1, pruning and shaping of young fruit trees. At present, dwarf and high-yield cultivation techniques are adopted in production, and young fruit trees are mainly cultivated in tree shape. Evergreen fruit trees are cultivated by thinning branches, so that the fruit trees are ventilated and evenly distributed; Deciduous fruit trees such as peaches, plums and pears often adopt Y-shaped and cup-shaped trees, while pear trees adopt inverted herringbone branches or double hedges.

2. Pruning and shaping of adult fruit trees. Prune the fruit after picking, and cut off the diseased branches, residual branches, dead branches and weak branches with fruit scissors. Pruning in winter: Deciduous fruit trees enter dormancy and begin pruning. Pruning of evergreen fruit trees will be carried out before the spring shoots are pulled out and the old leaves fall off at most.
