通过盆栽试验,在铅锌矿区水稻土上研究了赤泥对土壤Pb、Zn和Cd的改良效果、水稻产量及水稻产量构成因子的影响。结果表明,施用低量的0.25%(W/W)赤泥能促进水稻植株的生长和稻谷产量的增加。稻谷产量随赤泥施用量的增加呈先增加后下降的变化趋势,施0.25%(W/W)、0.5%(W/W)、0.75%(W/W)处理的稻谷产量较不施赤泥处理提高了12.04%、6.25%和4.40%。施赤泥对降低作物体内Pb、Zn和Cd的含量有明显效果,均以赤泥施用量较高的1.25%(W/W)处理效果最好,降幅分别达33.77%、9.84%和15.40%,但糙米中的Pb和Cd的含量仍未达食品卫生标准(Pb 0.4 mg kg~(-1),GB14935-1994;Cd 0.2 mg kg~(-1),GB15201-95),锌含量低于...

A pot experiment was conducted to study the effects of red mud on remediation of Pb, Zn and Cd and grain yield and its yield components in lead-zinc mining area. The results showed that application of 0.25% （W/W） of red mud could promote the growth of rice plants and increase rice yield in Pb-, Zn- and Cd-polluted neutral mine soils. Grain yield increased with increasing red mud application and then decreased. Compared with treatment without red mud application, grain yield increased by 12.04%, 6.25% and 4.40% in treatments applied 0.25% （W/...
