摘要
综述了不同土壤、肥料与水分等生态栽培条件对水稻镉(Cd)积累的影响。认为土壤类型与土壤p H,有机肥与氮磷钾肥、硅肥、钙肥及其他微量元素肥,以及水分管理等均对水稻镉积累具有明显的影响;淹水是通过影响土壤的各种理化性质来影响土壤镉的生物有效性;合适的栽培方式能在保证水稻产量的同时,减少水稻对镉的吸收与积累。并提出了今后相关的研究方向。
This paper comprehensively elaborates the effect of different soils, fertilizers and watering on rice cadmium（ Cd）accumulation, reviews that many related factors significantly affect the accumulation of cadmium in rice such as the soil type and soil p H,the organic manure, NPK, Si, Ca and other trace elements in fertilizers, and water management, the waterflooding would affect the Cd bioavailability by changing the soil characteristics, and proposes the future related research direction. The appropriate cultivation methods could be used to help ensure the crop yield and reduce the absorption and accumulation by rice.
