摘要
小管出流灌溉系统的设计方法步骤与滴灌系统大致相同。但由于小管灌水器的出流量比滴头大得多，系统设计的许多问题又具有特殊性。本文论述了设计均匀度的确定，适宜毛管直径和长度的确定，以及田间管网水力学计算等问题。［关键词］
it is nearly same that the design metheds and steps of the irrigation system with small--pipeoutflow are nearly the same as thos of the drip irrigation system. Because the flow rate of small-pipeemitter is much bigger than the flow rate of drip emitter, there are a lot of problems in systemdesigning.This paper has discused some problems on determining design uniformity, suitable lateraldiameter and the length and hydraulic calculation of field pipe netword.
