为了研究干旱区全膜垄作沟播和喷灌技术结合的适应性，开展全膜垄作沟播条件下灌水量与向日葵根系变化特征、干物质积累、土壤含水率动态变化和产量效应及节水率等几个方面关系的试验研究，并与全膜平铺喷灌进行了比较。结果表明：全膜垄作沟播喷灌技术可抑制土壤水分无效蒸发，提高灌溉水分的利用效率，有较高的增产和节水效率，在降水稀少的干旱区是非常实用的。

The helianthus is the main cash crop in arid inland areas of Hexi, ridge tillage and ditch seeding is mainly rain-fed agriculture cultivation methods in semi-arid region. The sprinkler irrigation is one of the main efficient methods. The paper through the ridge tillage and ditch seeding under all-film farming techniques and sprinkler irrigation technology combination, studied the changing characteristics of roots, dry matter accumulation, soil moisture, productivity and water saving rate. Results show that the ridge tillage and ditch seeding under all-film farming can inhibit the soil water evaporation, improve irrigation water use efficiency and have higher yield and water-saving efficiency. It is promoted the binding mode of new farming technology and efficient irrigation technology.
