高海拔区域夏秋季双孢蘑菇覆土材料筛选

Covering Soil Material Screening for Summer and Autumn Agaricus Bisporusin High Altitude Region

以双孢菇品种As2796为试材,研究双孢蘑菇覆土材料中添加一定比例的泥炭土、发酵棉籽壳、麦衣等材料后对双孢菇生长的影响。结果表明：添加一定比例的泥炭土、发酵棉籽壳、麦衣等材料后能有效改善覆土结构,出菇快、菇蕾整齐,出菇期分别较对照提前2~7 d。较常规覆土处理增产0.25~1.60 kg.m-2,其中泥炭N-3及综合覆土配料Z-3覆土处理增产率为17.98%及10.67%。

Taking Agaricus bisporus ＂As2796＂as test target,the influence of adding certain proportion of mate rial（e, g. peat soil, fermented cottonseed hulls and wheat hull）into the covering soil was studied. The result showed that：adding certain proportion of peat soil, fermented cottonseed hulls,and wheat hull etc. into the coy ering soil could effectively improve the composition of the covering soil, the growth of the Agaricus bisporus was faster（2- 7 days earlier than CK）, and the mushroom buddings were more uniform. The treated covering soil samples could increase the production for 0.25-1.6 kg.m^2 ;N-3 and Z-3 soil sample could increase production 17.98% and 10.67%,respectively.
