本成果历时20年以上，从过程机理研究入手，通过长期系统田间试验：发现控制特征点土壤基质势可有效控制作物根区水分状况，建立了20多种作物生长、耗水与该点土壤基质势的关系，并提出了微灌农田水分管理方法；在干旱区控制特征点土壤基质势在特定阈值时，可很好地实现盐分淋洗，提出了水盐调控精确施肥灌溉方法;建立了“分户”、“分组”和“统一”3种适合不同类型用户的灌溉模式；创新了过滤、注肥和控制系统及土壤墒情监测装置等关键设备；研发了“硬件”和“软件”集成为一体的“傻瓜化”成套技术产品。

该技术已经成为国际上自成体系的技术。具有简便易操作、节水增产效果显著等特点。应用表明，可节水35～63%，增产16～50%，每年节省生产费用110～190元/亩。

The research has lasted for more than 20 years. Starting from the process of mechanism research, through the long-term systematic field trials:  it was found that controlling the soil matric potential at characteristic point can effectively control water status in crop root zone, and established the relationships between the soil matric potential and the growth, water consumption of more than 20 kinds of crops, and proposed water management method for drip irrigation farmland.  it was found in arid area when the soil matric potential at characteristic point was controlled at a certain threshold, the salt leaching can be well achieved, and put forward the method of water and salt regulation and precision fertigation for drip irrigation. the "household", "group" and "unified" irrigation models for three different types of users were established; filter system, fertilizer injector system and control systems, soil moisture monitoring devices and other key equipment were innovated; sets of "hardware" and "software" integrated products and technology were developed.
