摘要
对比枣树滴灌自动化系统建成前后的滴灌系统工作压力和滴头流量,结果发现：滴灌自动化系统建成后支管压力和滴头流量偏差明显减小,滴灌管的滴头平均流量（qv）增大,滴灌系统的均匀度提高了4.98%~11.0%,提高了滴灌系统的灌水均匀度和水分利用效率,为解决灌溉水深层渗漏,灌区产生次生盐渍化的问题提供了解决方案.
Working pressure and flow rate were measured before and after the completion of jujube automatic drip irrigation system, The results show that the pressure of branch pipes and the flow deviation of dripper discharge decrease obviously after the completion of the automation system, while the average flow rate （qv） of drippers on drip line is increasing, the uni-formity of drip irrigation system increases by 4. 98% -11 .0%,improving the irrigation uniformity and water use efficiency of drip irrigation system, which provides technical support to solve the problems of irrigation water deep seepage and secondary salinization in irrigation area.
