【目的】探究黄金梨树氮吸收对水氮耦合的响应规律。【方法】设定灌水下限和施氮量2个因素，每个因素设定3个水平，即灌水下限：高水（HW：75%Fc）、中水（MW：65%Fc）和低水（LW：55%Fc）（Fc：田间持水率（体积含水率））；施氮量：高氮（HF：486 kg/hm2）、中氮（MF：324 kg/hm2）、低氮（LF：162 kg/hm2），正交设定9个试验处理，对照处理为园区常规管理（CK）。测定了果实膨大期和成熟期梨树春梢、叶片和果实全氮量。【结果】果实膨大期，中水中肥（MWMF）处理梨树春梢和叶片全氮量最高，较CK分别提高了26.20%和8.66%；灌水下限对春梢全氮量影响差异不显著，施氮量和耦合作用对春梢全氮量提高差异显著；灌水下限、施氮量及耦合作用对叶片全氮量提升差异不显著。成...
