摘　　要：以秀珍菇为试材,研究了31种不同碳氮比栽培料对秀珍菇菌丝和子实体产量及生物学效率的影响,以期筛选出最适宜秀珍菇生长发育的最佳碳氮比的栽培料。结果表明:秀珍菇菌丝在31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67∶1～69∶1的栽培料处理上菌丝生长最好,表现为菌丝生长速度快,且洁白浓密。在所设置的处理间,随碳氮比的增加,生物学效率呈增加趋势,当碳氮比达到69∶1时生物学效率达最高峰,此后随碳氮比的增加生物学效率逐渐下降。综合考虑营养生长和生物学效率二方面的因素,最适宜秀珍菇生长发育的碳氮比为68∶1～69∶1。To screen out the most suitable C/N cultivation material of Pleurotus geesteranus growth, the effect of different C/N cultivation ：material on mycelial growth, fruitbody yield and biological efficiency of Pleurotus geesteranus were studied. The results showed that the mycelial and fruitbody of Pleurotus geesteranus could grow in every treatment, but it had difference. Mycelial of Pleurotus geesteranus grow rapidly,vigorous, pure white and bushy when the C/N were from 67 ： 1 to 69 ： 1,the biological efficiency was increasing step by step when C/N was increasing from 52 ： 1 to 69 ： 1,the biological efficiency was the highest when the C/N was 69 ： 1. Then the biological efficiency was depressing gradually over 69 ： 1. Comprehensive consideration of the vegetative growth and biological efficiency two factors, the optimum C/N of Pleurotus geesteranus was from 68 ： 1 to 69 ： 1.
