摘　　要：通过在内蒙古中部轻度重金属污染农田中施用5种土壤调理剂、5种微生物菌剂,比较重金属在土壤、玉米籽粒中的积累情况和对玉米产量的影响,筛选可降低土壤和玉米籽粒重金属含量的适宜土壤调理剂和微生物菌剂。结果表明,试验中的土壤调理剂和微生物菌剂均降低了土壤中重金属的含量,其中土壤调理剂对玉米籽粒中砷含量、微生物菌剂对玉米籽粒中镉和砷含量的降低效果较好,有3种土壤调理剂和2种微生物菌剂处理增加了玉米产量。综合考虑,江苏天象、南京宁粮两种土壤调理剂和迈科珍微生物菌剂在降低土壤、玉米籽粒重金属含量和增加玉米产量方面效果较好,建议在该地区进一步探索研究。By applying five kinds of soil conditioners and five kinds of microbial agents to the corn field slightly polluted by heavy metals in central area of Inner Mongolia,the accumulation of heavy metals in soil and corn grains and their effects on corn yield were compared,and the suitable soil conditioners and microbial agents were selected to reduce the heavy metals in soil and corn grains.The results showed that all the soil conditioners and microbial agents in this test reduced the contents of heavy metals in soil,the soil conditioners had better effects on reducing the As content in corn grains,the microbial agents had better effects on reducing the Cd and As contents in corn grains.3 kinds of soil conditioners and 2 kinds of microbial agents increased the corn yield.All above considered,2 kinds of soil conditioners(Jiangsu Tianxiang,Nanjing Ningliang)and 1 kind of microbial agent(Maikezhen)had better effects on reducing the contents of heavy metals in soil and corn grains and increasing corn yield,which could be further explored and studied in this area.
