How to plant peach trees?

How should peach trees be trimmed? what are the requirements? Peach trees have the following five technical points: the pruning technique of ⑴ balance tree potential. In shaping and pruning, the growth imbalance between backbone branches is often encountered, the space can not be fully utilized, and the yield per plant is low. At this time, a variety of means are used to suppress the strong and help the weak to achieve the goal of balanced growth. In general, heavy pruning of strong branches, light pruning of weak branches, weak buds of strong branches, more fruit of strong branches, less fruit of weak branches, opening angle of strong branches and raising angle of weak branches are generally required during pruning, by means of brace, pull and droop, combined with fertilization to gradually balance the tree potential. ⑵ tree pruning techniques to promote fruit. For this kind of trees, in addition to fertilizer and water control and chemical control, reasonable pruning should be carried out. First of all, open the light path, remove some of the backbone branches and shading branches, especially the long branches on the back, to open the angle of the main branches, where there is light, there are flowers. We should also pay attention to the methods of picking and picking Wangzhi in summer. Winter pruning can also be changed after early spring to weaken its growth. In this way, the tree potential can be relaxed in 1-2 years, full flower buds can be formed and the yield can be stable. Pruning of ⑶ fruiting branches. The number of fruiting branches is related to variety, tree potential, tree age and so on. Generally, the distance between branches of fruiting branches is kept at 10-20 cm after pruning in winter. The varieties of the northern variety group are mainly short fruit branches, which can be denser appropriately, while the varieties of the southern variety group are mainly medium and long fruit branches, which can be thinner. Results the retention length of branch shears should be determined according to the length of branches, the position of bearing, the fruit setting rate of varieties and so on. In general, long fruit branches leave 5-8 flower buds, when they are too dense, remove erect branches and leave flat oblique branches, pay attention to the distribution of branches not to be "uniform" and stagger in length, but also pay attention to reserve branches, middle fruit branches generally leave 3-5 flower buds, cutting buds leave leaf buds Short fruit branches and flower-like fruit-bearing branches are generally sparse but not cut, and the fruit-setting rate of futile fruit-bearing branches is low and the growth is prosperous. After short-cutting, several good fruit-bearing branches can be produced, which are often combined with summer pruning and cultured into fruit-bearing branches. The culture of ⑷ fruiting branch group. The fruiting branch group is a fruiting unit composed of several fruiting branches directly planted on the backbone branches, and it is also the main part of the fruit yield of the tree. There are three kinds of branch groups: large, medium and small. The large branch group has strong growth potential and long life. The fruit is of good quality. The culture method is as follows: generally, 5-10 nodes are left for the more prosperous branches, 2-3 strong branches are left in the lower part in the second year, the other branches are thinned, and 3-5 buds are cut short in the third year, which can be cultured into large fruiting branches. The large fruiting branch group is generally distributed on the oblique side of the backbone branch, while the medium and small branch groups are distributed on the back and in the space of the large branch group. The culture method of small and medium-sized branch group is similar to that of large branch group, but the control is smaller. Pruning and updating of ⑸ fruiting branch group. The pruning fruiting branch group should pay attention to the growth and density of the fruit branch, not only consider the fruit of the current year, but also prepare the fruit branch of the next year, the strong branch can keep more fruit, the weak branch can be re-cut and renewed, so as to ensure the stability of the branch group. if the branch group is weak, it should be retracted in time for intra-group renewal, re-pruning and developing branches should leave more lower reserve branches, less fruit, and gradually recover. Some branch groups are old and can be thinned and replaced by nearby new branch culture, or other branch groups can be extended to this space. If the branch group is strong and prosperous, it is necessary to remove the strong branches and erect branches in time, and leave the moderate and strong fruiting branches. In branch group pruning, there are two ways to cultivate preparatory branches, one is called double-branch regeneration, that is, two similar fruit branches are selected on the mother branch, the upper branch is pruned according to the fruit branch, and the lower branch is re-cut only by the two buds at the base, and two new shoots are produced to form the knot of the second year. In winter, the upper fruiting branches will be thinned off, and the lower new and two branches will still bear fruit according to the method of the previous year, and the upper branches will bear fruit, and the lower branches will be cut short, so that one fruit will be produced and one branch will be drawn every year. There is also a kind of single branch renewal, that is, the medium and long fruit branches are properly re-cut, so that they can not only bear 2-3 fruits, but also pull out strong new shoots, and remove the upper branchlets in winter, while the robust new shoots in the lower part are also heavily cut, so repeatedly to maintain the results.
