Apple tree pruning
1. Look at the age of this tree. The pruning amount and degree of young trees and early-bearing trees should be small, and attention should be paid to cultivating tree shapes 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 amount of 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 this tree. The trees with vigorous growth should be lightly cut, and the upright and stout branches should be removed, leaving lateral branches and moderate branches to ease the tree growth 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 thick branches, such as Fuji and Guoguang, are easy to cause crown closure, poor indoor light and large pruning amount, so sparse branches should be intercepted when pruning.

5. Look at the breeding management conditions. Trees with good soil, fertilizer and water management conditions and strong trees should be lightly cut; On the contrary, trees with thin slopes and poor management conditions should be pruned more, and the pruning degree should be heavier, less sparse and more pruned.
