栽培天麻种群的退化及防控对策

The Degradation on Cultivated Gastrodia Populations and Prevention Measures

目的:本文提出栽培天麻种群退化的观点及防控退化的对策。方法:比较和论述自然天麻种群与栽培天麻种群在生物学特性、质量、产量等方面已表现的区别和差异。结果:栽培天麻种群的某些生物学特性和有些重要的质量性状正在发生改变和退化。结论:森林生态的破坏与减少和自然天麻种群的减少是导致栽培天麻种群退化的直接原因;而人工进行天麻授粉,人为的改变天麻种群的自然生长环境是引起栽培天麻种群退化的间接原因。

Objective ： To propose views and concepts on the degradation of cultivated Gastrodia populations. Methods ： The differences between natural and cultivated Gastrodia populations were compared and discussed in terms of their biological features, qualities and yields. Resuts： There were changes and degradation in biological features and some important properties of yield in cultivated Gast- rodia. Conclusion： The direct reason of cultivated Gastrodia degradation is the ecological disturbaee of forests and the decreasing a- mount of natural Gastrodia populations ; The indirect reason is manual pollination and other changes of the natural growing environment.
