Pruning peach trees: 1. Modeling, potted ornamental peach trees have straight trunk shape and curved trunk shape, and the straight trunk shape has one main branch curve shape, two main branches antlers shape, three main branches happy shape, trunk shape and Y shape. When the happy tree with three main branches grows to 30 cm, two buds are selected from both sides at 10 cm, and then the upper branches of the buds are drawn horizontally, so that the buds on both sides will germinate quickly to form a happy tree with three main branches. When the new branches grow to 20 cm, pick the buds and pull the branches horizontally to promote the secondary germination. If an upright branch grows on a flat branch, the base can be cut off to prevent it from growing in vain. The flattened new branches and old branches are pulled out before June 20 to promote the development of secondary branches, and flower buds can be formed that year. The trunk shape was put forward by Kazuo Shimamura of Japan, that is, there is a fruiting branch group on the trunk of the central leadership, and there is no main lateral branch. The height of potted ornamental peaches should be short and the number of branches can be small. Generally, the height is within 1 m, and the branch spacing is 15 ~ 20 cm. In the first half of April, pay attention to wiping buds and strengthening buds. From mid-May to early June, the erect branches, overgrown branches and overgrown branches in the crown are cut off. In mid-July, some new buds will be distorted, and over-dense secondary buds will be eliminated. For trees with vigorous growth, apply 2g paclobutrazol 1 m2 in the rhizosphere to control the growth. In the middle and late September, the dense branches, upright branches and branches with low planting position are thinned again. In this way, 5 ~ 6 fruiting branches grow on the trunk, and they extend uniaxially without bifurcation. The peach trees in the nature reserve are all Y-shaped, with a dry height of 20 cm. The branching angle of the two main branches is 45-50 degrees, and the angle between the two main branches is 90- 100 degrees. The main branch does not have side branches, but some branchlets are used. The height of the tree should be controlled at about1~1.2m.. The antlers of the two main branches are similar to Y-shape, but the angle of the main branches is slightly smaller. There is a small uniaxial branching group, such as antlers, on the upper part of the main branch.

The bending shape of the main branch is formed by binding the branches with lead wires, the thickness of which is 1/3 of the thickest part of the bound branches, and the length is 1.5 times of the length of the branches. Tie the trunk first, then the main branch, then the side branch, from bottom to top, from thick to thin. When tying the trunk, insert the end of the metal wire into the bottom of the basin and fix it on the soil. The place where the wire is inserted is at the back of the trunk, so that the wire will not be exposed. Peach trees are thin and easy to flow. Before binding the wire, wrap the wire outside to avoid hurting the bark. The winding lead makes an angle of 45 degrees with the branch diameter, which can be clockwise or counterclockwise. Lead wire should be close to bark, not too loose. When winding at the branch end, the lead wire head should be close to the bark and not protrude. After the wires are wound, the branches can be bent, and at the same time, the wires can be slightly twisted along the winding direction, so that the wires can always lean against the bark without loosening. Peach trees grow rapidly, and lead wires can be removed in about 3 ~ 4 months. Then, according to the requirements of modeling, the branches are rearranged to make the tree shape conform to the author's intention. Curved stems are mostly used to shape roots, which can be shaped into animals such as antlers, cocks, trotters, unicorns, cranes and monkeys, as well as bonsai forms such as black dragons exploring the sea, larks in the forest, green leaves flying, dragons soaring in the clouds, dependence, emergence and bloom.
