Plants that grow and bloom more flowers, the result of branch pruning should be weak and strong. The overly sleazy branch group should be shortened and cut off, and the diseased branches and dead branches should be cut off to increase the light transmission and permeability of the crown. For plants that grow robustly but have less flowering, some of the weak branches can be deleted, and a small number of dense branches can be selected for shortening. Plants that grow robustly but have more flowers should be cut off from the results of the harvested fruit; the new shoots that are germinated after shortening in the spring should be strong and weak, so that one or two new shoots can be retained on each branch. For flowers without flowers or basically without flowers, they should be re-cut in the spring, not for summer shears. The pruned fruit trees should be protected accordingly. The small pruning mouth can be applied to the callus anti-corrosion film to promote the wound healing. The large pruning mouth can be coated with new high-fat film mother liquor to prevent wound oxidation and prevent wound infection.
