摘要:
水稻对镉的富集存在显著的品种差异。在土壤镉高背景值区,如果盲目种植容易引起健康风险。采用盆栽试验研究广西常见的6个水稻品种(丰源优219、深优957、宜香305、桂丝粘、中广香1号、百香139)对镉的累积差异。结果表明,在高镉(0.43 mg/kg)背景值土壤中,6个品种的水稻糙米镉累积水平差异显著,糙米镉浓度大小依次为中广香1号<深优957<丰源优219<百香139<桂丝粘<宜香305。其中,桂丝粘、宜香305糙米镉浓度是国家食品标准临界值的2.35、2.50倍,存在较大的健康风险。中广香1号糙米对镉的累积最低,为(0.16±0.03)mg/kg,且显著低于其他品种(P<0.05),按推算该品种糙米镉浓度满足食品安全要求不影响人体身体健康。由于中广香1号与其他5个品种比较,产量无显著差异,糙米对土壤镉的富集系数最低。可见,中广香1号是比较适合广西镉高背景值区种植的低累积品种。
