and there are no fruit-bearing branches, the method of growing branches or grafting at a suitable position can be used to cultivate the inner chamber branch group to restore the tree vigor and increase the yield.
