Abstract:: Taking different bark substrate as test materials,taking Dendrobium officinale as test object，in order to investigate a suitable system for stereo planting of Dendrobium officinale，different bark substrate and different positions of the shelf of the elevate-cultivated strawberry were evaluated.The results showed that thin bark could improve the survival rate at the initial growth stage of D.officinale. However，thin bark could lead to root rot in the later period.Thick bark significantly improved the survival rate of D.officinale in the later period and showed an increment of growth.Effect of different light intensity with different position of the shelves on the growth of D.officinale mainly reflected in plant height and stem diameter.The highest plant of D.officinale was observed under the shelf of strawberry and the plant which had a maximum stem diameter was on the shelf.Comprehensive consideration of the yield of D.officinale and the interaction between the elevated substrate culture strawberry and D.officinale，which the space under the strawberry shelf and thick bark were advised for stereo planting model of D.officinale.
