Retraction creates injury, slowing down the front and promoting the rear. For strong branches with upper shoots and lower weak or bare legs, retract strong branches after opening angle, thin back upper branches, and implement multiple ring cutting in middle and lower parts before germination to promote new branches, and slow release for weak upper branches, back lower branches and both lateral branches. There are many branches on the back of the main branch, so we should go straight and stay flat, go strong and stay weak, and control the branches by taking branches and other methods to ease the tree momentum and promote the formation of flower buds. 3.
