整形修剪是果树生产上的一项重要措施。通过整形修剪,可以调节树体与外界环境条件的关系,使果树能最大限度的利用光、空气和根系吸收的营养,调节生长与结果的关系,达到合理的树体结构,保证丰产稳产。在果树生产的进程中,整形修剪由简单到复杂。为了达到果树的早期丰产并适应机械化的需要,目前整形修剪又趋向简化。在这变化很大的情况下,如何灵活运用国内外的先进经验,特别是对生产上现有的稀植大树来说,要克服盲目性,首先必须理解果树修剪的生理基础,掌握果树修剪的原则,才能园地制宜以取得事半功倍的良好效果。
Plastic trimming is an important measure in the production of fruit trees. By shaping and pruning, the relationship between the tree and the environmental conditions can be adjusted so that the fruit tree can make full use of the nutrients absorbed by light, air and roots and regulate the relationship between the growth and the result to achieve a reasonable tree structure and ensure high and stable yield. In the process of fruit tree production, plastic trim from simple to complex. In order to achieve the early fruit tree yield and meet the needs of mechanization, the current plastic trim and tend to be simplified. In this great change circumstances, how to make the best use of advanced experience at home and abroad, especially for the production of existing thin tree planting, to overcome the blindness, we must first understand the physiological basis of fruit tree pruning, Principle, in order to achieve a better performance with less effort.
