摘　　要： 为了研究野地瓜促进富集植物黑麦草吸收重金属镉的可能性,笔者通过盆栽试验的方式对比了不同处理中黑麦草地上部分重金属镉的含量。试验结果表明:套种野地瓜处理的黑麦草地上部分总镉含量为每盆5.6439×10^(-3)mg,而单独种植黑麦草处理组的黑麦草地上部分总镉含量为4.6164×10^(-3)mg,相比之下,增加了1.0275×10^(-3)mg,增加率为22.26%。野地瓜套种黑麦草能有效的促进黑麦草对重金属镉的吸收。本研究为促进富集植物对重金属的吸收提供了一种新的思路与途径。 To study the possibility of using Ficus tikoua Bureauto to promote Cd absorption by perennial ryegrass, a pot experiment was conducted, and the Cd content in the overground part was compared in differenttreatments. The results showed that the Cd content of perennial ryegrass was 5.6439×10^（-3）mg of per pot when itwas interplanted with Ficus tikoua Bureauto and that of CK was 4.6164 × 10^（-3）mg, indicating that the interplanting could increase Cd content of perennial ryegrass by 1.0275×10^（-3）mg of per pot, the increase ratewas 22.26%. It is concluded that the interplanting could promote the Cd absorption of ryegrass. The studyprovides a new way to promote the absorption ability of phytoremediation.
