不同碳氮比培养基对泰山赤灵芝农艺性状的影响

Effect of Different C/N Ratio in Cultivation Medium on Agronomic Characters of Ganoderma lucidum

采用木屑、棉籽壳和麦麸为主要原料,配成不同碳氮比的培养基用以栽培泰山赤灵芝(Ganoderma lucidum),探索培养基中不同的碳氮比对其农艺性状的影响。结果表明,泰山赤灵芝菌丝在10种碳氮比栽培料处理上均能生长,且都能形成子实体,但存在差异。在碳氮比为30.23∶1~47.47∶1,菌丝生长最好,表现为菌丝生长速度快,健壮浓密;在碳氮比为30.23∶1~38.00∶1,子实体商品性状好,且产量和生物学效率最高。综上所述,泰山赤灵芝栽培较适宜培养基碳氮比为30.23∶1~38.00∶1。

In order to explore the effect of C：N ratio on the agronomic characters of Ganoderma lucidum, we used the sawdust, cottonseed hull and wheat bran as the main material with different C：N ratio to cuhivate the G. lucidum. The results showed that the G. lucidurn could grow and form fruitbody in 10 treatments. When the C：N ratio were from 30.23：1 to 47.47：1, the myeelial growed rapidly and strong, while the C：N ratio were from 30.23：1 to 38.00：1, the yield and biological efficiency were the highest with the good commodity character. In summary, the optimum C：N ratio of G. lucidum was from 30.23：1~38.00：1.
