How to prune apple trees in summer? Please introduce the method of summer pruning, also known as growing pruning, which is one of the important parts of annual pruning of apple trees, and plays an important role in annual pruning of apple trees. the main pruning methods are ring cutting, ring peeling, twisting, coring, branch pulling, branch thinning and wearing a hat in autumn. However, improper pruning will have a bad impact on fruit trees, so summer pruning must follow the following five principles: objects should make it clear that the main objects of summer pruning are laissez-faire growing trees, young and prosperous trees, and age-appropriate non-fruiting trees. Trees that are difficult to bear fruit and trees that are too weak generally do not prune in summer. The time should be suitable for summer pruning and seize the opportunity. Miss the opportunity not only can not achieve good results, sometimes there will be the opposite result. In general, the effect of circumcision and girdling is the best from late May to early June. Coring and twisting should be carried out from late May to early July. Pulling branches and thinning branches were better during the period from the Beginning of Autumn to White Dew. It is better to wear a hat and cut it in the first and middle of August. The amount of pruning should be appropriate because summer pruning will hurt or cut off some branches and leaves, which will reduce the photosynthetic area and weaken the growth potential of fruit trees. Therefore, the amount of pruning should be lighter, cut as lightly as possible under the premise of improving ventilation and light transmission, so as not to stimulate vigorous growth or excessively weaken the tree potential, so as not to adversely affect the growth and fruit of the tree. In order to promote flower bud differentiation and improve fruit quality, we should pay attention to improve the crown microclimate, ensure good ventilation and light transmission conditions, after cutting, the branches are dense and moderate, the arrangement is uniform and reasonable, and the light can be transmitted to the inner chamber and the lower layer, so as to achieve the purpose of promoting flower bud differentiation, avoiding "big and small years" and improving fruit quality. According to the local conditions, according to the tree age, tree potential, variety characteristics, natural conditions, pruning purpose, etc., we should determine the suitable pruning method and pruning degree, or promote flower and fruit, or promote growth and potential, or improve the quality of fruit, so as to achieve the goal of high quality, high yield, stable yield and strong tree.
