喷灌

Based on hf=λL/DV2/2g,formulain the form of hf= K1·F has beenderived for the hydraulic gradient lines of laterals of subirrigation systems. The formula is also applicable to that of a drip irrigation system. Anotherformula,based on Chezy's V=C RS,in the from of Hf=K2IQ2·F2 has been worked out for the laterals of sprinkler systems.

本文运用管道水动力学原理，对喷灌、滴灌、渗灌系统灌水支管的水力坡降线导出表达的理论公式，讨论其调控的可能途径，为试验研究这类系统的规划设计问题从原理上提供一个分析方法。
