三种类型阻控剂对不同品种水稻富集镉的影响
Effects of Three Inhibitors on the Accumulation of Cadmium in Rice(Oryza sativa L.)
摘要
Abstract
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.关键词
