农用地土壤重金属污染调理剂及叶面阻控剂集成技术的筛选研究

Study on Screening of Integrated Technology for Heavy Metal Pollution Regulators and Leaf Surface Inhibitors in Agricultural Land Soil

本研究通过施用不同土壤调理剂、叶面阻控剂,并将其合理组合,分析其对农作物重金属含量的影响。结果表明,相比单一处理,集成处理效果普遍更优。其中,处理组T12对试验区土壤具有较好的修复效果,可降低水稻籽粒中重金属镉、汞的含量;处理组T4会增加水稻籽粒的汞含量,因此腐殖酸可能不适用于土壤重金属汞污染的修复。

By applying different soil conditioners and leaf inhibitors,and combining them reasonably,their impact on the heavy metal content of crops is analyzed in this study.The results indicate that compared to single processing,integrated processing is generally more effective.Among them,treatment group Tiz has a good remediation effect on the soil in the experimental area,which can reduce the content of heavy metals such as cadmium and mercury in rice grains;treatment group T4 can increase the mercury content in rice grains,so humic acid may not be suitable for the remediation of heavy metal mercury pollution in soil.
