If it is a young apple tree, the main purpose of pruning is to determine the tree type that promotes growth. If it is a fruit-bearing apple tree, the purpose is to protect flowers and promote fruit formation. As for the aging apple tree, the purpose is to keep the tree stable. Thinning branches: The most common method of pruning fruit trees in winter is pruning branches that are not conducive to the growth of fruit trees to balance the tree potential. The main purpose is to prune too dense branches, solve the problem of poor canopy of fruit trees, and remove young trees with dead branches in the third year in time. After pruning in winter, pull the branches to April-May of the following year. Some fruit farmers will pull branches directly when pruning in winter.

After the branches are slowly released, buds should be carved in spring to promote the growth of medium and short branches, especially red and fertile soil varieties. If you don't pull the branches and carve the buds, it is easy to have "bare legs" under the branches. We should have a sense of catching up, innovate boldly and improve the management level of fruit trees. Make good use of your own advantages, learn from each other's strengths, manage the fruit trees well, and improve the quality and efficiency of the apple industry.

Long-term factors should be considered when pruning. Young trees should be pruned well, and fruit trees in the fruiting period should not be under too much pressure. Pruning should be based on a good tree structure and a solid skeleton. The perennial branches planted on the back of the main branches should be treated in time to prevent trees from growing on the trees. For Marshal varieties with short fruit branches, they should be released for as long as possible before vegetative growth is transformed into reproductive growth, and they should be uniaxially stretched without fruit and retraction.

Winter scissors are strips for strips, and pruning is more sensitive. Pruning a little more will induce the branches to grow more vigorously, resulting in more branches, high nutrient consumption, closed crown, poor scenic conditions and poor photosynthetic efficiency. Short cut: also known as short cut, that is, cutting off part of annual branches. Short cutting can stimulate the growth of branches locally, and the closer to the incision, the more obvious the reaction is. Generally speaking, short cuttings promote branching and stimulate the growth of new shoots.
