利用天麻废弃菌材栽培3种食用菌的试验

为提高林木资源的利用率，实现天麻废弃菌材在食用菌栽培生产中的循环利用，以天麻废弃菌材为主要基质开展平菇、黑木耳、香菇3种食用菌的袋料栽培研究，测定了不同配方基质对3种食用菌的菌丝体生长速率和子实体生物转化率的影响，结果表明：天麻废弃菌材可作为食用菌的栽培基质开展袋料栽培，菌材基质中添加部分玉米芯材料时，3种食用菌的生物转化率均显著提高；基质配方B（60%菌材+30%玉米芯）栽培效果最好，平菇、黑木耳、香菇的生物转化率分别达到了59.45%、50.32%、52.49%。

Study on the 3 kinds of Edible Fungi Culture with the Wood Residues of Gastrodia elata

In order to improve the utilization rate of forest resources, and realize the recycling of the wood residues of Gastrodia elata in the cultivation and production of edible fungi, the cultivation of bagged materials of 3 edible fungi of Pleurotus ostreatus, Auricularia auricula and Lentinus edodes mushroom was carried out with the wood residues of G. elata cultivation as the main substrate. The effects of different formulations on the mycelium growth rate and fruiting body bioconversion rate of the 3 edible fungi were determined. The results showed that the wood residues of G. elata can be used as bagged cultivation substrate for edible fungi. When some corncob materials were used, the bioconversion rates of the 3 edible fungi were significantly improved. The matrix formula B (60% fungus + 30% corncob) had the best cultivation effect, and the bioconversion rates of the 3 edible fungi increased to 59.45% (Pleurotus ostreatus), 50.32% (Auricularia auricula ), and 52.49%(Pleurotus ostreatus), respectively.
