摘要(Abstract):

以铁皮石斛设施栽培投入大、药材功效不如野生等问题为导向,通过水分调控、崖壁坡度选择,研究悬崖附生铁皮石斛生长情况、农艺性状、产量、多糖及醇溶性浸出物含量。结果表明,将铁皮石斛附生于85~90°悬崖表面,在生长季节喷水1~2 h·d-1的条件下,即使在裸露的环境中,不用基质,不施肥料也能够较好的生长,获得较高的产量,其形态与悬崖上野生铁皮石斛无异;多糖与醇溶性浸出物含量显著高于设施基质栽培,并与萌蘖生理年龄密切相关,逆境有利于铁皮石斛多糖与醇溶性浸出物等功效成分的积累。
To solve the issues of costly planting of facility cultivation method and inferior efficacy than wild herbs of Dendrobium officinale,the cliff epiphytic cultivation method was studied. To research the growth,agronomic traits,yield,polysaccharide and alcohol-soluble extract contents were measured on the D. officinale from different water regulation and cliff slope gradients treatments. The results showed that D. officinale epiphytic at 85°-90° cliff and sprayed water 1-2 h·d- 1at the growing season can get better growth and obtain high yield,and the morphology has no different from wild cliff D. officinale,even in the environments without shade. The contents of polysaccharide and alcohol-soluble extract are closely related to the physiological ages,but significantly higher than the facility cultivation. It is possible that environmental stresses benefit the accumulation of polysaccharides,alcohol-soluble extract and other efficient ingredients.
