以明沟排水为对照，论述了内陆干旱重盐碱区暗管排水在排水排盐、控制地下水位、提高土壤脱盐效果及提高作物产量等方面的优越性。
Subsurface pipe drainage in drought-prone region is superior to surface drainage in draining off water and salt, controlling ground water-level, and increasing crop output, etc.
水分的脱盐效率随淋洗水量和入渗水矿化度的增加而减小，与土壤初始含水量无关。
The desalting efficiency of saline water decreased with increasing amount of leaching water and the concentration of saline water, but was independent of initial soil water content.
土壤初始含水量对初期水分脱盐效率有影响，但对后期水分脱盐效率影响不大。
Initial water content also had effect upon water desalting efficient but confined to initial stage of infiltration.
