摘　　要：研究不同菌材树种、菌材用量对甘孜州野生乌天麻(Gastrodia elata Bl.f.glauca S.Chow)无性繁殖的影响。结果表明,菌材树种对甘孜州野生乌天麻无性繁殖的产量和箭麻折干率均有极显著影响,刺叶栎类材质紧密树种所培养的天麻的产量和折干率极显著高于白桦类材质疏松树种;菌材用量对甘孜州野生乌天麻无性繁殖产量有极显著影响,但对箭麻折干率无影响。The effects of the tree species and the dosage of Armillariella mellea rhizomoph wood on asexual reproduction of wild Gastrodia elata Bl.f.glauca S.Chow were studied in Ganzi prefecture. The results showed that the tree species had a very significant effects on asexual reproduction yield of wild G. elata Bl.f.glauca S.Chow. The dry discount rate, the yield and the rate of its mature tuber caused by close grained wood such as Quercus spinosa David ex Fr. was very significantly higher than those caused by coarse grained wood such as Betula platyphylla Suk.. The dosage had a very significant effects on the yield of wild G. elata Bl.f.glauca S.Chow with no influence on the dry discount rate.
