摘要
针对中国南方重金属超标农田污染治理技术特点作了简要分析与探讨,并收集汇总中国现有镉、砷、铜和铅的超积累植物40种,同时进行了分类与归纳。依据中国现有的重金属超积累植物,讨论了中国南方重金属超标农田修复植物的筛选和培育方向,分别给出对重金属镉、砷、铜和铅的污染修复超积累植物应用建议及相关理论依据。
This paper briefly analyzed the characteristics of the control technologies of heavy metal pollution in farmland in southern China.40 species of hyperaccumulators for cadmium,arsenic,copper and lead in China were collected,classified and summarized.Based on the existing heavy metal hyperaccumulators in China,the selection and cultivation direction of remediation plants in farmland with excessive heavy metals in southern China were discussed.Suggestions for the application of hyperaccumulators in the remediation of farmland with heavy metal cadmium,arsenic,copper and lead pollution were put forward.
