通过田间试验，研究了石灰+有机肥（LO）、石灰+有机肥+钙镁磷肥（POF）、石灰+有机肥+海泡石（LOS）、石灰+有机肥+钙镁磷肥+海泡石（LOCS）4种复合改良剂对土壤肥力的影响。研究了水稻-油菜（Oryza sativa L.）和Brassica napus L.）轮换制结果表明，混配处理对水稻和油菜产量影响不大，土壤pH值显著升高，土壤DTPA提取态Cd含量和水稻、油菜对Cd的吸收量显著降低。糙米对Cd的吸收显著降低（p
A field experiment was performed to study the effects of mixed amendments, namely lime + organic fertilizer (LO), lime + organic fertilizer + calcium-magnesium phosphate fertilizer (LOC), lime + organic fertilizer + sepiolite (LOS), and lime + organic fertilizer + calcium-magnesium phosphate fertilizer + sepiolite (LOCS), on the availability and uptake of Cd from contaminated paddy soil under a rice-rape (Oryza sativa L. and Brassica napus L.) rotation system. The results showed that the grain yields of rice and rape with mixed amendment-treated were slightly influenced, in that the soil pH significantly increased while the DTPA-extractable Cd content of the soil and Cd uptake by the rice and rape were significantly reduced. The uptake of Cd by brown rice decreased significantly (p
