摘　　要：水资源短缺和肥料利用率低是我国农业发展面临的突出问题。水肥一体化灌溉是将灌溉与施肥融为一体的灌溉模式,可根据作物不同生育时期需水需肥规律,将水分和养分定时定量按比例精准提供到作物根部。综述了国内外水肥一体化灌溉及相关技术研究进展、西瓜全生育期水肥需求规律和水肥一体化灌溉模式对西瓜生长发育、产量及品质的影响,分析了水肥一体化灌溉面临的问题并提出相关解决方案。深入研究水肥一体化灌溉理论、优化灌溉设备和改变传统灌溉施肥方式,可为指导西瓜节水、节肥、优质和高产提供理论依据。Water shortage and low utilization rate of fertilizer are outstanding problems facing China's agricultural development.Integrated irrigation of water and fertilizer is an irrigation mode that integrates irrigation and fertilizer application into one,which can provide water and nutrients to roots of crops accurately in proportion and at regular intervals according to water and fertilizer demand rules of crops in different fertility periods.Research progress of integrated irrigation and related technologies of water and fertilizer at home and abroad,law of water and fertilizer demand during entire growth period of watermelon,and impact of integrated irrigation mode of water and fertilizer on growth,development,yield,and quality of watermelon,were summarized.Problems faced by integrated irrigation of water and fertilizer were analyzed,and relevant solutions were proposed.Deeply studying theory of integrated irrigation of water and fertilizer,optimizing irrigation equipment,and changing traditional irrigation and fertilization methods could provide theoretical basis for guiding water-saving,fertilizer saving,high-quality,and high-yield watermelon.
