摘　　要：对纸皮和晚丰2个扁桃品种叶片10种矿质元素(N、P、K、Ca、Mg、B、Zn、Fe、Mn、Cu)进行测定分析,结果表明,2个品种叶片矿质元素年周期变化规律一致,N、P、Zn的质量分数总体呈下降趋势、Mn、Cu、B的质量分数总体呈上升趋势;K、Ca、Fe质量分数前期都呈先升后降的单峰变化趋势,但后期的变化不同;Mg质量分数变化不显著;6月15日-7月1日矿质元素质量分数相对稳定,是扁桃营养诊断的最佳采样时期。扁桃叶片各矿质元素间的相关分析表明,不同元素间存在一定的相关性,其中N、P、Zn间存在极显著正相关关系,Mg和N、P、Zn间存在极显著负相关关系。In the almond＇s vegetative period,ten kinds of mineral elements,including N,P,K,Ca,Mg, B,Zn,Fe, Mn, and Cu, in the leaves of two cultivars named as ＂Zhipi＂ and ＂Wanfeng＂, were deter- mined and analyzed. The results showed that the annual changing trends of mineral elements in the leaves of two almond varieties were similar; the mass fraction of N,P,and Zn mass fraction gradual; the mass fraction of Mn,Cu and B mass fraction increased gradual; the mass fraction of K,Ca and Fe were unimodal trend at the prophase and then different each other; Mg mass fraction changed little; the optimal period for leaf nutrition diagnosis was from 15th June to 1st July; hereinbefore,the rele- vant analysis showed there are correlated between the different elements： the mass fraction of N, P and Zn had significant positive correlation but the mass fraction of Mg and N,P,and Zn exhibited neg- ative relations.
