There are four tricks to pruning grow trees
The grown-up hawthorn trees that are left to grow are generally characterized by multiple branches, whorls or overlapping each other, weak branches, declining tree vigor, bald outer densities on the crown, easy to shoot at the top, maladjustment of growth and results, and blooming of flowers. The fruit is not much fruit. For this type of tree, transformation must be carried out so that large branches and thin leaves remain, and branchlets remain. The branches on the backbone branch should be arranged on both sides. The branches do not press the branches, the leaves do not press the leaves, and the light is introduced into the earthworm to make it three-dimensional. . For specific pruning measures, methods such as sparse, retractive, short cut, and culture should be used. However, although the low-yield hawthorn gardens and the trees that have been left uncultivated and long-pruned have been trimmed, the effect of pruning is very obvious. However, pruning can only play a regulatory role. After recovering the results for 2 to 3 years, if the management of soil and fertilizer water cannot keep up, the effect of pruning will be significantly reduced. Therefore, we must look at the role of pruning in a scientific manner. We must not regard pruning as a panacea for "a pair of scissors will set the stage for heaven and earth." Only by closely combining pruning and comprehensive management based on soil, fertilizer, and water can we maintain its high yield and stable production.
First, sparse. Sparseness is the removal or retraction of dense branches. The purpose is to save tree nutrients, increase branch and shoot plumpness, and improve air and light conditions of the tree to increase light energy utilization.
When sparsely rooted stems are sparse and one tree has more than ten dense bones and stems, two or three of them should be removed from their positions due to improper position, lack of development prospects, and weakness in drawing. Branches and branches should be sparse, and branches with poor growth should be removed. If two branches cross each other, they can be lifted and pressed to make room. For three strands of fork, every three to the middle or sparse position of lateral branches. For extension branches on branches, if the two branching angles are small and the growth potential is strong, when competition occurs, the improperly positioned branches should be cut off. In combination with pruning, the pest branch and dry branches should be removed. When thinning, Zhuang trees often go upright and leave the weeping sticks; weak trees go to weak branches and stay strong branches. The outer branches of the canopy are densely crowded and the empty ones are empty. The dense places are left less and the thin places are more.
Second, retraction. The purpose of the retraction is to update the rejuvenation and cultivation of the branch, stabilizing the resulting site. For the emergence of Jiaozuo, weak or tip drooping of the backbone of branches, in a good branch of shrinking, gradually cultivated into the result Zhizu. To extend the resulting branches per year within the canopy, they should be promptly retracted to the strong branches, and the old trees must be retracted to a greater degree. The perennial branches and endophytic branches on the backbone can be retracted to the branches and transformed into the result branches. Branches that are prone to sagging, weakness, and poor results should be shrunk and cut at higher branches, raising the angle, and increasing growth. For the long-established perennial leg of the development, we must go straight to stay and stay, and cultivate them into fruiting branches. By retraction, the growth potential of the shoots is enhanced, and the purpose of updating the rejuvenation results is achieved.
Third, short cuts. The short cut is to cut a part of the shoot. The purpose of the short cut is to increase the branch volume and leaf area of ​​hawthorn, promote growth and rejuvenation, adjust the main branch, and maintain balance so as to facilitate the production and accumulation of nutrients. According to the difference in the degree of cutting, it can be divided into light and short cuts, short cuts and heavy cuts. For the long branches of the main branch extensions and indwelling branches, appropriate short cuts should be made to increase the number of development branches so that the resulting branches and development branches can maintain a proper ratio and prevent the occurrence of top-down phenomenon. Peripheral shoots with a length of 30 to 40 cm can be shortened by about 1/3.
Fourth, training. It refers to the cultivation of a new canopy of hawthorn trees in a debilitating period and timely major updates. Perennial large mountain banyan trees, treetops Jiaozuo old decay, internal emptiness, should be gradually cultivated branches (ie leggy branches) instead of updating the original crown, or in the tree pods using leggy branches to cultivate the results of Zhizu. In order to cultivate the result sticks, we can adopt the method that emphasizes first and then lightly, that is, re-twisting the buddhist branches to initiate branching, and then go upright and stay flat. Through cultivation, internal hemorrhoids can be enriched, the resulting area can be expanded, and production can be restored.
