果树生产的现代化要以科学管理为基础;科学管理必须以掌握果树植物生长发育规律为基础。人们是从不同角度来研究、揭露这种规律的。有的从营养方面,有的从生态方面,有的从调节技术方面等等。从植物激素的角度研究植物生长发育规律是近十几年来植物生理学中发展较快的一个重要方面。 所谓植物激素是指植物体内有机的、微量的、非营养的化合物,可以由合成部位运到起作用的部位,在生长发育中起调节作用。迄今 The modernization of fruit tree production should be based on scientific management. Scientific management must be based on the rules of fruit tree growth and development. People study and expose this law from different angles. Some from nutrition, some from the ecological aspects, and some from the regulation of technology and so on. Studying the law of plant growth and development from the perspective of plant hormones is an important aspect of plant physiology that has developed rapidly in recent ten years. The so-called plant hormone refers to the plant organic, trace, non-nutritive compounds, can be transported from the synthesis site to the site of action, play a regulatory role in the growth and development. so far
