摘要
土壤污染具有隐蔽性和滞后性的特点。依靠植物或微生物对污染土壤进行修复的相关方法逐渐成为社会各界关注的焦点,具有绿色、环保、成本低、效果好等优势。要最大程度地提升该方法作用效果,则需要探究重金属超富集植物,充分实现对污染土壤的深层次修复。对于有机污染物而言,根系修复技术已然是改善土壤有机污染问题的有效途径。
Soil pollution has the characteristics of concealment and lag.In recent years,depending on plants or microorganisms to repair polluted soil has gradually become the focus of attention of all walks of life,with the advantages of green,environmental protection,low cost and good effect.In order to improve the effect of this method to the greatest extent,it is necessary to explore the heavy metal super enrichment plants to fully realize the deep remediation of contaminated soil.For organic pollutants,root remediation technology is an effective way to improve soil organic pollution.
