摘 要：
由细丽外担菌引起的油茶茶苞病是油茶主产区分布极为普遍的病害。以广南县人工种植5-65年生的油茶林为研究对象,采取样线和标准地相结合的方法,对林间油茶茶苞病发病株率、病情指数进行调查。结果表明,该病害在高原山区1年发生2次,症状表现为危害子房形成茶桃、危害叶片形成饼状及危害嫩梢形成泡状3种类型。病害的发生与栽培立地条件、经营管理措施、坡位、坡向、树龄等因素密切相关。针对目前高原山区油茶茶苞病的发生现状及特点,提出相应的防治措施。

摘 要：
Gall disease of Camellia oleifera caused by Exobasidium gracile was a prevalent disease in oil tea cultivation in plateau areas. Taking the Camellia oleifera plantation of 5-65 years age in Guangnan county as the research object,and the incidence rate and disease index of Camellia oleifera were investigated by sampling line and standard land method. The results of field investigation showed that in plateau areas,this disease occurred twice a year,with the symptoms galls at ovary,leaf or shoot. The occurrence of the disease was closely related to the site condition of orchard,management measures,slope position,slope aspect and tree age. Aiming at the present disease condition and characteristics, the corresponding measures for disease control and management were proposed.
