在目前果树矮密栽植中,用环剥等外伤手术控制树冠大小已作为一项普遍的技术措施在生产中应用。特别是在乔化密植栽培技术下,控制树体过旺的营养生长,以促进早结果,以果压冠,达到密植的目的,环剥的作用更为显著。环剥主要是通过在一定时期内调节树体内营养分配,增加环剥口以上部位光合作用的积累:提高地上部 C/N(碳、氮)比值,来实现其调节营养生长和生殖生长之间的关系,营养生长是生殖生长的基础,双方既互相矛盾,又相互依赖。因此,在果树上应用环剥技术时,一定
In the current planting of low-density fruit trees, the use of girdling and other traumatic surgery to control the crown size has been used as a common technical measures in the production. Especially in the Qiaochu close planting cultivation techniques, the control of excessive vegetative growth of the tree to promote early results, if the crown pressure, to close planting purposes, the role of girdling even more pronounced. Girdling mainly through the regulation of the distribution of nutrients in the tree within a certain period of time, increasing the accumulation of photosynthesis in the above parts of the epidermis: raising the ratio of C / N (carbon and nitrogen) aboveground to realize its regulation of vegetative and reproductive growth The relationship between vegetative growth is the basis for reproductive growth, both contradictory and interdependent. Therefore, the application of girdling technology in the fruit tree, must
