Peach trees generally need 3-5 times in summer all year round, and the key pruning time is concentrated in May-August. The main pruning methods are budding, coring, twisting, thinning, slightly pruning, pulling and so on. How many times to prune and which pruning method to choose can be flexibly grasped according to the situation of the orchard.
First, the bud of summer scissors
1, new bud erasure: After the peach tree germinates, you can erase those buds on the back, the dense buds, and the inappropriate buds in time.
2, new slightly smooth: when the new slightly about 5 cm long, but also in a timely manner to remove the invalid tender slightly. If it is a double omission, it should be erased according to the angle; When wiping the buds on the trunk branches, the new buds that are cut and sawed and within the range of 15 cm from the base of the trunk branches should also be wiped flat in time.
Second, the heart of summer scissors
Peach trees are growing too vigorously. When the length is about 20 cm, it can be topped and cored, and when the new core is 30 cm long, it can be twisted again to promote the growth of lateral branches.
Because peach trees are more likely to shoot a large number of new auxiliary branches after stone removal, if not handled in time, it will easily lead to dense branches and closed crowns. Therefore, except for pruning young trees, it is not recommended to carry out coring treatment on other peach trees.
Third, the torsion of scissors in summer.
Peach tree tip twisting is mainly aimed at the elongated branches of the main branches, the newly grown flourishing branches in the upper part of the crown and the strong branches near the short nodes in winter, which can be carried out when the flourishing branches are 25-30 cm long and the branches are just semi-lignified; When twisting the tip, hold the base of the new branch 5- 15 cm by hand, and twist 180 degrees to make the branch droop slightly or grow obliquely to control the flourishing length.
Fourth, summer pruning
Peach trees can be thinned when they grow to about 30 cm. According to the position, thickness and growth of new trees, select strong branches and strong branches with reasonable positions, and remove those branches that grow too vigorously, too densely, too finely, vertically droop and compete. For the overgrown branches in the upper part and periphery of the crown, the control treatment should be carried out according to the principle of removing the strength and leaving the weakness, so as to improve the light-passing environment of the crown and promote the germination of peach blossoms.
Five, cut a little in summer.
Pruning can be carried out after the peach trees have fallen flowers, with 1 bud remaining on the young fruits, 3 buds remaining on the middle and long branches that failed to blossom, and 1-2 nodes remaining on the main branches and new branches clustered in the crown for super-pruning.
Sixth, scissors pull branches in summer.
Pulling out branches on those young trees with luxuriant leaves can relieve the tree vigor, shape the ideal tree type and promote the young trees to bear fruit early. For the main lateral branches with small angle and direction deviation, as well as the large fruiting branches with upright position, branches can be pulled, and the angle of branch pulling is generally about 80 degrees, but branches cannot be pulled horizontally or droopingly.
