Abstract: Using corn as experimental material,and using AAS to analyze the content of heavy mental ion in the root,stem and leaf of the corn,the experiments measure the influence of manganese slag on the growth of corn planted in the pot,examine the accumulation of heavy mental iron in the plant.The results show that the height of the corn is soil plant<treated plant<slag plant,the chief accumulation position of Fe iron is root,the max value is 2.347 3×10-5;the chief accumulation position of Cd iron is root;the max value is 3.57×10-7;the accumulation of Cr iron in the root,stem,leaf is almost the same,and the max value is 3.15×10-7.There is a max value of heavy mental iron in the corn seed planted with the slag,and the max value of Mn,Zn,Fe,Cr,Cd respectively reach 1.0×10-5,1.6×10-5,4.0×10-6,3.7×10-7,0.4×10-8.

Key words: electrolytic manganese slag, accumulation, heavy mental ion, corn
