In the design of drip irrigation system, reasonable dripper discharge should be chosen and irrigation water should be supplied in order to make soil reach the designed moisture uniformity; the moisture uniformity of soil along the drip irrigation pipe should be controlled mainly.

文中提出了应用于工程设计中的滴头流量设计模式应满足的要求。在滴灌系统设计中，要使土壤达到设计的湿润均匀度就应选择合理的滴头流量，并设计出合理的灌水量，而且应主要控制沿滴灌管方向的土壤湿润均匀性。

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.

灌水量对垂直滴灌管方向和湿润锋交汇处土壤水分均匀性的影响比滴头流量对其影响大。

The results indicated that irrigation water supply and dripper discharge had extreme effects on the moisture uniformity in soil along the drip irrigation pipe direction for line source drip irrigation, the soil moisture uniformity would be raised with the increase of irrigation quantity and dripper discharge.

试验表明：线源滴灌下，灌水量、滴头流量、滴头间距对沿滴灌管方向的土壤湿润区均匀性影响最大，随着滴头流量或灌水量的增加以及滴头间距的减小，湿润均匀性提高。
