[Objective] The theoretic guidance for the control of the Sclerotium rolfsii in Coptis chinensis Franch in production was provided through the research on the condition, damage and principle of its occurrence. [Method] The investigation in field, the periodical statistics of disease occurrence and its damage was conducted. [Results] There were high rate of disease occurrence and complex affecting factors. The growth duration, age of plant, elevation, cropping system, slope, type of soil and other ecological environments affected the disease occurrence. [Conclusion] The Sclerotium rolfsii was one of important diseases affecting Coptis chinensis Franch production.%[目的]掌握黄连白绢病的发病条件、危害程度及发病规律,为生产上白绢病毒的科学防控提供理论指导.[方法]通过一般性走访调查,了解白绢病发生情况,并采取样地田间调查研究的方法,定期统计发病率及危害程度,分析相关影响因子.[结果] 黄连白绢病发病率高,影响因素复杂,生长期、植龄、海拔、耕作制度、坡度、土壤类型及周围生态环境等因素均对黄连白绢病的发生有重要影响,危害重者发病率可达30.0%,并造成减产乃至绝收. [结论]黄连白绢病已成为影响黄连生产的重要病害.
