摘　　要：柑橘在我国农业生产中占有重要的地位,本文综述了必需矿质营养元素对柑橘树体营养、果实产量及品质的影响。大量营养元素(氮、磷、钾)施用普遍且效果较明显,中量营养元素(钙、镁、硫)的研究应用还存在着一定的局限性,而微量元素(硼、锌、铁、锰、钼)的施用效果则存在较大的变异性。此外,还介绍了柑橘适宜的土壤及植株元素含量范围。最后,提出了今后柑橘矿质营养研究中应着重解决不同柑橘品种各自的元素适宜含量、柑橘营养机理、养分高效利用的砧穗组合及平衡施肥等几方面的问题。Citrus production is very important in China＇s agriculture.This review summarizes the influences of essential mineral nutrients on nutrition,fruit yield and quality of citrus.Macro elements（N,P and K） are applied widespread and their effects on fruit yield and quality are obvious.To the middle elements（Ca,Mg and S）,there are still some limitations at the aspects of study and application.The effects of trace elements（B,Zn,Fe,Mn and Mo） on citrus still have a large variability.In addition,we give appropriate ranges of nutrient concentrations in citrus leaves as well as in soil.Furthermore,several problems on mineral nutrition of citrus research,including the determination of suitable concentrations of essential elements in citrus cultivars,the mechanism of citrus nutrition,the selection of rootstock-scion combination for efficient utilization of nutrients and balanced fertilization,should be focused,and this may provide the reference to implement high yield and quality fertilization of citrus.
