First, the purpose of trimming cherry tree during the aging period significantly weakened, fruit production and quality decreased significantly, should be updated in a timely manner. Second, the pruning method usually utilizes the developmental branch that is formed by the base of the stem branches, and the branches with short branches to plan and update the branch branches, restore the tree vigor, rejuvenate the result branches, and prolong the economic life. When the tree vigor is seriously weakened, major updates of the backbone should be made. The benefit of the big update is that it has a large number of branches and a strong branching force. In the new year, with the summer topping, the canopy can be restored quickly, with early results. In the second year of the renewal, depending on the strength of the tree-trend, the slow release will be the main factor, and the remaining branches will be selected appropriately. Third, the matters needing attention Winter updates easily make the cherry tree's branching force, germination rate significantly reduced. Therefore, the renewal time is good for early spring budding. When the backbone shoots are updated, the length of the pile should be short, 30-40 cm in length, and no more than 50 cm. If the pile is too high, the branching ability is weak, and the updating effect is not good.
