What should I pay attention to when cutting apple trees in winter? Please instruct the apple trees to pay attention to the following points in winter pruning: ① look at the tree age: young trees and early fruit trees should be trimmed less, the degree of pruning should be light, pay attention to the cultivation of tree type and fruiting branch group; trees should be properly re-pruned in full fruit period, pay attention to rotation fruiting branch group; heavy pruning of senescent trees, renew fruiting branch group. ② look at the amount of flower buds: the amount of pruning of fruit trees with large amount of flower buds should be greater, and the degree of pruning should be increased appropriately. The total amount of flower buds and the ratio of flower buds to leaf buds are strictly controlled, and the ratio of flower buds to leaf buds is generally 1 ∶ 20. For young trees with few flower buds, gently cut and leave more flower buds, and re-cut and renew fruiting branches for branches and branches without flower buds. ③ look at the tree body: strong and prosperous trees should be pruned lightly, to erect strong and strong branches, leaving side standing branches and mediocre branches, in order to ease the tree potential, and then promote the formation of flower buds; weak trees should be heavily pruned, weak branches and drooping branches should be cut off, and the aging fruiting branches should be renewed. ④ look at the variety characteristics: varieties with strong sprouting and branching ability, such as Fuji and Guoguang, are easy to cause crown closure, poor inner chamber light, large pruning capacity and less interception of mediocre branches when pruning. ⑤ looks at the cultivation and management conditions: trees with good soil, fertilizer, and water management conditions and strong trees have a light degree of pruning; on the contrary, trees with thin hillsides and poor management conditions should have a larger amount of pruning, and the degree of pruning should be more serious, less thinning and more pruning, and the wounds should be smeared with healing film after each pruning to make the wounds heal quickly. Tree protection generals are sprayed throughout the garden to survive the winter safely. Click to get more apple tree planting techniques click to get more fruit planting techniques
