摘　　要：本试验以尤力克柠檬为接穗,研究沃尔卡默、卡里佐枳橙、枳、红橘、香橙、斯文格枳柚6种砧木对尤力克柠檬幼树生长及叶片矿质元素含量年变化的影响。结果表明,不同砧木对尤力克柠檬的树体生长及成花特性有明显的影响;总体来看,以卡里佐枳橙、斯文格枳柚和沃尔卡默处理的生长势较旺盛;香橙和沃尔卡默处理表现植株矮化,但这两个处理的春花花量极显著地高于其它处理,红桔和枳处理的春花和秋花量均较少。不同砧木处理不影响尤力克叶片N、P、K、Mg和Mn含量年变化动态的特征,而明显影响Ca、Fe和Zn含量的年动态特征;在各不同时期,不同处理对叶片各矿质营养含量有较明显的影响。试验结果为科学评价各柠檬砧木的吸肥特性及合理施肥提供参考依据。The effects of six different rootstocks on the mineral nutrition changes and growth of Eu-reka lemon leaves were investigated in this paper. The results showed that there were notable influence on the vegetative growth and flowering property of different treatments. Generally speaking, three kinds of treatments Carrizo citrange, Swingle citrumelo and Volkamer grew more vigorously than others. The plant became more dwarfling when Junos and Volkamer were used as rootstock of Eureka, whereas the number of spring flower of these two rootstocks re- markably higher than other treatments. Both Red tang-erine and Trifoliate had lower flower number than other four treatments in season of spring and autumn. The rootstocks did not influence the annual changes of N, P, K, Mg and Mn in leaves, but notably influenced the annu changes of Ca, Fe and Zn in leaves. During different periods, the rootstocks remarkably influenced the contents of mineral nutrients in leaves. These consequences would provide a foundation for proper evaluation of fertilizer absorption of different rootstock and rational fertiliza- tion.
