在严格管控区Cd污染稻田开展田间试验，探讨淹水灌溉协同石灰和土壤调理剂对土壤Cd的有效性，以及水稻Cd吸收和累积的影响。结果表明：淹水灌溉协同钝化修复技术可有效降低土壤Cd的有效性和水稻Cd的吸收和积累。淹水灌溉协同石灰和调理剂处理下，土壤pH值较对照显著（P＜0.05）提高0.97个单位，且土壤有效态Cd含量以及水稻根、茎和叶片Cd含量较对照分别显著（P＜0.05）降低36.4%、63.0%、80.3%和42.4%，糙米Cd含量降至0.15 mg·kg-1。淹水灌溉协同石灰和调理剂处理还显著抑制Cd向糙米部位的累积。糙米Cd的富集系数和Cd累积量较对照分别显著（P＜0.05）降低67.8%和62.8%。因此，淹水灌溉协同土壤...

A field experiment was conducted in a strictly controlled area of a soil cadmium（Cd）-contaminated paddy field to investigate the effects of flooding irrigation combined with lime and soil passivators on the availability of Cd in soil, Cd uptake, and accumulation in rice. The results showed that flooding irrigation combined with passivators could effectively reduce Cd availability in the soil and Cd uptake and accumulation in rice. The soil pH under the treatment of flooding irrigation combined with lime and soil passivators was increased by 0...
