[目的]研究植物对 Cd污染土壤的修复效果。[方法]采取模拟和实地试验，通过种植黑麦草，研究植物对污染场地土壤的修复效果。[结果]在洗脱后的土壤中种植黑麦草0~60 d，土壤中 Cd含量呈现快速下降的趋势，60 d后植物对 Cd的富集能力随种植时间增长逐渐减弱，在植物修复75 d后土壤中的 Cd含量大大降低，修复效率为90.66%。[结论]黑麦草修复技术对 Cd污染土壤具有较好的修复效果。

Objective] The remediation effect of the plant to Cd-contaminated soil was studied. [Method] By taking simulation test and field test, the ryegrass (Lolium perenne L.) was planted, and the remediation effect of the plant to contaminated sites was studied. [Result] The ryegrass was planted in the eluotropic soil for 0-60 d, Cd content in the soil showed a rapid decreasing trend; after 60 d, the enrich-ment ability of the plant to Cd gradual y weakened over time; after 75 d of phytore-mediation, the Cd content in the soil decreased greatly, and the remediation effi-ciency was 90.66%. [Conclusion] Ryegrass remediation technology had good reme-diation effect to Cd-contaminated soil.
