摘　　要：随着工农业生产的发展,土壤环境问题日益严峻,据2014年的《全国土地污染状况调查公报》显示,全国耕地土壤的超标率为19.4%,其中的主要污染物为镉、镍、铜、砷、汞、铅等重金属元素,重金属污染问题亟待解决。在土壤环境研究中,根系土作为一项重要的研究对象,对土壤环境研究尤其是农作物土壤具有重要意义。With the development of industrial and agricultural production,soil environmental problems are increasingly serious.According to the 2014 National Land Pollution Survey Bulletin,the over-standard rate of arable soil in the country is 19.4%,and the major pollutants are cadmium,nickel,copper,arsenic,mercury,lead and other heavy metal elements.The problem of heavy metal pollution needs to be solved urgently.In the study of soil environment,root soil,as an important research object,is of great significance to the study of soil environment,especially crop soil.
