覆土材料对双孢蘑菇产量和品质及采后保鲜的影响OA

Using 100％domestically sourced peat casing soil as the control(CK),two experimental casing materials were prepared by substituting 40％of the domestic peat with either coconut coir(Treatment A)or imported peat(Treatment B)to study the effects of these different casing materials on yield,quality,and postharvest preservation of Agaricus bisporus.The results showed that the moisture contents of CK,Treatment A and Treatment B were 64.3％,71.2％and 79.4％,respectively.There was no significant difference in total yield between the three treatments.Treatment A resulted in similar fruiting body appearance and nutritional composition compared with CK.However,the contents of trehalose,total sugars,and vitamin C of Treatment A were significantly higher than those of CK in the first flush.In the second flush,while protein and total sugar contents in Treatment A were significantly lower than in CK,the levels of trehalose and vitamin C remained significantly higher.Other measured components showed no significant differences between Treatment A and CK.Overall,Treatment A(coconut coir substitution)showed superior performance compared with Treatment B(imported peat substitution).Fruiting bodies of Treatment A casing maintained high postharvest quality during storage.These findings provided a scientific reference for selection of casing materials in A.bisporus cultivation,highlighting the potential of coconut coir as a sustainable partial substitute for peat.
