The apple tree topping leaves can control the growth of branches and promote flowering, but some fruit growers only scratch the heart and go to the wrong leaves. Topping the leaves to the following points: First, it is not appropriate to engage in the weak tree to pick the heart to the leaves. Weak trees have weak photosynthetic activity and cannot guarantee their own lives. The more they engage in picking their hearts and go to the leaves, the more they will reduce the nutrients in the tree and cause the declining tree vigor. At the same time, it will also cause many diseases, such as yellow leaves and small leaves. Illness and so on. Second, do not take off and not pick it up. Some fruit growers do not understand the truth of taking care of the leaves and blindly chaos. When picking the leaves, it is not the tender tips with gibberellin on the top of the branches. Instead, several old leaves in the lower part of the branches were mistakenly removed, and the tip leaves did not move at all, resulting in counter-productive effects. Third, do not take too much to take care of the leaves. Topping the leaves is to remove four or five pieces of yellow leaves that contain more gibberellin, but it is not appropriate to pick too much. Some fruit growers pick too many leaves, which will affect the photosynthesis of branches. Accumulation of nutrients cannot result in flowers. Fourth, do not go too late. The best time to take the heart to the leaves is before each physiological stop of the fruit tree, so that it is easy to form flower buds. Some people have taken it to the leaf at a time when the new shoots are growing vigorously. As a result, they soon grew up with tender tips, which cost a lot of work and the effect is not good.
