垄作沟灌技术具有显著的节水增产作用，但在春小麦种植中应用尚缺乏参数设计方面的理论支撑。本研究采用粉砂质粘壤土与粘土两种典型土壤实测水分运动参数和 HYDRUS 软件，模拟了梯形灌水沟不同垄宽情况下的土壤水分运动和停水后水分再分布，研究了不同灌水量时湿润锋推进过程和水分再分布后的湿润体变化，分析了设计灌水定额下适宜作物生长湿润体范围，提出了粉砂质粘壤土和粘土宜采用的合理垄宽为20～50 cm 和20～35 cm ，这一结果为干旱区春小麦垄作沟灌技术推广提供了技术支撑。

Ridge tillage with furrow irrigation technology possess a significant role of water saving and increasing yield ,but lack the theory support for application in spring wheat planting .In this research ,adopted two typical soils as silt sandy clay loam and clay ,measured the soil water moving parameters and using the HYDRUS software ,have simulat-ed the soil water movement and water redistribute after stop water supply under the different ridge width of trapezoidal fur -row ;have researched the advancing process of wetting front and wetting body change with water redistribute under differ -ent irrigation volume ,have analyzed the range of wetting body for suitable plant growth under the design irrigation quota , also have put forward the rational width as 20 to 50 cm and 20 to 35 cm for the silt sandy clay loam and clay soil respec-tively .This result can be provided the technical support for extending the ridge tillage with furrow irrigation technology of spring wheat in arid areas .
