1. Regulating growth pruning method
1. Regulate the strength of growth. In terms of period, to strengthen growth, winter should be heavy in summer, and winter should be cut in advance. On the contrary, winter is lighter than summer, and winter cut is delayed. In terms of measures, to strengthen growth, the branches should be reduced under the premise of making full use of space, weak and strong, flat and straight, fewer fruit branches, elevated buds, and reduced damage. From a local and overall perspective, strengthening local growth should weaken the growth of other parts. For example, controlling the upper can promote the lower, and controlling the strong can promote the weak. In addition, growth regulators can be used, GA for strengthening growth, and B9 and plastic elements for weakening growth.
2. Adjust the angle of branches. Expanding the angle can choose the open branches and buds, which can be pulled, supported, dropped, twisted by external force, and can also use the weight of the fruit branches, leaves, and fruits to fall by themselves. To reduce the angle, the buds on the back are generally selected as cut-out buds, with little or no fruit on the top of the branches; for heads, upright branches are used instead of the original ones.
3. Adjust the density of branches. Increasing the branch tip density can keep the branches as far as possible. You can increase the branches by pinching, cutting, etc.; it can also be shortened to increase the branch tip density. In addition, plastics, cytokinins and other chemical agents can also be used. Measures such as thinning branches and long release can be adopted to reduce the density of branch tips.
2. Adjust the pruning method of flowers and fruits
Increasing the amount of flower buds generally takes a wide angle to accumulate nutrients and promote flower bud differentiation; saplings should be lightly cut, slowly released, twisted, pulled, and applied growth regulators to promote bud differentiation on the basis of ensuring normal growth and appropriate branch and leaf quantity. . To reduce the amount of flower buds, cut is generally heavy, winter is heavy and summer is light. GA etc. are used to strengthen tree vigor, promote the growth of branches and reduce flower bud differentiation.
Measures to preserve flowers and fruits: maintain a reasonable number and proportion of various organs according to the high yield index; improve the light after stopping the shoots to enrich the shoots; select the best to remove the inferior, and retain the strong branches and flower buds.
