Excellent apple varieties have not been cultivated as large-scale economic cultivation in China for a long time, only a few decades, but the research and development of plastic pruning technology is faster than any fruit tree. This is because although apple planting has good benefits, it needs high pruning technology to ensure it. Production practice has proved that fruit trees without cultivation not only bloom and bear fruit late, but also tend to be unbalanced in growth and development. Therefore, the pruning technology is very important for the early fruiting, high yield, high quality and stable yield of apples, and fruit farmers also attach great importance to it. In recent twenty years, the plastic methods and pruning techniques suitable for dwarf close planting have been further discussed and tested. Although they are not perfect, great progress has been made in early fruiting and high yield. The transformation of the old tree structure is also widely carried out, and some technical experience has been obtained.

At present, all well-managed apple orchards can basically prune apple trees with different varieties, densities and ages, and the annual yield and benefits are considerable. However, in the newly developed production areas, there are also many apple orchards that are pruned extensively or even left uncultivated, with young trees flowering and bearing fruit late, big trees bearing little fruit, poor quality and low income. In severe cases, seeing branches is fruitless, occupying land and earning no income. Finally, I had to plane the tree.
