How many ways to prune peach trees in summer?

How many methods are there to prune peach trees in summer? Please introduce the summer pruning of peach trees for the following reference: 1. Wipe the buds. The sprouting tillers within 15 cm of the trunk, the shaping belt of the main branch and the parallel and overlapping buds and shoots of the main branch should be erased or cut off in time, so as not to affect the growth of the backbone branch. two。 Pick the heart. When the new shoot grows to 30 cm long, pick the tender shoot at the apex and stop it from extending forward, forcing the nutrients to turn to the lateral buds, stimulating the sprouting shoots and reducing the branches. In this way, it can not only control the vigorous growth, avoid the formation of "long umbrella" branches, but also create conditions for the culture of fruiting branches, but also promote fruit development and flower bud distribution. Coring and pruning should be 30 cm long, not too long or too short. Too long, the lower part of the bald segment is long; too short, it is easy to stimulate a large number of shoots in the lower part. Those who are less than 30 centimeters long do not pick the heart, and those that have been capped and stop growing do not pick the heart. 3. Trim the ends. The new shoots that are too dense, improper orientation or failed to pick the heart in time are thinned or cut short by 30 cm in length, so as to adjust the growth, angle and orientation of backbone branches, control overgrown branches and competitive branches, and reduce invalid growth. so as to achieve the purpose of suppressing the strong and supporting the weak, enriching the inner chamber and balancing the tree potential. 4. Qu Zhi. For upright and strong new shoots, 10-15 cm from the base, the lower part is fixed with the left hand, and the upper part is gently kneaded with the right hand. After the wood is soft, the upper end is bent to the gap, making it flat or sagging, and changing the branch growth direction is used to ease the apical dominance, so that the upper part forms flower buds and the lower part germinates secondary shoots, which creates conditions for the culture of fruiting branches. But kneading efforts should be light and uniform, must not be too heavy, try to avoid breaking wood or breaking the skin, causing glue flow and weakening the tree potential. 5. The opening angle, balance the tree potential. For the varieties with upright tree and small angle of main branch, the opening angle is opened by means of brace, pull, back, fall and so on. If the orientation of the extension of the main branch is unreasonable, it shall be adjusted by the method of "back branch" or "turning the main head". If the growth of the main branch is unbalanced, the methods of strong branches with less renewal and more flower buds and more fruit are used to reduce the branches and inhibit the vegetative growth, while the weak branches with more regeneration and less flower buds are used to promote the multiple branches and enhance the vegetative growth, so that it can reach a balance year by year. 6. Spray growth regulators. From late May to June and early August, the fruit trees with prosperous growth were sprayed with PBO accelerator 200,300 times, and pay attention to not watering within one week after spraying, which can not only control the vigorous growth, promote flower bud formation, but also promote fruit growth and prevent fruit cracking. Fruitless trees can be sprayed with paclobutrazol 200 times to inhibit shoot growth and promote flower bud formation. Peach trees should not be ring-peeled and ring-cut when cutting in summer, otherwise it will cause glue flow from the wound.
