The main branch of the peach tree with two main Y-shaped branches has only a few branches. Only 2 can be selected. The canopy has good ventilation and light transmission and is suitable for dense planting. The result of the tree has more branches and fruiting branches. Since it is a dense plant, it is generally not cultivated. Large-scale branch and lateral branch, all kinds of branches directly on the main branch, distributed around the main branch, mainly on both sides. After forming, the entire tree can produce 60 to 80 branches of varying sizes. The height of the tree is 2.5 to 3.0 meters; the angle between the two main branches is 60 to 70 degrees, and the opening angle is small, which is convenient for mechanized operation. The following points should be mastered for the cultivation of this tree. 1. The two main branches of young trees are shaped. The saplings are mainly tree-cultured, stem-height 30-50 cm, and dry height 60-80 cm. Select two branches with good growth potential, full shoot buds, and positive direction to make two main branches. Fix the angle of the main branch to 45 to 50 degrees by branching, pulling, and falling. In winter, special emphasis must be placed on four details: (1) Extend the branch treatment: Weak branch weights should be short, middle tree branches should be strong, and strong branches should be thrown away. (2) Branches near branches: Disposal of competitive branches, leggy branches, and dense branches. (3) Correcting the direction of the branches: The direction of the branches is not correct, and the neighboring branches that have a promising direction of correction can be used for replacement. (4) The growth of the two main branches requires that the two main branches grow in balance, the main branches have a strong tree vigor, and can leave weak branches to change heads, leaving more fruits and leaving more branches; the main branches have weaker tree vigor, and can be used to replace heads with strong ones. Leave fruit, leaving fewer branches. 2. Reasonably locate the result set. No branchlets were left on the main branch, only the resulting branch groups were cultured, and 9 to 11 branch groups were cultured on each main branch, and the cross-corresponding arrangements were evenly distributed on both sides of the main branch, 40 to 50 cm apart. Until the full fruit period, if the branches are too dense, some branches may be removed. All branch groups were cultured from dorsal branches of the dorsal aspect, forming an angle of 60 to 70 degrees with the main branch. At the base of the main branch, the large branch group was cultured, and the medium branch group at the middle level was closer to the extension head. The smaller the branch group was, the closer to the extension head was, leaving only the result branch. 3. Balance the distribution of results. Results The results showed that the branches were left on the branch and the branch spacing was 15-30 cm, leaving a diameter of 0.6 cm and a length of 20-60 cm. 5 to 6 can be left on the large branch group, 3 to 4 on the middle branch group, and 1 to 2 on the branchlets group. The gap between branches and branches can leave short fruit branches and bouquet-like fruit branches. 4. Update the results in time. The fruiting branches of fruit trees in the fruit period weaken after the results and need to be updated in time. As a result, the branch update method may leave a reserve branch update or leave no reserve branch update. Without leaving an update of the preparation branch, it is also called a single branch update. When pruning, it is appropriate to increase the length of the fruit branch. Keeping the preparation branches updated, also known as the two branches update, pruning, that is selected on the same mother branch adjacent to the base of the two results of the branches, the upper branch light to stay long for the results of the branch, the lower branch to stay 2 to 3 section cut The result is that the following year will not produce results, which will enable them to pick up their talents and prepare for the next year. The branches that are cut down are ready branches. In the next year's results, the finished branch is cut off, and the two new shoots that occurred in the preparation branch will be produced as the result of the upper branch and the lower one as the reserve branch. Such an annual update, so that the results of the site is not far away from the big branch, can rejuvenate the branch group.
