修剪必须围绕一定的经济目标进行,漫无目标的修剪,不会产生经济效益,甚至会减产。修剪在果树生产环节中占重要地位,它不但是调节性的技术,而且具有创造高产的直接作用。为达到早果、高产、稳产、优质和低成本的经济目标,必须制订全面的、综合性的和规范性的技术指标;修剪必须和其他管理环节密切配合才能达到既定的经济目标。用修剪方法创造“开放型”的“三稀三密”树冠,要比“封闭型”的“三密”树冠具有充分利用空间、充分利用光能和充分利用CO_2的能力,因此是高产树形。掌握修剪量,控制叶果比,是早果、高产、稳产、优质和低成本的关键。应重视根系修剪的作用,并深入进行研究,以期通过根系管理提高生产水平。
Pruning must be carried out around certain economic goals. Targeted pruning will not bring economic benefits and will even reduce production. Pruning occupies an important position in the production of fruit trees, it is not only a regulatory technology, but also has the direct effect of creating high yield. In order to achieve the economic goals of early fruiting, high yield, stable yield, high quality and low cost, comprehensive, comprehensive and normative technical indicators must be formulated; pruning must be coordinated with other management processes in order to achieve the stated economic goals. The pruning method of creating “open” “three-dilute three-density” canopies is more efficient than the “closed” three-density canopies and makes full use of the light energy and the ability to make full use of CO_2. . Master the amount of pruning, control of fruit ratio, is the early fruit, high yield, stable yield, high quality and low cost key. Should pay attention to the role of root pruning, and in-depth research, with a view to improving production through root management.
