摘要
多年生禾本科草本植物李氏禾(Leersia hexandra),起初作为农田杂草备受关注,后因其具有抗旱耐淹耐瘠的生物学特性以及对重金属铬的超富集特性,成为水土保持领域和重金属污染防治领域的研究热点。就李氏禾在土壤重金属污染植物修复上的应用、李氏禾在人工湿地上的应用、李氏禾在水土保持上的应用和李氏禾与农田杂草的控制4个方面进行了综述,并对其今后发展进行展望,以期为该植物的应用提供参考。
Leersia hexandra is a perennial grass of the Poaceae family.As a variety of weed,it has received much concern initially.Therefore,it becomes a research hotspot in the field of water-soil conservation and pollution control of heavy metals for its biological characteristics of resistance to flood and drought,as well as its accumulation characteristics of heavy metal chromium.This paper summarized application of L.hexandra in four fields：phytoremediation,constructed wetland,soil and water conservation,and weed control.Further,it discussed the prospect of aplication of L.hexandra.It is expected to provide a reference for its application.
