The invention discloses a dendrobe planting matrix. The planting matrix is prepared from, by weight, 25-32 parts of pine bark, 12-14 parts of pinecones, 5-8 parts of wood shavings, 11-13 parts of peanut shells, 0.03-0.05 part of fermented active matter, 15-19 parts of peat, 11-13 parts of charcoal, 9-11 parts of perlite, 8-10 parts of ceramsite and 1-2 parts of trichoderma agent. The dendrobe planting matrix has the advantages that the planting matrix has the better water permeability, gas permeability, water retaining capacity, soil workability and supervenience, the trichoderma biomass can be prevented and treated, pathogenic microorganisms in dendrobe in the micro-ecology in a planting region are restrained, triggering factors of dendrobe microorganism diseases are reduced, the dendrobe planting survival rate is effectively increased, and the dendrobe finished medicinal material quality is improved; the preparation method of the prepared matrix is simple in technology, easy to control, stable in product stability, high in adaptability, capable of saving energy, environmentally friendly and convenient to implement.
