| 摘 要： | 在陕北黄土高原具隔水小区的日光温室内，设计完全随机区组试验，研究了不同水肥组合对结瓜期黄瓜叶片生长和产量的影响。结果表明，在结瓜期，所有处理黄瓜叶面积逐渐增加，而叶片扩展速率、叶片组织含水率、叶片中游离脯氨酸（PRO）和丙二醛（MDA）含量、黄瓜产量和水分利用效率（WUE）均先增加后降低；当土壤含水率一致时，高肥处理（N：600 kg/hm2，P2O5：420 kg/hm2）叶面积、叶片扩展速率、产量和WUE显著高于低肥处理（N：420 kg/hm2，P2O5：294 kg/hm2）；低肥处理产量随土壤含水率增加而增加，高肥处理随土壤含水率增加先增加后降低，WUE随土壤含水率增加而降低。中水高肥处理（WmFh）的叶片净光合速率（Pn）和蒸腾速率（Tr）日变化均高于其他处理。表明，中水高肥处理（田间持水率＞75%～90%，施用N：600 kg/hm2，P2O5：420 kg/hm2）黄瓜在结瓜期叶片生长健壮、光合作用强、产量较高，节约了水资源。 |

| Abstract: | Physiological characteristics of cucumber leaves and yield under different watering and fertilizer coupling treatments were determined with completely random experiment setup in greenhouse on Loess Plateau. The results showed that in all treatments leaf area became bigger,and those parameters such as leaf expansion speed(LES) ,leaf water level,the amount of free proline(PRO) ,malondialdehyde(MDA) ,yield and water use efficiency(WUE) were increased initially and then decreased at the fruit-bearing stage.
