摘　　要： 以纽荷尔脐橙 / 3种不同中间砧 /枳为试材进行田间试验研究不同中间砧对基砧根系矿质营养含量的影响。结果表明 ,3种中间砧对基砧根系P、K、Mg和Fe含量年变化趋势的基本特征无明显影响 ;而对叶片N、Ca、Mn和Zn含量的年变化趋势特征有明显影响。在年周期的不同时期里 ,基砧根系K、Ca和Mn含量在 3种不同中间砧之间存在显著或极显著差异 ;而其余矿质营养含量在 3种不同中间砧之间只在部分时期里存在显著或极显著差异 ;而在各矿质营养含量存在显著或极显著差异的不同时期间 ,该矿质营养含量在 Study on the effects of different kinds of interstock on the annual changes in the contents of 8 kinds of mineral nutrient in root by doing field experiment with the materials 'Newhall navel orange/3 kinds of interstock/trifoliate'. The results indicted the following. 3 kinds of interstock had no obvious effects on the tendencies of the annual changes in the contents of 4 kinds of mineral nutrient such as P and K and Mg and Fe in root, and had noted effects on annual changes in the contents of N and Ca and Mn and Zn in root. The contents of K and Ca and Mn in root among 3 kinds of interstock had remarkable difference during every period of the annum. The contents of the other kinds of mineral nutrient among 3 kinds of interstock had remarkable difference during some periods of the annum. Meanwhile, among the periods when the contents of each mineral nutrient had significant difference, the tendency of the relative difference of the kind of mineral nutrient in one period didn't always have the same turn as the others.
