摘要 平菇出菇后期采用不同覆土施肥处理,研究其对平菇产量和品质的影响。结果表明,3个覆土施肥处理均可显著提高平菇的产量,其中1%的复合肥处理的产量最高,为0.428 kg/袋;覆土施肥处理后平菇折干率显著高于CK的;平菇覆土施肥后提高了平菇的品质,其中1%氮肥处理最有效,各覆土施肥处理的可溶性蛋白和还原糖含量显著高于CK,表明平菇出菇后期不同覆土施肥处理均可提高平菇的产量和品质。

Abstract In order to study the effects of different casing soil fertilizer treatments on the yield and quality of Pleurotus ostreatus, some different treatments were selected. The result showed that the yield all increased significantly under three casing soil fertilization treatments, and 1% compound fertilizer treatment showed the highest yield, which was 0.428 kg per bag. The drying rate of P. ostreatus was much higher than the CK. The Pleurotus ostreatus quality of three treatments all increased, and 1% N treatment was the most effective. The contents of soluble protein and reducing sugar in P. ostreatus were much higher than the CK, showing that different casing soil fertilization treatments after producing mushroom could increase the yield and quality of P. ostreatus.

平菇(Pleurotus ostreatus)隶属于担子菌门(Basidiomycota)、层菌纲( Hymenomycetes)、侧耳科( Pleurotaceae)、侧耳属(Pleurolus)真菌,别称北风菌、冻菇[1],是目前我国栽培最广泛的食用菌之一。平菇出菇后期,随着培养料中养料的消耗,平菇产量低、菇体质量差、效益低等问题突出,通过覆土可以增加出菇潮次、抑制杂菌生长、提高产量和改善品质等。覆土材料及含水量等不同影响食用菌覆土栽培的产量和品质。平菇栽培后期采用不同营养机质覆土,均能提高平菇产量[2];裴悦珩[3]研究了平菇发酵料覆土栽培,覆土后可以明显增加产量,增强抗病和抗杂能力,提高平菇的品质;杨辉德等[4]研究表明,不同覆土方式对平菇产量影响较大,平菇后期覆土以浅地沟式较好;王……
