摘　　要：通过对华北平原地区旱作大田作物田间灌溉方式的调查研究,发现传统的地面灌水方法存在着蒸发量大、深层渗漏多,水分利用效率低,田间灌水均匀度差等问题。为了提高旱作大田的水分利用效率,提出一种新的灌溉新技术——旱作膜袋灌,实现适时适量精细控制灌溉。通过试验研究,膜袋灌能够较好地提高大田作物的田间水分利用效率,避免沟灌、畦灌等传统地面灌水方法存在的棵间蒸发和深层渗漏,同时也能够解决滴灌、微润灌、喷灌等灌水方法易堵塞、系统复杂、田间工程量大和经济成本高等问题,对现代的高效节水农业具有重要的现实意义。Through the investigation and study on the field irrigation methods of dryland field crop in North China Plain, it was found that the traditional surface irrigation methods had the issues of strong evaporation, much deep infiltration, low water use efficiency, poor uniformity of field irrigation and so on.A new irrigation technology -dryland film-bag irrigation was put forward in order to im-prove water use efficiency in dryland field, which could achieve timely moderate fine control irriga-tion.It can improve crop water use efficiency, avoid the soil evaporation and deep leakage caused by furrow irrigation, furrow irrigation and other traditional ground irrigation methods through the experi-mental study on the dryland film-bag irrigation.At the same time, it can solve the problems as easy jam, complex system, huge amount of work, and high economic cost caused by micro irrigation, drip irrigation, sprinkler irrigation, which has important practical significance for modern efficient water-saving agriculture.
