Abstract  In order to reduce consumption of sawdust , make full use of the resourceful corn stalks in Lentinula edodes ( Berk) Pegler cultivation , five indexes including the contents of carbon ( C ) and nitrogen ( N ) , C/N ratio in cultural materials , the contents of essential amino acid ( EAA ) and nutritional index ( NI) in L.edodes were analyzed and optimized by formula uniform design with corn stalk powder as main cultivation substrate , sawdust and wheat bran as supplemental cultivation substrates.The results indicated that the contents of corn stalk powder and sawdust was significant negative and positive correlation with the content of EAA and NI , respectively . Moreover , the contents of C and N , C/N ratio were regressive correlation with EAA , and prominent positive correlation with NI.Therefore , there was not a pronounced change in the contents of EAA and NI when the content of corn stalk powder was lower than ７４.５０％ and the content of sawdust not less than １１.６４％ , indicating that it was feasible to cultivate L . edodes with corn stalk instead of sawdust with important economic and social values .

玉米秆代料培养料栽培香菇的配方均匀设计优化及营养分析

为了节省香菇生产对木屑资源的消耗,充分利用资源丰富的玉米秸秆,以玉米秸秆粉为主料,栎木屑和麦麸为辅料,采用有限制的配方均匀设计对其组合进行优化,并测定培养料中C 、N 含量及C/N 比,香菇必需氨基酸(EAA)含量和营养指数(NI)等５个指标.结果表明:玉米秸秆粉质量分数与香菇的EAA 含量、NI 存在显著负相关关系,栎木屑质量分数与香菇的EAA 含量、NI 存在显著正相关关系;培养料中的C 、N 含量和C/N 与EAA 存在显著的回归关系,与NI 间存在显著相关关系和回归方程,当玉米秸秆粉质量分数低于０.７４５０ ,栎木屑质量分数不低于０.１１６４时,不会对EAA 含量和NI 造成显著影响.说明玉米秸秆代料培养是可行的,有重要的经济价值和社会价值.
