摘　　要：薇甘菊可持续性管理是保护生态安全的必要措施,利用植物替代种植防控薇甘菊是一种新战略。为发掘可替代种植防控薇甘菊的植物及有效替代种植模式,对不同播种密度下7种草本植物和5种林木与薇甘菊混合种植的防治效果进行对比研究。研究结果表明,以3 000粒/m2的密度混合种植下薇甘菊的主茎长度、分枝数和生物量柱花草分别是0.88m、0.48枝和0.06g;东非狼尾草则分别是0.79m、0.93枝和0.07g;勃氏甜龙竹混合种植薇甘菊盖度为0.00%。上述数据与对照均存在显著差异,说明利用植物(如柱花草、东非狼尾草和勃氏甜龙竹)进行替代种植,可以有效防治薇甘菊。采取林木-草本混种的方式将是一种更为有效的薇甘菊替代种植技术模式。Sustainable management of Mikania micrantha was necessary for ecological safety,and alternative planting technology though utilizing native plants is a new strategy for sustainable management of M. micrantha. A field test was carried out for exploring effective replacement plant,and five species of xylophyta and seven species of herbage were mixed plant respectively with M. micrantha under three different seeding rates. The results were found that grass height,branching number and biomass were 0. 88 m,0. 48 and 0. 06 g respectively in Stylosanthes humilis treatment（ seeding rate was 3 000/m2）,and 0. 79 m,0. 93,0. 07 g respectively in Pennisetum clandestinum treatment,the cover degree of M. micrantha was 0. 00% in Dendrocalamus brandisii treatment. The results were significant difference compared with control treatment,and this implied that alternative planting technology though utilizing native plants（ S. humilis,P. clandestinum and D. brandisii） were effective for control of M. micrantha.
