从引进到潜在入侵的植物——南美蟛蜞菊

Wedelia trilobata——A species from introduced to potential invasive

对南美蟛蜞菊的起源与分布、形态特征、生物学特性和利用途径进行介绍。通过分析其潜在危害,认为南美蟛蜞菊是潜在入侵危险的植物,并进一步探讨了对南美蟛蜞菊的预防与控制措施。通过探讨其它有害入侵种外来物种的防治经验,建议合理管理南美蟛蜞菊以减少或避免这样的损失;可采用人工或机械、化学防除方法;另外,要加强其生物学生态特性及适应原理的研究,为治理工作提供科学依据。

The origin and distribution, the characteristics of morphological and biological ,and the utilization of Wedelia trilobata were introduced. Its potential damages was studied. Furthermore, the prevent and control measure were discussed. From successfully controlling experience of other exotic plants,W, trilobata were advised to be managed probably to reduce or avoid the loss. Measures of manual, machine or herbicide can be tried. To offer scientific basis for controlling, researches on biological and ecological characteristic of species must be enhanced.
