江西信丰县优质脐橙果和叶中稀土元素分布特征研究

Distribution characteristics of REE in quality navel orange fruit and leaf in Xinfeng County, Jiangxi

摘要: 提要：通过1∶5万信丰图组农业地质专题调查，在信丰县4个主要脐橙种植区安西、大塘、西牛和同益等地，采集华脐、朋娜和纽贺尔3个脐橙品种的果、叶样品，采用中子活化法对8个稀土元素（La、Ce、Nd、Sm、Eu、Tb、Yb和Lu）进行分析，研究稀土元素在脐橙果、叶及其立地土壤和母岩中的丰度、分布模式及生物吸收强度等特征，并探讨了稀土元素和脐橙品质的关系。

Abstract: Abstract：On the basis of the 1∶50,000 agro-geological survey of the Xinfeng County Sheet, the neutron activation analysis was used to analyze eight rare earth elements (REE) (La, Ce, Nd, Sm, Eu, Tb, Yb and Lu) in fruit and leaf samples of three navel orange varieties from Anxi, Datang, Xiniu and Tongyi. This paper deals with the abundances, distribution patterns and manikin absorption of REE in navel orange fruit and leaf and their soils and parent rocks and discusses the relationship between REE and the quality of navel orange.
