摘　　要： [目的]研究南美蟛蜞菊在稀土矿中的生长情况,为矿区植被恢复与重建工作提供技术支撑。[方法]以南美蟛蜞菊为材料,采用先在实验室盆栽扦插后在稀土矿废弃地进行栽培的方式,研究南美蟛蜞菊在普通土壤和稀土矿废弃地的生长差异。[结果]南美蟛蜞菊在稀土矿废弃地里能正常生长,其茎段拥有发育成一个完整植株的能力,在种植前期保证充沛的浇水量能够让蟛蜞菊快速生长。[结论]南美蟛蜞菊在稀土矿废弃地有良好的生长适应性,适宜在稀土矿废弃地上栽培与应用。 [ Objective ] The research aimed to study the growth of Wedelia trilobata planted in the abandoned land of rare earth mine, and to pro- vide technological supports for the recovery and reconstruction work of mine vegetation. [ Method] W. trilobata was planted in the pot by cutting in the laboratory at first,and then it was planted in the abandoned land of rare earth mine. The growing difference of W. trilobata planted in the common soil and in the abandoned land of rare earth mine was compared. [ Result] The results showed that W. trilobata was able to grow normal- ly in the rare earth and the stem section had ability of developing into a complete plant. With enough water, W. trilobata could grow quickly in the early stage. [ Conclusion] IV. trilobata had good adaptability in the abandoned land of rare earth mine. And it was fit for planting in the aban- doned land of rare earth mine.
