中文摘要：
间接地下滴灌是一种高效的节水灌溉方式,滴头流量是灌溉设计的重要参数。通过室内试验,研究不同滴头下不同灌水历时间接地下滴灌湿润体特征值的变化规律,结果表明：间接地下滴灌下土壤湿润体为近似椭圆体,湿润体的水平、垂直向下和向上湿润锋均与时间有显著的幂函数关系,且相关性较好;灌水历时相同时湿润体体积随滴头流量增大而增大,灌水量相同时湿润体体积随滴头流量增大而减小。
英文摘要：
Dripper discharge is one of the important parameters. The article was conducted to investigate the effect of different dripper discharge on the characteristic value of soil wetted volume by indoor experiment. The results show that wetting body is the approximate ellipsoid, horizontal and vertical advance distance of soil wetted front conformed to power function of infiltration time under indirect subsurface drip irrigation and the calculated value is better. Wet body volume increases with increasing dripper discharge in the same irrigation time, the wet body volume becomes smaller with the increase of dripper discharge with the same irrigation water.
