The growth characteristics of the aging apple trees are that the growth rate of new shoots is small, there are many shoots, there are many flower buds, but the results are few. The twigs in the inner twigs are dry and dead, the result is obviously moved, the bald lamellae are bald, and the middle and lower parts of the shoots grow more leggy. branch. The pruning management of such aging trees is mainly the update of rejuvenation. 1, retraction update. When the main and lateral branches are retracted, the angle of selection is smaller, the back branches that grow more prosperous, and the standing Wang branches instead of the original head, enhance the tree vigor. 2. Branches must be retracted. For all types of branches, it is necessary to appropriately cut, cut more, reduce vegetables, and raise the angle. The principle of pruning is to keep straight, stay strong, stay strong, and stay long. Sparsely dense fruit and short fruit branches, retain and rejuvenate back, anticline, short axis strong branches. 3, conducive to long-term update rejuvenation. The use of leggy branches is an important measure to update rejuvenation. It is necessary to distinguish between different situations, rationalize the reforms, and focus on training. Using a combination of multiple methods, such as leggings and erection, erecting branches and branches, promotes branching and enhances growth potential. 4, to minimize the level. In the structure of the tree, we should adopt the method of retraction and drop the head to minimize the level, reduce the height of the tree, increase the illumination of the internal beam, and obtain the updated robust branches at all levels. 5. The renewal of the aging period is early. Some apple trees need to be partially updated from the later stage of fruit production, and they must strengthen fertilizer and water management. They should be rotated and updated on a tree year-by-year in order to facilitate the cultivation of assimilation and active roots. Prevent one-time full tree rejuvenation during extreme aging.
