摘要 【目的】明确云南主产茶区茶饼病发生时空并指导其防治。【方法】对云南主产茶区不同海拔、不同品种茶树茶饼病的发生情况进行实地调查。【结果】各茶区茶饼病始发期一般在6月下旬至8月上旬,盛发期为9-10月。同一茶树品种在不同海拔茶区茶饼病危害程度不同,随着海拔的升高其茶饼病危害越严重。在相同海拔茶区,其不同茶树品种茶饼病危害程度也不同。机采茶园和冬季封园且春茶结束后轻修剪的茶园其茶饼病危害较轻,荫蔽度高的茶园茶饼病发生较重。【结论】云南不同茶区不同年份茶饼病始发期和危害程度存在差异,其始发期与危害程度主要取决于环境条件、茶树品种和栽培管理情况。 【Objective】The purpose of this paper is to clarify the time and space of Exobasidium vexans Massee in Yunnan and guide its prevention and control.【Method】The occurrence of Exobasidium vexans Massee was investigated at different altitudes and different varieties in Yunnan tea growing areas.【Result】The beginning period was from late June to early August,and the hazard intensity was from August to December.Exobasidium vexans Massee was less harm in tea garden of machine-picking and light pruning after hand-picking spring tea and winter treatments.Exobasidium vexans Massee was seriously harm in high shade tea garden.【Conclusion】The beginning period and the hazard intensity of Exobasidium vexans Massee were significant differences at different tea growing areas and years.The beginning period and the hazard intensity depend on environmental conditions,tea varieties and cultivation management.
