【中文摘要】 对四个香菇开放式接种场所内不同时间点环境中霉菌和细菌的数量、温度和湿度进行测定,结果表明,在同一测试场所,不同测试时间点环境中霉菌和细菌的数量有所变化。总体上,消毒前和接种结束时环境中霉菌和细菌的数量相对较多,接种开始和接种进行一半时环境中霉菌和细菌的数量较少。各场所环境中的温度、湿度与霉菌和细菌的数量无相关性。消毒前环境中霉菌、细菌数量与菌棒污染率成正相关,相关系数分别为0.83和0.96;接种开始时环境中霉菌、细菌数量与菌棒污染率的相关系数分别为0.64和0.94;接种进行一半和接种结束时环境中的霉菌数量与菌棒污染率无相关性,而这两个时间点细菌数量与菌棒污染率的相关系数分别为0.62和0.88。
【英文摘要】 Fungal and bacterial counts,and temperature and humidity values,were determined in four separate inoculation rooms used to inoculate artificial sawdust logs with Lentinula edodes(without using an inoculation box)both prior to sterilization of the rooms and at different times during the inoculation period.Higher fungal and bacterial counts were recorded before sterilization and when inoculation activities had been completed compared with the beginning and middle of the inoculation period.Our data revealed no evidence of a link between fungal and bacterial counts and relative humidity.Prior to sterilization,positive correlations were observed between both fungal and bacterial counts and log contamination rates(correlation coefficients:0.83 and 0.96,respectively).At the start of the log inoculation period,these correlation coefficient values were 0.64 and 0.94,respectively.No correlation between fungal counts and log contamination rates was evident both halfway through and at the end of t...更多he log inoculation period.However,a positive correlation was observed between bacterial counts and log contamination rates at these two sampling times(correlation coefficients:0.62 and 0.88,respectively). 还原
