摘要
自流灌区的自然低水头微灌技术,既节水又节能,但因自然水头低导致微灌系统灌溉均匀性差。由此,基于新提出的蓄流灌溉技术理论和灌溉模式,以蓄流灌溉关键技术设备蓄流灌水器结构、工作原理及其特有灌溉用水运行方式进行分析,对其水头损失计算、灌溉均匀控制原理与解决的技术途径、蓄流灌溉田间布设与灌溉均匀管理控制等诸方面进行了研究。技术研究和试验表明,蓄流灌溉方式是解决和处理自然低水头微灌系统灌溉均匀性差的一种有效技术方法,为自流灌区自然低水头条件下微灌系统灌溉均匀性问题解决提供了新思路新途径。
The technology of natural low-head irrigation has the advantage of water saving and energy-saving, but its uniformity is poor for the low pressure. Therefore, based on the theory of storage irrigation mode, the structure and operating principium of the douche, the characteristical operating mode of the system were analyzed in this paper. In addition, the authors studied the calculation method of pressure loss, the principium and technical method of irrigation uniformity control, the lines design in the field, and the irrigation uniformity management. The result showed that storage irrigation is an effective method to solve the problem of poor irrigation equality in the natural low-head micro-irrigation systems.
