After the apple tree was grafted and changed to survive, the scions were numerous and prosperous and upright. The result was similar to that of saplings, that is, they depended mainly on the results of medium, long fruiting branches or pod buds. The pruning method was:
1. Open the backbone to extend the branch angle. Extension points tend to be vertically upwards, and branches are thick and hard and should be controlled in time. Open the angle to 80 ~ 90 degrees, so that its horizontal straight line extension; if it can not pull open, you can use a large angle of the next new shoot or lateral branch generation, and the original head is strictly controlled or weakened.
2. Light long cuts. In addition to the backbone branches, all kinds of branches and auxiliary branches should be as long as possible to cut long, put more branches, leave more flower buds, and have appropriate development branches with short development space to quickly restore the canopy.
3. Culture sticks. Mostly use the first shrink method.
4. Strengthen summer cuts. The method of girdling, ring cutting, tipping, and pulling branches for the auxiliary branches and large branch groups can produce large numbers of flowers and bring about early results. Take torsional shoots, twigs, pull branches, etc. on the competition branches to increase the result area and improve the illumination of the internal crucible, and cut off the sprouting around the interface at any time.
5. Control tree height to improve lighting. The leader of the Central Committee should not let it rise freely, and should be controlled at an appropriate height (3 to 3.5 meters). At the same time, the dense tree branches should be removed and retracted to solve the problem of internal light.
