Heavy metals are non-degradable,they exist in the soil environment for a long time,seriously affecting the safety of crops.The sulfhydryl-modified attapulgite (ATP-SH) was added to the soils with different Cd pollution levels to conduct potted rape experiments,and the available Cd in soil and Cd in different parts of rape were determined by graphite furnace atomic spectrometry.The correlation among the addition amount of ATP-SH,the available Cd in soil,and Cd in different parts of rape were discussed by SPSS.The bioconcentration factors and translocation factors of Cd in rape were calculated,the passivation effect of ATP-SH on soil Cd and its effect on the bioconcentration and translocation of Cd in rape were studied.After adding ATP-SH,the available Cd in soil and Cd in different parts of rape significantly reduce,variation range of available Cd reduction rate in soil are 40.65%~74.27%,and variation range of available Cd reduction rate in rape root,stem,limb and rapeseed were 29.36%~79.46%,41.44%~88.45%,43.19%~95.89% and 38.02%~95.81%,respectively.The addition of ATP-SH has significant or extremely significant negative correlation with available Cd in soil and the content of Cd in all parts of rape.There are significant or extremely significant positive correlation between soil available Cd and the content of Cd in all parts of rape.There are significant positive correlation among the content of Cd in all parts of rape.In the control group,the bioconcentration factors of Cd in rape roots,stems,limbs and rapeseed respectively are 1.42~4.87 times,1.71~8.66 times,1.92~24.43 times and 1.61~23.76 times higher than that of the experimental group.The order of translocation factors of Cd in rape is sti>limb>rapeseed,the translocation factors of Cd in stem are 3.5~25 times higher than that in limb and rapeseed.ATP-SH can reduce the activity of soil Cd and effectively prevent the migration of Cd from soil to rape.
