Cadmium Accumulation in Soybean Crops in Contaminated Soil

Biological enrichment of cadmium ion was studied in mature soybean plant's different organs to judge cadmium ion's influence on soybean plant's growth and quality.The cadmium ion's content in soil,the soybean root,stem,leaves,shells,and soybean core was tested.The experiment showed that different organs of soybean plant had different ability to absorb cadmium ion.The root absorbing ability was in superior while straw in the second place.Leaf and fruit absorbed less cadmium than the former two organs.For soil which polluted by heavy metals cadmium,soybean plant had function of good bioremediation.
