What are the pruning methods for big cherry trees in summer? Please introduce the pruning method of big cherry in summer pruning is best carried out when the branches are not fully lignified after harvest, the main methods are pruning, coring, pruning, thinning, ring peeling and so on. First, pull branches. Winter pruning can not solve the ventilation and light transmission conditions of the tree at one time. If some big trees put too much emphasis on the angle in winter pruning, they are bound to be cut off, causing unnecessary losses to the tree. In summer, the problem that can not be solved by winter shearing can be solved by pulling branches, in order to reduce the amount of thinning branches, at this time, the reaction of the tree is relatively mild, it is not easy to shoot on the back, the angle of the main branch and side branch should be 60-70 degrees, and other branches can be pulled to 80-90 degrees. Second, pick the heart and cut the tip. Coring refers to the removal of the young part of the tip before the shoot hardens. The coring of young and prosperous trees of big cherry can control the vigorous growth of branches, increase the number of branches and branches, promote the transformation of branches, accelerate the expansion of tree crown, save nutrients, promote flower bud formation, and improve fruit yield and quality. Pruning refers to cutting off part of the new shoot, mainly when the new shoot can no longer pick the heart or to expand the crown. Because the pruning degree is greater than that of coring, the effect of pruning is stronger than that of coring. Third, thinning branches. In summer, branch thinning is usually carried out after fruit picking, and its purpose is to remove the perennial branches which are too dense, too strong and seriously affect the light, so as to improve the ventilation and light transmission condition of the inner chamber of the crown, balance the tree potential, and it is easy to heal the thinning wound after fruit picking. Fourth, girdling. Girdling of big cherry trees can promote flower bud formation, improve flower fruit setting rate and fruit quality, especially on pulp firmness and sugar content. However, after the ring peeling of the big cherry tree, the wound heals slowly, pay attention to the width of the ring peeling not more than 0.5 cm, and because the tree potential of the big cherry is different, especially the trees with less organic fertilizer, it is easy to appear the phenomenon of glue flow, so it should be used cautiously in production and apply again after accumulating some experience.
