| 中文摘要: |
| 综述了国内外在烟草，树木（杨树、柳树、桑树），纤维植物（苎麻、棉花）和蓖麻等非食用植物修复土壤镉方面的研究与应用进展，综合分析其修复能力与经济效益，得出蓖麻和苎麻的修复效果最佳。针对严格管控类耕地土壤镉修复，提出了开展非食用植物修复大田试验示范、研发环境友好型辅助措施、优化种植结构调整生态补偿机制，以及及时开展耕地土壤环境质量类别动态调整等建议。 |
| 英文摘要: |
| This article summarized the progress of research and application of non edible plants such as tobacco, trees (poplar, willow and mulberry), fiber plants (ramie, cotton) and castor in the remediation of cadmium contaminated soil domestic and overseas, comprehensively analyzed their remediation abilities and economic benefits, and concluded that castor and ramie had the best remediation effects. In view of the remediation of cadmium contaminated soil in strictly controlled farmland, it suggested carrying out field experiment and demonstration of the remediation by non edible plants, developing environment friendly auxiliary measures, optimizing planting structure adjustment ecological compensation mechanism, and dynamically adjusting farmland soil environmental quality category in time. |
