摘要
通过对大红甜橙不同程度缺铁失绿发病植株铁素含量与其它矿质元素含量的关系、正常含铁植株与其它矿质元素相关性的统计分析，结果表明：中度缺铁失绿植株叶片中铁素含量与锌素含量呈极显著正相关（相关系数ｒ＝０．８７６），与钾素含量呈显著正相关；轻度缺铁失绿树叶片中铁素含量与钾、锌元素含量呈显著正相关；正常含铁植株叶片中铁素含量与钙、硼营养元素含量呈极显著正相关（相关系数ｒ值分别为０．８１４、０．８６４），与钾、锌营养元素含量呈显著正相关。
The correlation between iron element and other minerals were analysed statistieally in different iron chlorosis and normal Dahong sweet orange trees. The results obtained were summarized as follows: In leaves of middle degree Iron chlorosis. Fe had very significantly positive correlation with Zn (r=0.876) and significantly correlated with K; in leaves of light degree Iron chlorsis, Fe and K、 Zn were also sighficantly correlated; in leaves of normal iron Dahong sweet orange trees, Fe and K、Zn were very significantly positive correlations (r=0.814、0.864).
