摘　　要：根据半干旱低山丘陵地区的地理条件和水资源特点,以低压管灌和二次加压喷灌等工程节水技术为依托,配合农业节水措施和管理节水措施,对水土资源进行逐级开发,高效利用。根据示范区应用效果观测,技术应用后节水26.35%,扩大单井控制灌溉面积3.17倍,每公顷增加经济效益4 692.9元。According to the geographical conditions and water resources availability of semiarid hilly area, the water and soil resources were cascade-developed and utilized in high efficiency in the area through using water-saving techniques such as low pressure pipeline irrigation technique, sprinkling irrigation technique with secondary pressurization, and agricultural water saving strategies and management. The experimental results showed that the irrigation water application decreased 26.35%, the irrigated area enlarged 2. 17 times, and the benefit increased 4692. 9 yuan per hectare.
