How to prune apple trees in the New year

How to prune apple trees in the New year? Please give guidance on the pruning principles of Chinese New year trees. On the premise of ensuring the yield of the same year, properly control the retention of flowers and fruits, reduce consumption, increase accumulation, and promote flower bud formation. The specific methods are as follows: 1. In order to reduce flower buds and improve ventilation and light transmission, thinning or retraction of improperly positioned auxiliary branches and large backbone branches; thinning of overdense fruiting branches or fruiting branches; external extension branches should be cut at full buds, and the annual long branches below them should be properly thinned. The annual branches of the inner chamber are generally cut lightly or not except for long short cuts, so as to form a certain number of flower buds for the young. 2. Reduce flower buds and increase reserve branches. Heavy pruning of fruit branches in winter, renewal group, cutting short medium and long fruit branches, increasing the proportion of leaf buds, "changing flowers for flowers", in order to form a sufficient number of flower buds for the next year. When there are too many flower buds, it is necessary to rejuvenate a group of aging short fruit branches and branches. After pruning, the ratio of flower bud to leaf bud is about 1 ∶ 3. 3. There are many flower buds in big trees, which are difficult to distinguish in winter, so they can be re-cut when the flower buds are enlarged in spring. Remove redundant flower buds so that the Lunar New year will not be too old. 4. for the big year trees with strong growth potential, in the case of leaving too many fruits, they can be cut once at the base of the central stem or part of the big branches from late May to early June to promote the formation of flower buds. 5. For the varieties with strong annual developing branches and easy flowering, the long branches can form flower buds in the same year, and they should be cut more and less, so as to lay the foundation for not small years in the coming year; for varieties that are not easy to form flower buds, long branches are not easy to form flower buds in that year, and they generally have to blossom for 2 years in a row, and they can blossom and bear fruit only in the third year, and can be cut short in the big year, and then be dealt with as appropriate in the coming year. If a strong branch has been in place for a year, it should continue to grow and promote it to form flower buds, waiting for the small year to bear fruit.
