摘　　要：对三峡库区重庆市忠县加工甜橙基地17个甜橙园哈姆林甜橙叶片的氮、磷、钾、钙、镁、锰、铁、铜和锌等9种矿质营养元素进行了分析测定。结果表明,哈姆林甜橙叶片中氮的含量偏高,平均值为2.89%;磷、钾、钙、铁和铜的含量处于适量范围,平均值分别为0.15%、1.41%、4.08%、83.34mg·kg-1和6.82mg·kg-1;而微量元素镁、锰和锌严重缺乏,平均值分别为0.23%、20.24mg·kg-1和14.08mg·kg-1。进一步相关性分析表明,氮与锰的正相关系数达到极显著水平;钙与氮、磷、铜和锌呈正相关,而与其他4种元素呈显著负相关。Contents of N, P, K, Ca, Mg, Fe, Mn, Cu and Zn in leaves from 17 Hamlin sweet or ange orchards in Zhongxian county were analyzed. Results showed that the content of N was averaged at 2.89±0, 28%, which was high, and that the contents of P, K, Ca, Cu and Fe were in optimum range as showed by the average contents of 0.15%±0. 01%, 1.41%±0. 29%, 4.08%± 0.47%, 83.34 mg· kg^-1±16. 58 mg·kg^-1, 6. 82 mg· kg^-1±1. 72 mg·kg^-1, respectively. However, Mg, Mn and Zn contents were in serious deficient. Correlation analysis indicated that N was in significant positive correlation with Mn. Ca was in positive correlation with P, but in significant negative correlation with other 6 elements.
