以鼓槌石斛为试材,利用人工调节遮阳网的层数和高度形成不同的光照环境种植鼓槌石斛,试验6个月后,测定鼓槌石斛茎粗、株高等生长指标和氨基酸、多糖、毛兰素、总酚等有效成分含量。结果表明:在透光率50%的光照条件下,鼓槌石斛的茎增粗最明显,株高增长率最快;不同光照条件的鼓槌石斛中所含的氨基酸含量、多糖、毛兰素、总酚含量有显著差异。其中,在7月,透光率仅为10%的条件下,鼓槌石斛中总酚、毛兰素含量最高,分别为0.945%、0.164 4%;在11月,透光率50%的遮荫条件下,多糖含量成分最高为6.388%。遮荫对鼓槌石斛的生长特性、多糖、总酚、毛兰素有显著影响。 With Drumstick Dendrobium as test material, Dendrobium candidum was formed by artificial adjustment of the number and height of shading net. After six months of experiment, the growth index of stems, plant height and the contents of amino acids, polysaccharides, Erianin, total phenols and other active ingredients. The results showed that under the illumination of 50%, the stem thickening was the most obvious and the growth rate of plant height was the fastest. The contents of amino acids, polysaccharides, ementin There was significant difference in total phenolic content. Among them, in July, under the condition of light transmittance of only 10%, the content of total phenols and erianin in Drum Dendrobium was the highest, which were 0.945% and 0.164 4% respectively; in November, the light transmittance of 50% Under the shade, the content of polysaccharide is up to 6.388%. Shade on Drum Dendrobium growth characteristics, polysaccharides, total phenols, Erian hormone have a significant impact.
