滴灌是一种先进的灌水技术。滴灌系统通常由水泵、流量和压力调节闸阀、肥料混合罐、过滤器、干管(输水管)、支管(引水管)、毛管(灌水管)和滴头组成(见下图)。它采用低压管道输水,通过放置在作物根部附近的滴头,将水一滴一滴地送到作物根系周围的土壤里。滴灌具有增产、省水、省工、省地、对地形适 Drip irrigation is an advanced irrigation technology. Drip irrigation systems are usually composed of pumps, flow and pressure regulators, fertilizer mix tanks, filters, mains (pipes), branch pipes (water pipes), capillary tubes (drip pipes) and drippers (see picture below). It uses low-pressure pipelines to deliver water drop by drop to the soil around the root system of the crop through drippers placed near the root of the crop. Drip irrigation with stimulation, water conservation, labor, provincial, suitable for topography
