促进林木速生丰产,提高森林生产率,是当前营林工作的主要方向。而探讨提高林木产量的理论基础,则是现代林业科学的最主要任务之一。树木生理学的研究在这方面应起着重大的作用,因为它可加深对林木有机体中所发生的各种现象的本质的了解。林木生长是很多生理过程和生理状况相互作用的最终结果。林木的基本生理过程有光合和呼吸作用、水分蒸腾、营养代谢等。主要的生理状况有原生质的特征、叶绿素含量、细胞 Promote forest fast growing and improve forest productivity, is the main direction of the current forest work. However, it is one of the most important tasks in modern forestry science to explore the theoretical basis for improving forest yield. Research in tree physiology should play a major role in this regard as it deepens the understanding of the nature of the phenomena that occur in forest organisms. Forest growth is the end result of many physiological processes and physiological interactions. The basic physiological processes of forest photosynthesis and respiration, water transpiration, nutrition and metabolism. The main physiological conditions have the characteristics of protoplasm, chlorophyll content, cells
