%X 通过在轻度污染耕地的田间试验&#65292;试验选取9种不同玉米品种和6种不同大豆品种对重金属As、Cd的吸收差异进行分析&#65292;并探讨玉米和大豆对As、Cd的转运规律&#65292;以期筛选出对As、Cd低积累玉米和大豆品种。本研究评估了九种玉米品种和六种大豆品种籽粒中砷(As)和镉(Cd)浓度&#65292;结果显示&#65292;这些品种的污染物浓度均符合GB2762-2022《食品安全国家标准&#8212;&#8212;食物中污染物限量》要求。通过分析各品种的转运系数&#65292;发现As和Cd的根部到籽粒的平均转运系数分别为0.0011和0.0056&#65292;均低于1&#65292;表明污染物在作物中的积累较低。此外&#65292;各品种的产量较高。试验初步推荐MC807、郑单952和郑豆1307为该区域受污染耕地的低累积农作物品种&#65292;具有较好的安全利用前景。<br>This study investigated the absorption and transport of arsenic (As) and cadmium (Cd) in nine maize and six soybean varieties through field trials on mildly contaminated soils. The aim was to identify maize and soybean varieties with low accumulation of As and Cd. Results showed that the concentrations of As and Cd in these varieties were within the limits set by GB2762-2022 &#8220;National Food Safety Standards&#8212;Limits of Contaminants in Food&#8221;. The transfer coefficients from root to grain for As and Cd were 0.0011 and 0.0056, respectively, both below 1, indicating low accumulation of these metals in the crops. Additionally, the varieties exhibited high yields. Based on these findings, MC807, Zhengdan 952, and Zhengdou 1307 are recommended as low-accumulation crop varieties for the safe utilization of contaminated lands in this region.
