To explore the remediation methods of lightly cadmium(Cd)polluted paddy fields，a plot experiment was carried out for two conseartive years with Tianxiang soil conditioner(TX)，straw carbon materials(JGT)and three kinds of Sammns nanometer materials(SAX1，PX4，WH4P)，near a mining area in Tongling，Anhui. The effects of the five soil conditioners on the available Cd content，soil pH，and grains Cd content of the current year in lightly Cd-polluted paddy fields were compared with the next year.Results showed that，in the first year，with the application of different soil conditioners，soil pH increased by 0.13～0.69 units，while the available cadmium content was significantly reduced by 0.82%～6.93%，among which，PX4 had the largest decline.The content of Cd in rice grains was reduced，and compared to the control group，Cd in rice grains of Zhendao11 and Zhendao18 decreased by 17.77%～57.65% and 11.76%～53.59%，respectively，both PX4 and SAX1 treatments had obvious effect on reducing grain Cd content.The yield of rice increased by 8.73%、14.71% for Zhendao11 while 8.09%、4.53% for Zhendao18 with soil conditioner SAX1 and JGT applied.In the second year，the soil pH increased by 0.11～0.36 units，the soil available Cd content decreased by 5.50%～21.60%，and the WH4P and SAX1 treatments decreased the most. Compared to the control，the Cd content in rice grains decreased，Zhendao11 decreased by 15.31%～41.19%，while Zhendao18 decreased by 17.53%～38.73%，respectively，both varieties had the largest decline in WH4P treatment. Nevertheless，with WH4P treatment，both varieties of rice decreased in yield，Zhendao11 decreased by 1.94%，while Zhendao18 decreased by 0.24%.In general，both PX4 and SAX1 soil conditioners applied in the first season had better remediation effect on local lightly Cd-polluted rice fields，and WH4P soil conditioners had the best effect in the following year.
