摘    要:在厦门市鼓浪屿受外来入侵植物猫爪藤危害严重地段,开展了人工清除结合生态替代根除猫爪藤的研究。结果表明:猫爪藤具有很强的无性繁殖能力,大于10 g重的块根成活率达100%。地下部生物量有97.1%集中在地表0~40cm土层中。采取清除地上部分,并挖除地下40 cm深根系的方法,1年后株防效达71.5%。为防止地下残存块根的再次萌发扩展,人工清除后种植白蝶合果芋、细叶萼距花形成密集植被可限制猫爪藤萌生和生长。每年3~6月是防除猫爪藤的最佳时间。

关 键 词:杂草防治  猫爪藤  生物入侵  生态替代

Abstract:Experiments on control of invasive plant Macfadyena unguis-cati with ecological substitution have been performed in the place located in the Gulangyu Island in Xiamen, where is seriously damaged by Macfadyena unguis-cati(L.) A.Gentry. The result shows that M. unguis-cati has strong asexuality reproduce capacity. The roots of M. unguis-cati,which weigh more than 10 g,can germinate 100 percentage. 97.1 percentage of the biomass below-ground concentrates on the earth from 0 cm to 40 cm. Hand control is proved effective to some extent which is to exterminate the above-ground part completely and the below-ground roots to 40 cm depth. To avoide the regrowth of the survival below-ground roots, the ecological substitution is necessary. After removing, the regeneration of M. unguis-cati could be prevented by planting other plants by occupying the space, such as Syngonium podophllum and Cuphea hyssopifolia. The best time to control and remove M. unguis-cati is from March to June every year.
Keywords:weed control  Macfadyena unguis-cati  invasive species  ecological substitution
