After entering the winter, the temperature will drop to a very low level, and it is easy to cause frost damage to the fruit trees.
1. For the main branches and the main frozen fruit trees, the branches that are germinated by the buds of the branches and the bases should be short-cut at the full buds to promote branching. Then, the backbone branches of each level are separately cultured, and the number of branches should be shortened within 2 to 3 years to control the results, so as to facilitate the rapid increase of the number of branches.
2. Some frozen fruit trees have no pumping phenomenon, but the tree body is weak, the new shoots are short, the flowers are more serious, and the diseases are easy to be infected. For those fruit trees with lighter frost damage, the main and side branches should be trimmed. The permanent auxiliary branches are all short at the full buds and promote the development of the tree. In addition, it is necessary to cut off some flower buds to make it less fruitful, in order to restore the tree potential.
3, for frozen apples lacking branches, should use the long branches to make up for the space, lightly cut in 1 to 2 years, retain the amount of shoots, and promote their germination more branches. Within 3 to 4 years, each branch should be cut, and after the result, it should be appropriately retracted according to the canopy space, and cultivated into a permanent auxiliary branch or result branch group. This will restore the canopy after 4 to 5 years of cultivation.
