The experimental results show that there is an essential difference between the uniformity of dripper discharge along the drip line and the uniformity of soil moisture in field in terms of the design of linear source drip irrigation.

线源滴灌设计中，滴灌管出流均匀性与土壤湿润均匀性有本质不同，前者仅仅是后者必要的基础，但是要保证线源滴灌土壤湿润均匀性，还需要考虑滴头间距、滴头流量、滴水量和土壤质地的差别。

Irrigating water supply had more effects on the moisture uniformity than dripper discharge in soil along the vertical drip irrigation pipe direction and intersection of wetted front.
