摘　　要：以芹菜为试材,在黄河上游地区研究了灌水量、施用氮肥等节水减氮技术对芹菜生长发育及产量的影响,以期为温室芹菜高产、优质、高效栽培及节水灌溉提供科学依据。结果表明:节水减氮对西芹产量的影响达到显著水平;品质方面,总糖含量变化、糖酸化变化受施氮量影响较大,而维生素C含量变化受灌水量影响较为明显,叶绿素含量变化受施氮量影响明显,性能指数则受灌水量变化影响较大。Took celery as the material,the ralationship of reduced nitrogen and water-saving facilities with celery growth and yield were studied in Yellow River region.The results showed that the yield was significant by water and nitrogen saving on celery;quality,the total sugar content influenced by nitrogen,while the vitamin C content was influenced obviously by the amount of irrigation,chlorophyll affected by nitrogen content significantly,the performance index was influenced by changes in irrigation.
