Red star marshal system apple can be based on the above characteristics of the following pruning methods.

Crown shaping, the arrangement of main and lateral branches should be "adjacent", should not be "adjacent", in order to prevent the "neck" seriously weakened the growth of its central branch axis, affecting the upper Cultivation of backbone branches, the future caused by the "lower strong on the weak" unbalanced phenomenon. The extension of the backbone branches of the head should be "in the bud outside the stirrup" or "double bud outside the stirrup" method to cultivate the second bud under the cut or the third bud branch, and pay attention to the growing season opening angle.

The young prosperous tree should pay attention to more light pruning slow release and winter, summer shear combined with continuous control of branching potential pruning techniques to promote the development of short and medium branches as soon as possible into flowers and results. In the specific measures to use more open, thinning, slow, curved, injured and other methods, that is, open the backbone branches, thinning dense crowded branches, slow release flat slanting branches, curved injury straight prosperous branches. As little as possible with the method of short cuts to prevent the advent of strips, affecting the results of flowers.

The cultivation of fruit-bearing branches can be put first and then shrunk, first control and then put and then shrunk and continuous super-heavy truncation method. In the position of more training in the backbone branches on both sides and under the back. On the back of the upright large top bud conical development branch can be broken or hit the head, promote the development of short and medium branches. For many years alone and no flower buds of a single branch can be used "hat" pruning, the strong "live hat", the weak "dead hat". Next year, according to the branching situation can also retract the head branch, and then again on the "braided branch" at the base of the super heavy cut "wearing a crooked hat". The two branches can be cut off a slow one. The three branches can go to the center to stay on both sides. The slender and weak string of flowering branches can be retracted in half, and then use the method of broken flower buds every other broken one, "flower for flower". The weak fruit platform branch group can be retracted to the lower branches. The bare fruit platform without fruit platform branch can break the platform cut, promote the development of new shoots (Figure 49 ⑤).
