林木营养生长和生殖生长调控技术研究进展

Advances in Regulation Techniques for Vegetative and Reproductive Growth of Trees Species

林木营养生长和生殖生长相互促进、相互制约,并且在一定范围内的相对比例可以相互转换。在林木生产实践中常需根据不同的经营目标采用不同的技术或方法,调控二者之间的相对比例,从而实现最大的经济效益。文中综述了影响二者相互转换的主要因素及调控机制,系统总结了水肥管理、生长调节剂应用和其他调控措施的研究进展,并针对当前林木营养生长和生殖生长的调控研究现状提出了研究展望,以期为加快实现人工林的定向培育提供参考。

The vegetative growth and reproductive growth of trees promote and restrict each other,and their relative proportion can be converted in a certain range.In the practice of forest production,it is often necessary to apply different techniques or methods to regulate the relative proportion of vegetative growth and reproductive growth according to different objectives,so as to achieve the maximum economic benefits.This paper reviews the main factors and the corresponding regulatory mechanisms affecting the conversion between vegetative growth and reproductive growth of trees,summarizes the research progress in water and fertilizer management,plant growth regulators application and other regulating measurements,and finally prospects the future research based on the current study on the regulation of vegetative growth and reproductive growth of tree.The study will provide references for accelerating the oriented cultivation of forest plantations.
