在水资源相对困乏的今天，节水型灌溉技术已经受到广大科技工作者和农民的普遍重视。近几年来，水田节水型灌溉技术发展迅猛，但旱田灌溉发展比较迟缓，笔者根据几年的实际工作、试验，就旱田灌溉做以下初步探讨。一、旱田灌溉的几种主要形式旱作物由于其特性不象永田那样需大 In today’s relatively poor water resources, water-saving irrigation technology has been widespread attention of the majority of scientists and farmers. In recent years, paddy field water-saving irrigation technology is developing rapidly, but the dryland irrigation development is relatively slow, the author based on a few years of actual work, test, on dryland irrigation do the following preliminary discussion. First, several main forms of dryland irrigation Dry crops due to its characteristics are not as large as Nagata
