　　为了研究不同品种及类型杂交水稻对重金属Cd、Zn和As吸收累积差异，在湘南某矿区重金属和As复合污染稻田中种植30种不同品种的杂交水稻。研究结果表明：30个杂交水稻中糙米Cd含量为0.28~0.83 mg/kg，Zn含量为24.13~34.16 mg/kg，无机As含量为0.45~0.77 mg/kg。不同基因型杂交水稻品种吸收累积重金属Cd、Zn和无机As有一定的差异性，Cd在不同水稻品种糙米中的积累存在显著差异性，而Zn和无机As在水稻糙米中的累积差异性不显著。不同类型的杂交水稻之间对于重金属的累积也存在差异性，两系杂交水稻和三系杂交水稻糙米中Cd含量存在显著差异(P<0.05)，而糙米中Zn和无机As的含量差异性不显著。因此，根据不同基因型杂交水稻对重金属累积的差异性，筛选出重金属低累积水稻品种的方法是可行的。

In order to research the difference of Cd, Zn and As accumulation in different hybrid rice cultivars, 30 different hybrid rice cultivars were cultivated in a heavy metal and arsenic polluted paddy field which located in a mine zone of southern Hunan Province. The results showed that:there were certain differences of accumulation Cd, Zn and inorganic As between different genotypes of hybrid rice cultivars. The brown rice contents of Cd, Zn and As in 30 different hybrid rice cultivars were 0.28-0.83, 24.13-34.16, 0.45-0.77 mg/kg, respectively. Cd accumulation in brown rice of different genotypes of hybrid rice cultivars has significant difference, while Zn and As accumulation in brown rice is small differences. The significant difference of Cd content in brown rice exist between the two-lined hybrid rice and three-lined hybrid rice (P<0.05), and the differences of Zn and As contents in brown rice was not significant. Therefore, depending on differences of heavy metals accumulation in different hybrid rice cultivars, it indicated that the selection the pollution-safe cultivars were possible.
