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。

Abstract: Contents of N,P,K,Ca,Mg,Fe,Mn,Cu and Zn in leaves from 17 Hamlin sweet orange 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.
