摘要: 为筛选适宜在鄂东地区镉(Cd)污染农田种植的镉低积累水稻(Oryza sativa L.)品种,以10个中晚籼型镉低积累水稻品种为研究对象,以当地2个主推杂交稻品种为对照(CK),在大冶市典型镉污染稻田开展田间试验,系统探究参试品种的降镉潜力、产量表现及糙米微量元素(铁、锰、锌)的吸收特征。结果表明,10个镉低积累品种的糙米镉含量为0.011~0.078 mg/kg,均显著低于对照品种(P<0.05),且低于国家食品安全标准限量值,表现出镉低积累特性,且糙米中砷、铅、铬、汞等重金属含量均符合国家食品安全标准限量要求。在产量方面,参试品种整体表现好,其中杂交稻臻两优8612产量最高,达9 947.9 kg/hm2,常规稻康稻3号和康稻6号产量表现稳定。营养元素分析显示,镉低积累品种在维持糙米镉低积累的同时,糙米铁、锌含量并未显著降低,部分品种甚至高于对照品种;相关性分析发现,糙米镉含量与锰含量呈极显著正相关(P<0.000 1),与铁、锌含量相关性不显著。综上所述,参试10个镉低积累水稻品种在鄂东镉污染稻区均能实现安全生产且产量可观,具有良好的推广应用前景。

Abstract: In order to screen low-cadmium accumulation rice (Oryza sativa L.) varieties suitable for planting in cadmium (Cd)-contaminated farmland in Eastern Hubei Province, 10 medium-late indica rice varieties with low accumulation of Cd were used as research objects, and 2 local hybrid rice varieties were used as the control (CK). Field experiments were carried out in typical Cd-contaminated paddy fields in Daye City to systematically explore the cadmium reduction potential, yield performance and uptake characteristics of trace elements (iron, manganese and zinc) in brown rice of the tested varieties. The results showed that the cadmium content in brown rice of 10 low cadmium accumulation varieties was 0.011~0.078 mg/kg, which was significantly lower than that of the control varieties (P<0.05) and also lower than the national food safety standard limit value, showing the characteristics of low cadmium accumulation, and the contents of heavy metals such as arsenic, lead, chromium and mercury in brown rice all met the national food safety standard limit requirements. In terms of yield, the overall performance of the tested varieties was good, among which the yield of hybrid rice Zhenliangyou 8612 was the highest, reaching 9 947.9 kg/hm2, and the yield of conventional rice Kangdao 3 and Kangdao 6 was stable. Nutrient element analysis showed that low-cadmium accumulation varieties maintained low cadmium accumulation in brown rice, while the content of iron and zinc in brown rice did not decrease significantly, and the content in some varieties was even higher than that of the control varieties. Correlation analysis showed that cadmium content in brown rice was significantly positively correlated with manganese content (P<0.000 1), but not significantly correlated with iron and zinc content. In summary, the 10 low-cadmium accumulation rice varieties could achieve safe production and considerable yield in the cadmium-contaminated rice area of Eastern Hubei Province, demonstrating good application prospects.
