摘　　要：以香菇‘申香16'为供试菌株,以硬杂木为主要碳源,研究了以麸皮及玉米粉为主要氮源材料对香菇菌丝生长、发菌、转色、出菇以及产量等指标的影响,试验表明香菇栽培中适量添加玉米粉有利于提高香菇菌丝生长速度,缩短发菌周期,且随着玉米粉含量的增加,菌丝生长速度呈先增加后减少的趋势,当麸皮含量为14%玉米粉含量为6%时,菌丝生长速度最快;香菇栽培中适量添加玉米粉可以起到增产的效果,但随着玉米粉在复合氮源中比例的增加香菇产量呈递减的趋势,当麸皮含量为18%麸皮玉米粉含量为2%时香菇产量最高。Lentinus edodes ＇Shenxiang 16＇ and hard wood were used as test strain and carbon source respectively to investigate the effects of nitrogen source materials such as bran,corn flour on mycelium growth,spawn running,coloring,fruiting and yield.The results showed that adding corn flour could improve mushroom mycelium growth rate,shorten the hair cycle.With the increase of content of corn flour,mycelium growth rate firstly increased and then decreased.The mycelium growth rate reach peak when the cultivated with 14%bran content and 6%corn flour.Adding corn flour could improve the yield of Lentinus edodes,but the yield showed a descending trend with the increase of content of corn flour.The yield of Lentinus edodes reach peak when the cultivated with 18%bran content and 2%corn flour.
