(1) Because the tree is trimmed, follow the branches.
It means that there must be tree-shaped requirements when modeling, and it must be flexibly mastered according to different conditions of different plants, and it is necessary to follow the trend with the branches and guide the formation; Be tangible and immortal, intangible and not chaotic. For the requirements of a tree, we should focus on the tree height, crown size, total number of trunk branches, distribution and affiliation, branch ratio and so on. The pruning of different plants does not need to be consistent, so as to avoid rigid copying and mechanical stereotypes. Excessive pruning will inevitably inhibit growth and delay results.
(2) Overall consideration, combining long and short.
It means that we should consider both the results and the long-term success. From a long-term perspective, we should make long-term plans and short-term arrangements. Young trees should not only be well shaped, but also be conducive to early fruiting, so that growth and fruiting are right. If we only emphasize the tree shape and ignore the early results, it is not conducive to the improvement of economic benefits and the relaxation of tree potential. If one-sided emphasis is placed on early high yield and many fruits, it will lead to poor tree structure and weak skeleton, which is not conducive to the improvement of future yield. Both growth and fruiting should be taken into account in the full fruit stage, and on the basis of high yield, stable yield and high quality, nutritional growth should be strengthened to prolong the full fruit stage.
Give priority to with light, light and light combination.
It means to reduce the amount of pruning as much as possible and reduce the inhibitory effect of pruning on the whole fruit tree. Young trees, in particular, should be lightly cut and more branches should be left, which is conducive to tree growth, crown expansion and tree relaxation, and achieve the purpose of early fruiting and high yield. Too light pruning will inevitably reduce the number of branches and long branches, which is not conducive to plastic surgery; In order to construct the skeleton, it is necessary to trim the backbone branches at all levels according to the requirements of plastic surgery to help them grow and control the results. Only in this way can we cultivate a solid skeleton and cultivate various branches. Auxiliary branches should be cut lightly and put long to promote them to form more flower buds and bear fruit early. It should be pointed out that light shearing must be carried out on the basis of certain growth potential. 1 ~ 2-year-old young trees can be cut lightly and put long only on the premise of promoting them to produce enough robust and vigorous branches. In this way, a large number of branches can be generated and the purpose of increasing the number of branches can be achieved. When the tree is too weak and the number of long branches is small, light cutting and long putting will not only affect the cultivation of backbone branches, but also affect the results. Therefore, cutting short 1 ~ 2 years after planting, promoting branching and creating conditions for light cutting and slow release are the key measures for early fruiting.
