稻田土壤重金属赋存形态·运移规律及灌溉的影响

Chemical Forms and Migration of Soil Heavy Metals in Paddy and Effects of Irrigation

简述土壤重金属赋存形态及影响因素,水稻植株对土壤重金属的吸收、分布和富集,以及土壤重金属运移及其影响因素的研究进展。针对不同灌溉导致的稻田土壤环境和水稻生长吸收功能等差异,提出不同灌溉模式下稻田重金属迁移转化规律有待研究的问题。

The chemical speciation of heavy metals and its factors,heavy metals aborted and accumulated by rice plants,soil heavy metals migration and its factors were reviewed.Efficient irrigation led to huge changes in paddy soil environment,which would contribute to metals binding forms and its migration in soil-plant system.Migration and conversion of heavy metals in rice paddy with different irrigation should be further studied.
