Five look 1. Look at the age of the tree. The amount of pruning of saplings and early-fruiting trees should be small, and the degree of pruning should be light. Pay attention to cultivate tree type and fruiting branch group; trees in full fruit period should be properly pruned, pay attention to rotating fruiting branch group; senescence tree should be pruned again, and fruiting branch group should be updated . 2. Look at the amount of flower buds. Fruit trees with a large amount of flower buds should be pruned more, and the degree of pruning should be increased appropriately. Strictly control the total amount of flower buds and the ratio of flower to leaf buds. The ratio of flower to leaf buds is generally 1:20. For young trees with few flower buds, lightly cut and keep more flower buds, and for branches and branch groups without flower buds, cut and renew the fruiting branch group. 3. Look at the tree. Light pruning is necessary for strong and vigorous trees, to erect strong and vigorous branches, leaving side branches and moderate branches to ease the tree vigor and promote the formation of flower buds; weak trees should be pruned heavily, cut off weak branches and drooping branches to renew the senescence and fruiting branches . 4. Look at the variety characteristics. Varieties with strong budding ability and branching ability, such as Fuji, Guoguang and other varieties, are easy to cause canopy canopy, poor inner chamber light, and the amount of pruning should be large. When pruning, you should sparse and intercept moderate branches. 5. Look at the cultivation and management conditions. Trees with good soil, fertilizer, and water management conditions and strong tree bodies should be pruned lightly; on the contrary, trees with thin hillsides and poor management conditions should be pruned more heavily, and pruned more appropriately, with less sparseness and more pruning. Four attention 1. Don't wear hard-soled shoes when cutting in winter, especially leather shoes, big-toed shoes and spiked shoes. It is better to wear rubber shoes and cloth shoes. 2. When opening the angle with artificial branches, pulling branches, etc., do not use too much force or too much force. First, soften the branches to avoid stretching and splitting the branches. 3. Sterilize the cutting edge while cutting. Commonly used drugs include 10 times Guo Kangbao, 30 times liquid 9281 and 3 Baume Duo Liquor. 4. Cut off pests and diseases.
