摘　　要：在我国蓝莓主产区大兴安岭利用正交设计方法研究了施硫、控水和施肥3个因素对蓝莓叶片叶绿素荧光特性的影响,拟确定3个因素对蓝莓叶片PSⅡ反应中心功能的影响顺序及最佳水平。结果表明:3个因素互作对蓝莓叶片叶绿素荧光参数影响显著,且不同处理下各荧光参数均明显优于对照。极差分析和偏最小二乘回归结果均显示,3个因素对蓝莓叶片PSⅡ反应中心功能的影响顺序为控水>施硫>施肥。另外,偏最小二乘回归方程中的二次项系数结果揭示3个因素均存在一个最适宜范围,当超过这一范围时会起到相反的作用。综合极差分析结果中各因素最优水平可以确定:施用硫磺70~80 g/m^2,土壤相对含水率约45%~60%,硫酸钾复合肥5~7.5 g/株为最适宜我国大兴安岭地区蓝莓"美登"的农艺措施。The effects of sulphur powder application, water-controlled irrigation and fertilization on chlorophyll fluorescence parameters in leaves of blueberry were investigated using orthogonal design. The main objective was to identify the order of the three factors and the best level on PS Ⅱ reaction center function in leaves of blueberry. The results showed that PS Ⅱ reaction center function in leaves of blueberry was affected by the three factors obviously, and the fluorescence parameters under different treatments were significantly better than that of control. Range analysis and partial least squares regression showed that the effects of the three factors on PS H reaction center function in leaves of blueberry followed the order： water-controlled irrigation〉 application of sulphur powder〉fertilization. In addition, quadratic term coefficient of partial least squares regression equation showed that the three factors had the most suitable range. The opposite effect occurred out of this suitable range. Comprehensive analysis suggested that the best agronomic measures in the Greater khingan mountain area of China are： 70-80 g/m2 of sulfur powder, soil relative water content at 45%-60%, potassium sulphate fertilizer of 5-7.5 g/plant.
