甘肃灌区既是农作物优质高产区，也是典型的干旱缺水地区。随着灌区种植结构的调整和农村土地流转逐年深入，节水节肥显著、增产增效突出的水肥一体化技术开始在该区推广和应用。但受灌溉制度滞后、施肥体系陈旧，以及可供选择的专用水溶性肥料缺乏等诸多因素制约，技术应用成效受到一定影响，推广速度缓慢。立足不同生态区域特点，结合测土配方技术，围绕高值经济作物和区域优势主导产业，面向不同土地经营主体， 研发并生产速溶性好、肥效显著的专用水溶肥，研究并确定指导性强的水肥一体化技术应用参数，集成提出水肥一体化综合技术体系，并建成可供参考的技术高效应用模式，借助政策引导，强化技术培训，重视示范区建设和带动，是推动水肥一体化技术在甘肃灌区快速应用，实现农业持续高效和生态安全双赢的必由之路。

Gansu irrigated area is not only an area for good quality and high yield crop， but also a typical area of drought and water shortage. With the adjustment of planting structure and rural land transfer， the fertigation technology with saved water and fertilizer significantly， increased crop yield and planting efficiency obviously begun to extend and apply. For irrigation system is lagging behind， fertilizing system is obsolete， and the special water soluble fertilizer which can be chosen is deficient， the application effect of fertigation technology have been affected， the extension speed is slow. Based on the characteristics of different ecological regions， combined with the technology of soil testing and fertilizer recommendation， focused on high economic value crops and regional advantage leading industries， faced to different land management subject， to research and produce special water soluble fertilizer with fast dissolved speed and significant effect， study and make sure the application parameters for fertigation technology， integrate and put forward comprehensive fertigation technology system， set up efficient technology application model that can be used for reference， depend on policy guidance， strengthen technical training and pay attention to the construction of the demonstration zone and its leading effect， that is the only path to promote the feitigation technology application， achieve a win-win situation of sustainable and efficient development for agriculture and ecological environment security in Gansu irrigated area.
