摘要
以杏鲍菇为试材,采用菌丝培养和麦角甾醇含量测定2种方法,对金针菇菌糠栽培杏鲍菇时氮源的改良作用进行评价。结果表明:金针菇菌糠的有机碳和总氮含量分别为64.05%和1.72%;玉米粉对杏鲍菇菌丝生长速度的促进作用最明显,其栽培的杏鲍菇菌丝生长速度为4.3mm/d,其次是麦麸,为3.6mm/d,而麦麸米糠混合组的杏鲍菇菌丝长势最佳;杏鲍菇菌丝含麦角甾醇最高的是麦麸米糠混合组(麦角甾醇含量为0.20mg/g),其次分别是米糠组和玉米粉组,麦麸组的含量最低;可以判断麦麸和米糠混合使用是改良金针菇菌糠的最佳氮源。
Taking Pleurotus eryngii as test material,the modified effect of nitrogen source on the cultivation of P. eryngii by mushroom bran of Flarnmulina velutipes was evaluated by mycehum culture and ergosterol content determination. The results showed that organic carbon and total nitrogen content of the mushroom bran were 64. 05% and 1.72%. Corn powder had the most obvious promote effect on the growth rate of Pleurotus eryngii mycelium for 4. 3 mm/d,followed by wheat bran,3. 6 mm/d. Pleurotus eryngii mycelium had the highest wheat bran rice bran mixed group （0. 20 mg/g）, followed by rice bran and corn powder group, wheat bran group was the lowest. In conclusion, wheat bran and rice bran nixed was the best nitrogen source for improvement of Flammulina velutipes bran.
