覆土施肥处理对出菇后期平菇产量和品质的影响

Effects of Different Casing Soil Fertilization Treatments on Yield and Quality of Pleurotus ostreatus after Producing Mushroom

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。

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.
