邵武将石省级自然保护区铁皮石斛生物学特性及生态环境的初步观察

Preliminary study on the biological characteristics and ecological environment of Dendrobium officinale in Shaowu Jiangshi Provincial Nature Reserve

邵武将石省级自然保护区气候温暖湿润,其密集、形态多异的丹霞地貌是兰科石斛属植物最适合生长的生态环境区。通过民间访查、实地调查及人工栽培的方法进行观察研究,发现该区铁皮石斛生长在通风较好的西北、东北向的阴坡悬崖石壁上,生长环境要求湿度高,光照时数影响不大,耐干旱,对土壤有机质要求不高,但要求偏酸性土壤,通透性要好,怕积水。常与苔藓、地衣、石韦等形成小群落。针对该资源濒临灭绝现状,提出保护利用的对策。

The climate is mild and wet in Shaowu Jiangshi Provincial Nature Reserve. The dense and multi-configuration Danxia landforms give the Orchid plant Dendrobium officinale a suitable living environment. Based on the civil investigation, field investigation and human cultivation, D. officinale was found living in well ventilation cliffs on the northwestern and northeastern shading slopes in this area. It needed high humidity, but no strict for illumination time. It was drought-tolerant, no strict for soil or- ganic substance but acidity, good permeability but no plash. It always created a small community with moss, lichen and pyrro6ia leaf etc. Aiming at its endangered resources, its conversation and utility policies are brought forward in this paper.
