摘　　要：在田间试验条件下,观察了12种砧木的先锋橙矿质营养元素含量。在观察的11种营养元素中,不同砧木间除 N、Zn、Mo元素含量无显著差异外,其它元素均达显著或极显著差异。其中微量元素的变幅大于大量元素。植株营养状况以宜昌橙类(除 K)、枳类(除 Fe)和桔类砧木植株的养分含量较高,果实含酸量高的砧木植株养分含量偏低。耐碱砧木主要表现在Fe、Mn及 K、Cu元素含量的差异。The experiment was carried out with Xianfeng orange[Citrus sinensis (L. )Osbeck]trees on 12 rootstocks for many years under field conditions. The results showed that the influence of rootstock on P,K.Ca.Mg,Fe,Mn,Cu and B concentrations in the leaf varied significently. The variation ranges of micro-nutrients were greater than those of macro-nutrients. Nutrient concentra-tions in leaves of Yichang papeda, Poncirus trofoliata and mandarin rootstocks are higher than those of others. Rootstocks whose citric acid content in fruit are higher have lower leaf nutrient concentrations. There were differences in Fe,Mn,K and Cu concentrations between rootstocks re-sistant to high pH and normal ones.
