摘　　要：以牧草地浅埋排根防负压避鼠型地下滴灌管为研究对象,通过大田试验测定不同滴头流量、毛管间距、埋设深度组合下滴灌管的灌水均匀度,结果表明:选用滴头流量为2.0L/h的滴灌管,采用毛管间距60cm、埋设深度20cm的田间布置模式时,灌水均匀度达到0.968,滴灌效果最佳。该产品适用于西部牧区牧草地灌溉,具有较好的推广应用前景。Uniformity of water distribution under the combination of drip irritation pipe with different drippers, drip line spacing and buried depths has been tested, by using underground drip lines of shallow buried anti-negative pressure and rat avoidance type as an objective. The results indicate that best performance can be reached when dripper flow of 2.0 L/h and drip line spacing of 60cm are adopted, as the uniformity of drip irrigation pipe can reach 0.968. The product may suit to grazing land irrigation and has a future for widely application and extension.
