摘　　要：为了评价Cd污染地区西瓜种植的安全性,通过对Cd污染地区的西瓜品种筛选和大棚长季节栽培试验研究了58个西瓜品种对Cd积累的差异,以期筛选出低Cd积累的西瓜品种。研究结果表明,在土壤Cd含量低于0.973 mg·kg^(-1)时,西瓜果实Cd含量均低于国家现行标准GB 2762-2012,其中‘黑媚娘’的Cd含量最低。西瓜长季节栽培时果实中Cd含量随着采收批次的增加呈增加趋势,‘橙玉’最后一批果实中Cd含量为28μg·kg-1,因此在中度Cd污染地区西瓜生产是安全的,建议推广种植‘黑媚娘’‘超级京欣’‘金鑫’和‘金福’等低Cd积累西瓜品种。To assess the security of watermelon cultivation in Cd contaminated soil effectively and efficiently,the variation of Cd content in 58 watermelon genotype materials and the effect of Cd concentration in Cd contaminated farmland soil on Cd content in watermelons were investigated through field experiments and long season cultivation experiment in order to screenout Cd-pollution-safe watermelon cultivars. It was found that the content of Cd in watermelon fruits from the field with the soil Cd content below 0.973 mg · kg^（-1） is lower than the current national standard GB 2762-2012, the Cd content of‘Heimeiniang＇is the lowest. The Cd content in watermelon fruit from long season cultivation with the increase of recovery batches showed a trend of increase, the Cd content in the last harvested fruits of ＇Chengyu＇ is 28 μg · kg-1.Watermelon production in moderate Cd pollution area is safe, watermelon varieties‘Heimeiniang＇,‘Chaojijingxin＇,‘Jin xin＇and‘Jin Fu＇are recommended in planting low accumulation.
