%X Effect of continuous submerging and wetting-redrying on cadmium speciation and uptake by Sorghum hybrid Sudangrass in a Ferric-accumulic Stagnic Anthrosol and a Tipical Hapludult collected from the Taihu Lake region and the rolling downs of Yingtan,Jiangxi,China respectively,was studied by pot experiment with Cd spike in 2003.Compared to that under wetting-redrying treatment,the MgCl2-extracted pool of Cd in Huangnitu with spiked Cd of 5mg·kg-1 and 10mg·kg-1 was decreased from 21.8% and 28.5% to 8.0% and 16.9% while NH2OH·HCl-extracted pool increased from 17.7% and 17.3% to 28.1% and 37.5% under continuous submerging.However,in the Typical Halpudult,NaAC-extracted pool of Cd decreased from 20.8% and 29.6% to 11.6% and 12.6%.Cd uptake by Sorghum hybrid Sudangrass was found in negative correlation with the MgCl2 extracted pool of Cd.Total Cd uptake was significantly reduced by the pretreatment of continuously submerging in Huangnitu.
