摘　　要：采取标准样地调查法对湖南省主要油茶产区(耒阳、常宁、浏阳)的不同类型油茶林的油茶病害进行了逐月调查。调查显示,危害湖南省油茶种植的病害有油茶炭疽病、油茶软腐病、油茶根腐病等7种主要病害,这些病害的发生和危害程度有明显的季节性。通过对苗圃地、新造林、幼林、成林、采穗圃、老林和低改林等不同类型油茶林的对比调查,总结了不同类型油茶林的病害发生特点,为及时准确防治油茶病害提供了科学依据。By using standard sample method, an investigation was conducted on the disease in the different types of Ca- rneUia oleifera forest in main producing areas in Hunan Province （for example, Lciyang, Changning and Liuyang） . Sur- vey showed that there were seven major diseases in Hunan Province such as Colletotrichum gloeosporioides, Agaricodochi- urn camellia, Sclerotium rolfsii and so on.

Through investigation of different types of Camellia oleifera forest, such as nursery, reforestation, young growth, ma- ture forest, scion, old forest and low-yield forest, the occurrence characteristics of the main disease in different types of Camellia oleifera forest were summarized, and it should provide a scientific basis for timely and accurate prevention on these disease.
