摘　　要：针对近年姬菇栽培主要原料之一的稻草粉价格大幅度上涨,栽培成本不断增加,导致栽培经济效益不断下滑的现实问题,在主产区现有栽培料配方(CK)基础上,设计了6个姬菇栽培料配方,以农村丰富的玉米杆、油菜杆、小麦杆、猕猴桃枝、桑枝屑、高粱壳等资源部分替代稻草,进行姬菇栽培试验。结果表明,配方5(添加高粱壳)的菌丝生长势强、生长速度最快(0.92 cm/d),鲜菇产量最高(0.77 kg/袋),高出CK(0.71 kg/袋)的8.45%,且差异显著;S级菇比例最高(69.68%),即优质菇的比例最高,高出CK(63.88%)的9.08%;其鲜菇利润(1.21元/袋)和盐渍菇利润(1.24元/袋)都最高,分别高出CK的9.1%和21.57%,这一配方部分替代料稻草,栽培经济效益高,可在生产上示范应用。认为姬菇培养料的最适宜C/N为(28～29)∶1。Based on existing cultivation formulations in the main producing areas of Pleurotus cornucopiae,six cultivation formulations containing corn stalk,rape rod,wheat straw,kiwi sticks,mulberry cuttings,sorghum shell partial substitution of straw were used to cultivate P.cornucopiae.The results showed that,when P.cornucopiae was cultivated in No.5 formulation（added sorghum shell）,the mycelium growth potential was the strongest and fastest（0.92 cm/d）,the fresh mushrooms yield（0.77 kg/bag） and proportion of S grade mushroom（high quality mushroom） was highest,fresh mushroom profits（1.21 yuan/bag） and salted mushroom profits（1.24 yuan/bag） were the highest.The conclusions were drawn that No.5 formulation should be used in production and the most suitable for C/N for P.cornucopiae cultivation material was（28-29）∶ 1.
