摘　　要：近年来黄背木耳病害的发生严重制着四川省食用菌产业的健康发展。但由于目前并没有相对系统的调查研究,成为病害防治上的技术瓶颈。通过对四川省什邡市湔氐镇、中江县玉兴镇、金堂县赵家镇、中江县兴隆镇、金堂县清江镇等地黄背木耳病害种类进行调查,并对普遍发生的疣巴病的发生规律进行了系统调查。结果表明,四川省黄背木耳主要病害有疣巴病、青霉、曲霉、木霉、发网菌、针箍菌等,其中疣巴病在四川省普遍严重发生。所调查的5个黄背木耳主产区中,金堂县赵家镇发病情况最严重,7月份发病率和病情指数分别为96%和66.12%;金堂县清江镇情况较好,7月份发病率和病情指数分别为61%和26.15%;其它调查点处于中间水平。调查还发现,不同品种对疣巴病的抗性不同,其品种抗病性强弱顺序为成都781>琥珀>上海1号。Recently, diseases on Auricularia polytricha had seriously hindered the healthy development of the edible mushroom industry in Sichuan, and it was difficult to be controlled because of lacking of systematic investigations and study. In this paper, the main disease types were investigated and oil scar disease, major disease in A. polytricha were researched systematically. We find that the main diseases in A. polytricha included oil scar disease, PeniciUium sp., Aspergillus sp., Trichoderma sp., Stemonitis sp, Physarella oblonga and so on. Oil scar disease occurred seriously and prevalently in Sichuan. Among the five A. polytricha advocate produce areas investigated, the disease occurred most seriously in the town of Zhaojia country, whose disease incidence and disease index were 96%, 66. 12% in July. Situations in the town of Qingjiang country were much better, whose disease inci- dence and disease index were 61%, 26. 15%. The others were country in intermediate levels. The study also found that different varieties had different disease resistance, and Chengdu781 〉 Hupo 〉 Shanghai No. 1.
