| 摘 要： | 文章对生长于辽宁省鞍山地区的南果梨的稀土元素的地球化学特征进行了研究。结果表明,南果梨生长环境各部分稀土元素总含量分布为:土壤>树叶>树枝>果实;稀土元素经过生物吸收后主要富集于叶部,进入果实中的稀土元素含量大会影响果实品质;增加土壤有机质是发挥稀土肥效和改善果实品质的有效手段。

| Abstract: | The geochemical characteristics of rare earth element(REEs) in Nanguo pear in Anshan,Liaoning Province,were studied.The results showed that the sequence of REEs distribution is soil >leaf>branch>fruit.REEs mainly riched in leaf after biologic adsorption,and influenced on the quality of Nanguo pear.Addition of organic matter facilitatded the quality improvement of Nanguo pear and to function the fertilizer effect on REEs. |
