摘　　要：通过大田镉污染土壤栽培,对薄皮甜瓜不同部位的镉含量和果实品质进行分析。结果表明:参试的12个不同类型薄皮甜瓜果实镉含量均低于《食品安全国家标准食品中污染物限量》GB 2762—2012规定的甜瓜果实中镉的限量指标(0.05mg·kg^(-1)),其中IVF-28果实内镉含量最低,仅为0.015 3 mg·kg^(-1)。镉在甜瓜植株体内的分布规律为基部茎叶>根>上部茎叶>果实,综合果实镉含量和品质性状,筛选出IVF-28为适于重金属镉中度及以下污染区种植的薄皮甜瓜品种。This paper analyzed the cadmium contents in different parts of oriental melon and fruit quality through cultivating melon on the land with cadmium polluted soil.Results showed that in all 12 tested different types of melon fruit,the cadmium contents were lower than that set by The National Food Safety Standards,Limit of Contaminants in Food,GB 2762-2012 requested the cadmium content in melon fruit was 0.05 mg·kg-1.The cadmium content in fruits of IVF-28 was the lowest,only 0.015 3 mg·kg-1.The cadmium distribution in melon plant was:base stem and leaf>root>upper stem and leaf>fruit.Integrating cadmium content and fruit quality traits,we screened out IVF-28 suitable for planting in moderate and below heavy metal polluted areas.
