Abstract:
The effects of different cultural environment were studied on the growth and chemical compositions of
Dendrobium nobile on the basis of specific Climatic conditions of Chongqing.The results showed that
D.nobile cultured in natural forest were better,which was nestled up to trunk by the rope of rice straw and nylon cable ties.There were significant differences in active component and water content under different culturing conditions of greenhouse,natural forests and plantation.The active component content of
D.nobile cultured in forests was more than that in green house.Especially the content of total polysaccharides was higher than that in
D.nobile cultured in Chishui of Guizhou Province.
