以平菇菌株韩CB100为试验材料,接种托拉斯假单胞杆菌后,将子实体置于不同温度、不同湿度、不同CO_2浓度的环境中培养,观察记录发病情况并计算病情指数,研究不同环境条件对褐斑病致病情况的影响。结果表明:不同温度条件下病情指数存在显著性差异,18℃、20℃条件下,子实体发病较重,23℃时发病较轻;70%~80%和90%~100%两个不同湿度条件的褐斑病发病率差异不显著;CO_2含量0.6‰~0.9‰时较0.3‰~0.6‰时褐斑病发生严重,两者差异显著。
Using Pleurotus ostreatus CB100 as test material, after inoculation of Pseudomonas solanacearum, the fruiting bodies were cultured in different temperature, different humidity and different CO 2 concentrations. The incidence and the disease index were observed and recorded, and the effects of different environmental conditions Effect on brown spot disease. The results showed that there were significant differences in the disease index under different temperature conditions. The fruiting body developed more severe at 18 ℃ and 20 ℃, and had less incidence at 23 ℃. Two different humidities, 70% -80% and 90% -100% The incidence of brown spot disease was not significant. The brown spot disease was serious when the content of CO_2 was 0.6 ‰ ~ 0.9 ‰, but the difference was significant.
