烟草上列当的发生与防治措施研究进展

Advances on occurrence and control measures of parasitic Orobanche of tobacco

寄生性杂草是世界范围内农业生产中最具毁灭性的灾害之一。列当是寄生植物中危害最重的根寄生杂草。列当寄生烟草后严重影响烟叶产量和品质,在我国列当对烟草的危害有上升趋势,因此应该引起高度重视,积极加强对烟草上列当的生长特征、理化遗传特征、流行扩散动态和防治措施的研究和应用。本文综述了近年来我国烟草列当的发生和蔓延趋势,讨论了不同防治方法的优缺点,为列当新型防治方法的研究奠定基础。

The parasitic weed is one of the most devastating disaster for the agricultural production all over the world. Orobanche is regarded as the most serious root parasitic plant among parasitic weeds. The production and quality of tobacco with parasitic Orobanche have been influenced heavily and showed an upward trend, for which should be paid more attention. Besides, the research and application of physical and chemical characteristics, growth characteristics, dynamic development and prevention and control measures of Orobanche should be actively enhanced for advanced tobacco leaves production. The occurrence and expanding trend of parasitical Orobanche recently were reviewed in this paper and advantages and disadvantages of different control strategies were discussed later, which would lay the foundation of for exploring effective control measures of parasitical Orobanche on tobacco.
