| Abstract: | This article is devoted to discuss the impact of dripper's technical performance parameters (power of discharge x, manufacturing deviation Cv, discharge rate q) on drip irrigation system cost, anti-clcgging and uniformity. It also discusses the relation-ship between drippers flow way/cutlet structure and its technical performance parame-ters and anti-clogging. The author makes a preliminary evaluation on the technical performance parameters of China-made drippers and finally suggests the proper technic-al performance parameters for these drippers and ways to improve the flow way struc-ture. |
