Abstract: To evaluate the feasibility of cultivation of Gastrodia elata Bl. with walnut wood as an alternative to traditional materials, the field cultivation of Gastrodia elata Bl. with walnut wood and traditional cultivation substrates was carried out in Hezhang in Guizhou Province. The results showed that the mycelium of Armillariella mellea in mixed substrate of walnut with traditional materials developed faster with thicker and stronger mycelium and higher coverage. There were differences in the effects of different materials on the yield of Gastrodia elata Bl. f. elat and Gastrodia elata Bl. f. glauca S. Chow. The two types of Gastrodia elata have different preferences for substrates. The yield of Gastrodia elata Bl. f. glauca was higher than Gastrodia elata Bl. f. elata by culture with mixed substrates of walnut with tradition materials. The use of walnut combined with traditional substrates can improve the yield of Gastrodia elata Bl and increase the bioconversion rate of the substrates under certain conditions. Results of this study showed that walnut materials could be used for the cultivation of Gastrodia elata as an alternative to traditional substrates.
