Winter is the dormant period of apple trees. At this time, the activities of the trees are relatively weak, and the branches on the upper surface of the trees have relatively little storage and nutrition. It is very important to manage apples in the winter.
1, early removal of pests and fruit, and spray a new high-fat membrane, is conducive to isolate the bacteria, 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 the stored nutrients in winter fruit trees have been transported to the roots and stems. Cutting off the useless branches at this time can save a lot of nutrients, which is beneficial to the growth of tree growth in the coming 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.
