Points for attention in planting cherry trees in summer

First, pick the heart. Its purpose is to control the growth of branches, increase the number and grade of branches, promote the transformation of branches, and expand the crown. This measure is mainly used on young and prosperous trees. The best time for coring is the rapid growth period of new shoots, when the length of new shoots is about 20-25 cm, just take off the tender shoots at the top. If the tree is exuberant, the secondary tip after picking the heart is still very prosperous, and you can also pick the heart for the second or third time. Coring at the right time is an effective measure to promote early fruiting and early high yield of young cherry trees.

Second, pull branches. The purpose of pulling branches is to adjust the angle of backbone branches or auxiliary branches, ease the tree potential and promote early fruit. Branching is carried out after the beginning of spring or after fruit harvest in June. After a growing season, the angle is basically fixed, and then the rope is untied. When pulling the branch, we should pay attention to prevent the big branch from splitting, and also prevent the support point of the pulling branch from being too high and the middle of the pulled branch arching upward, resulting in a small waist angle or strip phenomenon.

Third, thinning branches and retraction after fruit harvest. After cherry harvest, pruning should be carried out in order to adjust the tree structure and improve the ventilation and light transmission in the crown. The main pruning methods are thinning and retraction. The strong and strong branches which seriously affect the ventilation and light transmission in the crown and have no retention value can be removed from the base, and the large branches which only affect the local light of the crown but have certain fruiting ability can be shrunk at the larger branches with larger branch angle and growth ability. in the specific treatment, the low-grade branches can be shrunk, and the high-grade branches can be thinned.

In addition, when the new shoots were not lignified from late May to early June, the upright branches, competitive branches and introverted erect branches were twisted to facilitate the formation of flower buds and lay a good foundation for high quality and high yield next year.
