中文摘要	节水灌溉是干旱、半干旱和半湿润地区发展农业生产提高粮食产量的重要措施，经济有效的灌溉管理技术可起到既节水又增产的作用。本项技术是在总结国内外研究成果的基础上，反水分－土壤－作物－大气作为一个整体，利用物质能量守衡原理建立水量平衡方程。依据测定土壤的物理参数（土壤容重、田间持水量、测萎系数、初始土壤含水量）再结合气象预测温度、降雨资料，用先进的计算方法，获得灌溉时间和灌溉定位，从而确定合理的灌溉制度。应用实践表明此项技术具有很好的增产和节水作用。
英文摘要	Water-saving irrigation is important to develop agriculture and increase yields in the arid, semi-arid and semi-humid areas. An economical and effective irrigation management technique can save water and increase yields as well. This technique, based on a summation of researches both in China and abroad, takes moisture content, soil, plant and atmosphere as a integral part of the whole, sets up and water-balance equation by means of the law of conservation of matters energy. The equation is: W_(soil) = F_(rainfall) + Q_(irrigation) + W_(origination) - W_(runoff) - W_(wither) - W_(penetrate) - nETc Such physical parameters as soil unit weight, field capacity, withering parameter, original soil’s water content and etc. were surveyed. The meteorological data as temperature and rainfall from meteorological observation and forecast were obtained. The advanced method is applied to calculate crop’s transpiration. According to the relation between soil’s water content and crop’s transpiration, the irrigation time and amount are obtained. Thereby a proper irrigation system is determined. The application shows that this technique has the very good function to increased corn yield and save water.
