中文摘要:
      如何降低水稻中镉(Cd)的含量已经成为一个研究热点。在湖南省衡阳县某地受轻度镉污染的农田上种植两季水稻(早稻、晚稻),随机采购市场上销售的阻控剂(石灰、硅肥和叶面锌肥),研究这3种类型阻控剂对水稻富集镉及稻谷中镉含量的影响,这3种类型的阻控剂的施用方式是石灰和硅肥作为基肥施于土壤,叶面锌肥通过叶面喷施。结果表明:与没有施加阻控剂相比,除石灰和晚稻锌处理之外,其他处理增产效果显著。在3种类型的阻控剂中,叶面锌肥对籽实富集镉的阻控效果最佳,分别使早稻Y俩优792和晚稻农香130降低了51.28%和50.92%,基施硅肥阻镉效果次之。田间试验结果进一步表明施硅肥和喷施叶面锌肥可作为当地的水稻镉污染阻控剂,但叶面锌肥与稻谷中镉的交互作用需要更深入的探讨。
英文摘要:
      How to control cadmium (Cd) pollution in rice grain has become a hot research issue. The effects of the three amendments such as lime, silicon fertilizer and zinc foliar fertilizer from local market on the accumulation Cd in rice grain including early rice and later rice growth in one Cd-contaminated field in Hengyang County, Hunan Province were studied. Among the three treatments, the silicon fertilizer and lime were applied into soil, and the zinc fertilizer was sprayed on the leaf of rice plant. The results showed that, except lime and zinc fertilizer(late rice), in comparison to nonamendment, the output of early rice and late rice increased with increasing of the other types of resistances. Among three kinds of resistances, the zinc foliar fertilizer had significant impacts on decreasing Cd in edible grains, in which Cd concentrations of early rice(Y-liangyou 792) and late rice(Nongxiang130) reduced by 51.28% and 50.92%, respectively, followed by silicon fertilizer. The present study demonstrated that the silicon fertilizer and zinc foliar fertilizer would be used as resistances for remediation Cd-polluted rice plant, moreover, the relationship between Zn and Cd in rice-soil would need further studied.
