After many years of fruit bearing, the branches grow thin and messy, the crown is closed, and the ventilation and light transmission conditions are not good, which is not conducive to nutrient supply and new shoot growth, and affects flower bud differentiation and yield improvement. Therefore, before fruit trees germinate, they should be pruned at the latest before the vernal equinox. Cut off dead branches, pests and diseases and unused branches; Sparse competitive branches and overcrowded branches. Pruning young fruit trees; The emphasis is on fruit tree retraction and pruning. Stick a new high-fat film on the incision to protect the wound and promote healing and growth. Promote the robust growth of fruit trees.

Winter scissors

① Look at the age of trees: the pruning amount of young trees and first-bearing trees should be small, and the pruning degree should be light. Pay attention to cultivating tree types and bearing branches; Trees should be re-cut properly during the full fruit period, and pay attention to the rotation of fruiting branches; Re-cut down trees and renew fruiting branches during the aging period.

② Look at the number of flower buds: Fruit trees with large flower buds should be pruned more and the pruning degree should be increased appropriately. Strictly control the total number of flower buds and the ratio of leaves to flowers, which is generally 1∶20. For young trees with few flower buds, it is necessary to lightly cut and leave more flower buds, and for branches and branches without flower buds, it is necessary to re-cut and update the fruiting branches.

(3) Look at the tree body: lightly cut the vigorous trees, remove the upright and stout branches, and leave the lateral branches and moderate branches to ease the tree vigor and promote the formation of flower buds; Weak trees should be pruned again, weak branches and drooping branches should be cut off, and the aging branches should be updated.

④ Look at the variety characteristics: Varieties with strong budding ability and strong branching, such as Fuji and Guoguang, are easy to cause canopy, poor illumination in the chamber, large pruning amount, and sparse branches should be cut when pruning.

⑤ Look at the cultivation management conditions: trees with good soil, fertilizer and water management conditions and strong trees should be lightly cut; On the contrary, for trees with thin slopes and poor management conditions, the pruning amount should be larger, and the pruning degree should be appropriately heavier, with less thinning and more pruning. After each pruning, a new layer of high-fat film should be put on the wound to make the wound heal quickly. The whole garden is sprayed with tree-protecting generals to protect the winter safely.
