During the growth of fruit trees, some branches and buds should be combed out from the base in time, which will slow down the growth of upper branches and promote the growth of lower parts. In addition, the long branches, weak branches and over-dense branches should also be thinned to increase the light transmittance of plants and increase the photosynthetic area, which is beneficial to the arrangement and growth of fruit trees.

What is retraction? From the perspective of thinning fruit trees, it is necessary to remove some perennial branches. The drooping branches of fruit trees are weak, even if the quality is poor, they need to be recovered and updated. When two branches cross, they will affect each other and should be taken back. The saplings show a strong top advantage. Medium-long branches sprout from the top of the branches, which will keep branching and increase in turn. With the increase of branches, the length of transportation channel increases, and the number of flowers and fruits increases, which leads to the drooping of branch tops. When the top drops to a certain extent, due to the decrease of height, the growth potential gradually weakens, the dominant position gradually moves to the back, the branches at the back gradually flourish, and the branches continue to branch, blossom and bear fruit.

The branches of this fruit tree grow repeatedly and need to be pruned in time to achieve better canopy lighting and nutrient absorption of the branches. But some experts put forward the following principles on how to cut. Pruning method, as long as you remember the pruning strategies such as tree species, tree shape and tree age, let the fruit trees bear more fruits and maintain a certain tree shape. There will be more fruit.

The first principle: the tree will not die if it is visible, and it will not be chaotic if it is invisible. The so-called combination of spirit and shape means that in the process of fruit tree pruning, we should master the tree shape flexibly according to the actual situation of the tree shape, and we can't mechanically apply the pruning theory, prune the branches at will and mechanically shape them. The so-called "stealth is not chaotic" means that when the branches are handled flexibly according to the actual situation of the tree, the crown must meet the basic requirements of the tree structure of the fruit tree for pruning, and the branches and leaves cannot be chaotic.

The second principle is to trim the tree into a perfect shape with branches. The so-called "pruning by tree" refers to the comprehensive consideration of the whole fruit tree, that is, the consideration of tree species, variety characteristics, tree age, tree potential, and the balance between growth and fruit. Generally speaking, it is necessary to determine the method and degree of pruning and give full play to the role of local pruning measures. From the analysis of local parts of fruit trees, that is, according to local growth, branch number, branch type, angle, direction, number of flowers and fruits, etc. Local pruning should be judged in the case of the whole tree, and it should also be handled locally and as a whole.

The third principle: give priority to light cutting and combine light and heavy. Light cutting mainly means that the proportion of branch weight to the total weight of trees is low. The so-called "combination of light cutting and heavy cutting" means that on the basis of light cutting of the whole tree, in order to increase the total growth, it is necessary to control the heavy cutting of some parts according to the needs of plastic results to promote flowering and fruiting.

Generally speaking, in order to observe fruit trees at different growth stages, it is necessary to adjust and prune the growth of fruit trees properly so as not to affect their growth and fruiting. Trim moderately, not excessively and slightly. , combining length and length.
