摘　　要：采用叶分析与土壤分析技术,测定辽宁丹东、庄河地区多个越橘果园中4个高丛越橘品种叶片和土壤矿质元素含量,初步确定叶分析标准值适宜范围,为指导科学施肥奠定基础。结果表明,不同越橘园内同一品种叶片常量元素含量差异较小,微量元素差异较大;不同品种叶片矿质元素含量有差异;经改良后土壤中N、K、P和Fe元素含量明显提高,Ca元素含量明显降低,Mg、Cu元素含量变化不明显,pH降低;高丛越橘叶片矿质元素含量标准值适宜范围为:N 1.62%～2.22%,K 0.25%～0.53%,Ca 0.40%～0.90%,Mg 0.12%～0.24%,P 0.09%～0.16%,Zn 14.08～41.00 mg.kg-1,Cu 9.95～16.18 mg.kg-1,Fe 94.49～155.80 mg.kg-1,Mn 89.35～358.70 mg.kg-1。The mineral element contents of leaves of four highbush blueberry cultivars and blueberry plantation soils in Dandong, Zhuanghe in Liaoning Province were examined by technology of leaf and soil analysis. The appropriate range of leaf analysis standard value was made preliminary, which laid the foundation for guiding fertilization scientifically. The results showed that the difference of macronutrients of the same highbush blueberry cultivars among the different parks were less, while the difference of micronutrients were more; the mineral element contents among four highbush blueberry cultivars were different; the contents of N, K, P, Fe in the improved soil were raised obviously, contents of Ca was obviously decreased, contents of Mg and Cu did not change significantly, and pH was decreased; the suitable ranges of mineral elements content standard value of highbush blueberries in Liaoning were： N 1.62%-2.22%, K 0.25%-0.53%, Ca 0.40%-0.90%, Mg 0.12%-0.24%, P 0.09%-0.16%, Zn 14.08-41.00 mg. kg-1, Cu 9.95-16.18 mg. kg1, Fe 94.49-155.80 mg. kg-1, Mn 89.35-358.70 mg-kg-1.
