少花蒺藜草入侵风险评估及其防控策略

少花蒺藜草（Cenchrus pauciflorus Benth.）是一种恶性入侵植物,已在辽宁省西北部、内蒙古自治区东部、吉林省南部三省交会地区广泛传播扩散,给当地农事生产活动及畜牧业生产带来了严重危害。通过阐述少花蒺藜草的生物生态学特性及对其入侵风险的评估,指出少花蒺藜草在我国的适生面积广,传播扩散能力强,防控难,旨在建议应进一步加强少花蒺藜草的防控研究,根据其危害机理及生态经济效益,对其坚持施行生态、经济、有效的整体防控和长期监控策略。

Risk Assessment and Control Utilization Strategies of Cenchrus Pauciflorus Benth.

Cenchrus pauciflorus Benth.is a malignant invasive plant,which has widely diffused in the northwestern of Liaoning,the eastern of Inner Mongolia and the southern of Jilin,and has engendered serious harms to the local agriculture and animal husbandry production.Through describing bio-ecological characteristics of Cenchrus pauciflorus Benth.and analyzing its invasive risk,it indicates that Cenchrus pauciflorus Benth.has a wide suitable developable area and a strong spread ability in our country,and it is very difficult to prevent and control the diffusion of it,and then point out that the technology study on prevention and control of Cenchrus pauciflorus Benth.should be further strengthened.According to harm mechanism and eco-economic benefits of Cenchrus pauciflorus Benth.,the integrated technology and the long-term monitoring were applied to prevent and control the diffusion of Cenchrus pauciflorus Benth,which are ecological,economical and effective.
