西藏青稞白粉病研究进展与展望

Research Status and Prospect of Tibetan Highland Barley Powdery Mildew

青稞是西藏最大的优势特色作物,从青稞基础研究、青稞育种、青稞示范推广、青稞加工等方面开展深入科学研究是保障西藏青稞安全的基础。西藏青稞白粉病发生普遍,主要在每年雨季来临后,大约6月底出现,7月盛发期,主要危害植株下部叶片。本文简要叙述了西藏青稞白粉病发生情况,综述了青稞白粉病方面相关研究内容及进展,对西藏青稞白粉病的研究工作具有理论意义。

Barley is the largest dominant crop in Tibet. Carrying out in-depth scientific research on the basic research, breeding, demonstra- tion and promotion of barley, and barley processing is a prerequisite to ensure the safety of barley, the largest dominant crop in Tibet. Tibet- an barley white powder disease, mainly harming lower leaves of the plant, occurs commony, especially after tire arrival of the rainy season each year. Approximately, it appears at the end of June, and reaches peak period in July. Here we briefly describes the situation of Tibetan barley powdeU disease and reviewes the related research contents and progression which have the theory significance for Tibetan barley pow- dery disease research.
