大豆秸秆栽培香菇研究

利用大豆秸秆设置不同培养基替代木屑和麸皮栽培香菇,分析各培养基对香菇子实体产量、经济性状、氨基酸含量、经济成本的影响。结果表明:培养基中大豆秸秆含量15%左右代替木屑栽培香菇效果较好,同时替代麸皮时培养基中大豆秸秆含量可达35%;大豆秸秆可以完全替代麸皮栽培香菇,并能提高鲜菇商品性,丰富子实体氨基酸含量;生产10 000袋香菇可降低生产成本达4 250元。研究结果可为有效利用大豆秸秆高效栽培香菇提供参考。

Utilization of Soybean Strawsfor Cultivating Lentinula edodes

Differently formulated substrates consisting of soybean straws to replace sawdust or wheat bran were used to cultivate Lentinula edodes for evaluation.The resulting yield,economics,amino acid content,and production cost of the mushroom fruit bodies were analyzed.It was found that the medium containing 15％ of the soybean straws could be applicable for the cultivation.In fact,as high as 35％ of soybean straws in a medium could substitute wheat branto achieve a same fresh mushroom production and amino acid content in the fruiting bodies.By doing so,a saving of 4 250 yuan in producing 10 000 bags of L.edodes could be realized.The information suggested means to effectively utilize soybean straws for the mushroom cultivation.
