喜旱莲子草[Alternanthera philoxeroides(Mart.)Griseb]在农业上可以作为饲料、肥料、栽培食用菌、制作沼气,并用于水稻育种;在污染治理上的主要应用在净化水体、富集重金属上;在医药上主要应用在抑菌、抗病毒、护肝、抗肿瘤上。笔者综述了近年来国内外对喜旱莲子草利用和研究的进展,并对其未来利用进行了展望。

Alternanthera philoxeroides（ alligator weed） is an invasive weed that can colonize both aquatic and terrestrial habitats and tolerate high concentration of salt. It grows quickly and invades almost all temperate and tropical areas of the world,including most provinces of South China. A. philoxeroides is one of the first batches of invasive species that cause serious damage. The progress on utilization and study of A. philoxeroides in recent years is reviewed. A. philoxeroides can be used in agriculture as raw material for fodder and fertilizer,mushroom cultivation,production of biogas,and rice breeding,in pollution control for water purification and accumulation of heavy metals,and in medical sciences as antibacterial,antiviral,liver-protecting and anti-tumor medicines.Meanwhile,future prospect on utilization of A. philoxeroides is discussed as well.
