First, the benefits of long branch pruning. Pruning of long branches of peach trees is based on pruning and long-distance pruning methods. Compared with traditional pruning, which is mainly based on short cuts, it has the following advantages. 1, significantly increase early production. Pruning long branches before young fruiting stage can significantly reduce the growth of new shoots, reduce the percentage of shoots and branches, accelerate the transformation of branches, increase the total branch amount, and ease the tree vigor. 1- Two years into the result period and full fruit period can significantly increase early production. 2. Significantly improve fruit quality. Long branching leaves a relatively small amount of pruning, only 50-60% of the traditional pruning, can significantly improve the ventilation and light conditions of the tree, improve the nutrient level of the tree, and thus significantly improve the quality of the fruit. According to tests, long branch pruning can make fruit coloring 7-10 days earlier, increase color fruit rate and total red fruit rate by 20% and 30% respectively, and increase fruit soluble solids content by 1.5-2%; at the same time, it can significantly increase fruit setting rate. . 3, simple technology. Long branch pruning technology is simple, easy to grasp, can significantly reduce the amount of pruning labor, improve labor productivity. Second, long branch pruning technology points 1, to extend the head of pruning. The opening angle of the main branch should be maintained at about 60 degrees and the lateral branches should be 70-80 degrees. The extension of the saplings is accompanied by a prolongation of the extension of the headband; the lengthening of the adult tree, the elimination of part of the auxiliary shoots in Wangshu, the compression of the golden mean tree to the strong auxiliary tip, and the extension of the weak tree with the small clam. 2, the results of the pruning. During winter cutting, the lengthy branches with the length of more than 60 cm, the buds with the auxiliary tip, and the weak branches with less than 30 cm, and the branches with pests and diseases must all be removed, and the robust branches with the length of 30-60 cm should be kept. A long fruiting branch is reserved every 15-20 cm on the backbone branch and the large branch group, and the total amount of the total branch branch is 50-60% of the conventional pruning (ie, short branch pruning) method. The crowns of upright canopy varieties were selected to retain the horizontal branches of upward oblique shoots. The upper part of the canopy can be appropriately selected to leave downward oblique shoots and dorsal branches. The fruiting branches of the open canopy of the crown can be selected to retain the upward oblique branches, while the upper part of the crown can retain some horizontal branches. The lower part of the canopy can be left with a small amount of back branches. Long-term or light-short cuts are reserved for long-fruiting branches that have been preserved. Fruits are kept in the middle and upper parts of the jubilee. Fruit branches will be sagging under pressure or through litchi and twigs. The robust shoots from the base of the fruit branches were cultivated as renewed shoots and the remaining shoots were wiped out as soon as possible. When the winter cuts, the resulting branches are removed, and the branches are replaced. 3. Precautions (1) The position of the 1-year-old branches on the backbone should be kept as close as possible to the branch axis to reduce the number of branches. When possible, shoots are updated and cultured using new shoots from the base of branches or the bases of perennial branches. (2) Pruning of long branches is suitable for use in species that are dominated by long fruiting branches, such as southern varieties, trees before full fruiting period, and trees with prosperous growth. For fruit varieties (northern cultivars) with short fruit branches (including fruit-bearing fruit branches), the three branch renewal method is suitable for pruning in the full fruit period, ie, a short and short cut result; one long shoot leads to short branches; the other branch Two buds of the residing basal leaves are replanted to prepare the mother shoots and promote development and development. In the winter of the following year, the fruiting branches were removed, the branches were lightly cut, the branches were put in light, and the results of several short branches with high quality were selected; the two development branches that had been grown on the mother stand were put in one long and one cut, which resulted in turns. (3) The long branch pruning is mainly based on thinning and long-distance divergence, which will ease or even weaken the tree potential. Therefore, management should be strengthened. In particular, it is necessary to strengthen soil fertilizer and water management and flower and fruit management (strict sparse flowering and fruit thinning, and reasonable load). In summer, pruning (wiping up buds, removing competing branches, leggings, etc.) enables the long fruiting branches to produce strong and long branches at the same time as results, so as to maintain the long fruit branch's continuous fruit ability and robust tree vigor.
