The winter apple tree is dormant. When the tree activity is relatively weak, the organic nutrition is relatively collapsed, and the shoots are relatively less stored in the shoots. It is very important to manage the apple in winter. 1. Early removal of pests and fruits, and spraying Application of new high-fat membranes is conducive to the isolation of germs and improve the tree's nutritional storage. 2. In the cold regions of the north, it is beneficial to apply the trees and generals before the winter to improve their cold-resistance ability. 3, dry land or lack of fruit orchards to master the cold night, the whole garden irrigation once and spray a new high-fat membrane, inhibition of surface water evaporation, tree water transpiration. 4. Most of winter fruit storage nutrients have been transported to the roots and stems. Cutting off the useless branches can save a lot of nutrients, which is conducive to the growth of tree growth in the following year. 5, timely cutting scraping sawing wound, smearing anti-corrosion film to prevent chapped water loss, reduce nutrient consumption, promote wound healing has a very significant effect.
