建立了小管出流环沟灌溉土壤水运动的数学模型和环沟内水流推进模型，并用数值法求解。应用该模型可以确定小管出流环沟灌溉的技术参数。
The mathematical model of soil water movement in the canal outflow gully and the water flow propulsion model in the gully have been established and solved numerically. The model can be used to determine the technical parameters of outflow gully irrigation.
