为揭示核桃的光合作用的响应机制，以‘新温185号’核桃为试验品种，比较其在有机肥与化肥配施（NPKM）、单施有机肥（M）、单施化肥（NPK）、农民经验施肥（CK）4种施肥处理下叶片的叶绿素含量、光合特性、叶绿素荧光特性的变化．结果表明：NPKM 处理下核桃叶片的的叶绿素含量分别比 M 处理、NPK 处理、CK 处理提高了3．64％、5．13％、13．39％；与 CK 处理相比，NPKM 处理、M 处理、NPK 处理均能提高核桃叶片的 PSII 原初光能转化效率（Fv／Fm ）和 PSII 反应中心潜在活性（Fv／F0），肥效响应为：NPKM 处理＞M 处理＞NPK 处理＞CK 处理；各处理下核桃叶片的净光合速率日变化均呈“升-降-升-降”的双峰曲线，具有明显的“午休”现象，气孔导度值的日变化与净光合速率相似，光合施肥效应表现为：NPKM 处理＞M 处理＞NPK 处理＞CK 处理．

To reveal the response mechanism of the photosynthetic characteristics,walnuts (cv. Xinwen185)were treated to compare of chlorophyll contents,photosynthesis and chlorophyll fluorescence change under four different fertilization,organic fertilizer combined with chemical fertilizer(NPKM),or-ganic fertilizer (M),chemical fertilizer (NPK),farmers experience fertilization (CK).The results showed that chlorophyll content of walnut treated with NPKM was 3.64%,5.13% and 13.39% higher than that of M,NPK and CK.NPKM,M and NPK treatments improved PSII maximal photochemical efficiency (F v/Fm)and PSII potential liveness (F v/F 0 ),response to fertilizer effect was as:NPKM>M>NPK>CK.The diurnal variation curves of P n of presented the ‘up-down-up-down’double-apex curves,and had a phenom-enon of photosynthetic ‘noon breaking’,the diurnal variation curves of Gs were same as P n ,fertilization effect was as:NPKM>M>NPK>CK.
