摘　　要：传统的灌水、施肥方式不仅水肥利用率低、人工和成本增大,而且污染农田环境。水肥耦合技术通过对灌水与施肥合理的配比达到提高水肥利用效率、产量、品质,以降低生产成本的目的。综述了水肥耦合调控对南瓜生长发育过程、光合作用、产量及品质的影响。结果表明,合理的水肥调控能显著促进南瓜生长发育及光合作用,对干物质积累有积极作用,可提高南瓜产量与品质。最后对水肥耦合技术在农业生产中的推广与应用进行了展望。Traditional irrigation and fertilization methods not only have low water and fertilizer utilization rates,waste labor and costs,but also pollute agricultural environment.Coupling technology of water and fertilizer achieves goal of improving water and fertilizer utilization efficiency,yield,quality,and reducing production costs through a reasonable ratio of irrigation and fertilization.Effects of water fertilizer coupling regulation on growth and development process,photosynthesis,yield,and quality of pumpkin was mainly reviewed.Results showed that reasonable water and fertilizer regulation could significantly promote growth,development,and photosynthesis of pumpkin,had a positive effect on dry matter accumulation,and improve yield and quality of pumpkin.Finally,promotion and application of water and fertilizer coupling technology in agricultural production were prospected.
