宁夏南部窖水区移动式滴灌应用技术

Practical Techniques of Mobile Dripping Irrigation in Water Collecting Cellar Area

着重研究了全移动窑窖滴灌技术的设计、设备配套与选型。确定了合理的水泵型号 ,适合窑窖滴灌的灌水器、过滤器。在管网布局上突出了窑窖滴灌的灵活性与适应性。提出电动加压移动滴灌模式为 1套移动设备控制 4眼窖 ,滴灌 8亩地 ,简称“1·4·8”模式 ;手动加压移动滴灌为 1套移动设备控制 2眼窖 ,滴灌 4亩地 ,简称“1·2·4”模式。

Design, equipment completion and type selection of mobile dripping irrigation technique by water collecting cellar are emphatically studied. Reasonable pump model, suitable dripping instruments and filter of water cellar dripping irrigation have been determined. Much attention has been paid on the suitability and flexibility of the facility in tube distribution. The “1·4·8” pattern, that is one set of the mobile equipment controls four water storage cellars and irrigates 8 mu farmlands, is raised as practical electricity running mobile pressure dripping irrigation model. As to the handrunning pressure dripping irrigation, the model is “1·2·4”, that is one set of equipment, 2 water cellars, and 4 mu irrigated farmland.
