环境因子影响兰花生长机理的研究进展

环境因素调控对兰花栽培技术的改进和创新有着非常重要的意义，是兰花资源保护与开发研究领域的一个重要组成部分．兰花的生长与生理受环境温度、相对湿度、光照、栽培基质、施肥等因素的影响．本文综述了国内外环境因素与兰花生长机理之间的关系．今后的研究应集中在以下方面：（1）探讨和比较研究不同环境因素多梯度兰花的生长与生理，逐步扩大生长与生理研究的范围；（2）研究多种兰花生长机理的共性，进一步加强特性的研究；（3）进行环境因素与兰花生长机理的多学科合作研究，将为兰花资源保护与开发做出新的贡献．

Advances in the Mechanism of Environment Factors Influencing Growth of Orchid Plants

The reasonable control of environment factors is considerably important for modification and innovation of cnltivation technologies for orchid plants. Information about the mechanism of environment factors influencing growth of orchid plants is a major contributor to field of research on protection and exploration of orchid resource. Critical factors influencing the growth and physiology of orchid include environment temperature, relative moisture, light condition, cultivation mcdinm , fertilization measurements. Despite intensive research in recent years, many uncertainties remain in this important field of research. In the future, topics of particular importance include： 1） Comparison of the growth and physiology of orchid in multi-gradients of different environment factors and enlarge research range of the growth and physiology： 2） Emphases on research characteristic of orchid plants; 3） Inter-disciplinary research on the mechanism mentioned above will facilitate the process of protection and exploration of orchid resource greatly.
