"Special" tree-shaped apple trees are caused by improper pruning, poor cultivation and management, and other undesirable external factors. To grow special tree-shaped apple trees into suitable trees, they must be properly pruned and transformed.
1. Informed trees caused by indifference to growth caused the overcrowding of the crowns of such trees, regardless of primary and secondary conditions, poor illumination of the canopy, and low yields. Pruning this type of fruit tree does not require a tree. It can only be trimmed according to the specific conditions of the tree. First of all, we must open the branch angles, select some branches with promising cultivation as the main branches and side branches, and retract or appropriately remove other perennial branches each year and adjust the relationship between the branches and the branches. In some trees, there are too many main branches and the lateral branches are far from the main trunk, which needs to be properly adjusted. The main side of the tree can be used to occupy the space where the side branches of the main branch can be configured. The perennial non-backbone branches are retracted year by year to promote the rear branches to form multi-axis branches. In order not to severely reduce the production of trees, appropriate uniaxial results should be maintained. After a large number of results from the multi-axis results, the slender uniaxial results were removed.
2. Deviating canopy trees do not attach importance to the growth potential of balance trees during the pruning process for many years, or cause mechanical damage to the trees, and influences of other obstacles, etc., so that the length of the tree crown tends to one side, the tree body is too small, and the tree grows. Unbalanced, resulting in reduced ability. The method for pruning such trees is to insult them on the side lacking the main branch and adopt methods such as re-toughing of vegetative branches, support, and pulling, and try to cultivate main branches and fill vacancies. On one side of the branches of trees, remove the dense branches. When sparse branches are removed, the branches are sparse, the branches are sparse, the dense branches are reduced, and the branches where the branches are sparse are cultivated. In this way, the growth potential of all parts of the tree can be balanced in a short period of time, and the crown can be completed.
3. Small old trees that are not very old and growing are weak. Such tree pruning should not only strengthen soil management, but also increase fertilization and water supply, and must eliminate excessive flower buds. Do not leave flower buds on the extension branch of dried stems for three years. Do not extend the result on the branch. In addition to sparsely cutting flower buds, short-fruit branch groups must be appropriately retracted so that short fruit branch groups can be renewed. In addition, wounds should be avoided on the backbone sticks as much as possible, especially large wounds should be avoided so as not to weaken the growth potential of the trees and to facilitate the healthy growth of the trees.
