中文摘要：
南丰蜜桔是原产江西南丰地区的重要水果品种,但是对于该品种的稀土元素含量的研究还没有见到报道。借助ICP-MS/ICP-AES方法对南丰产的南丰蜜桔及其种植土壤中的稀土元素进行了全面分析,目的是研究南丰蜜桔中稀土元素的含量以及与土壤中稀土元素含量的关系。结果显示：南丰蜜桔仅仅能够测到10种稀土元素的存在,它们是La,Ce,Pr,Nd,Sm,Eu,Gd,Dy,Ho和Yb,它们的含量在0.63-0.01ng·g^-1之间。种植南丰蜜桔的土壤中上述十种稀土元素含量在29.36-0.07μg·g^-1之间,含量最多的三种元素是Ce,La和Nd,含量分别是29.36,16.92和8.62μg·g^-1。南丰蜜桔中稀土元素含量与土壤中的稀土含量基本上成正相关：土壤中稀土元素含量越多,其在果实中的含量也越高。所以如果要通过稀土元素增加产量、提高品质,土施稀土元素效果也会非常明显。
英文摘要：
Nanfeng orange is a famous fruit in the world, but the content of rare earth in the fruit and its relation to the content in soil were little studied. The present paper studied the contents of rare earth in Nanfeng orange fruit and the effects of soil planting Nanfeng orange on the contents of rare earth in Nanfeng orange fruit by ICP-MS/ICP-AES in order to find the relation of rare earth content in the soil to that in Nanfeng orange fruit. The results showed that ten kinds of rare earths were detected, namely La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho and Yb, whose contents range from 0. 63 to 0. 01 ng·g^-1, while the contents of the ten elements range from 29.36 to 0. 07μg·g^-1 in the soil. All data showed that the content of rare earth in fruits is right relative to that in soil. So the authors can conclude that fertilizing with rare earth should he the best way to enhance the content of rare earth in Nanfeng orange fruits.
