Subsurface drip irrigation (SDI) skills and characteristics SDI is a method of slowly delivering water or a water-fertilizer mixture into the soil of the crop root zone through water emitters on buried capillaries, and then using capillary action or gravity to disperse the water to the root layer for absorption and use by the crop. Compared with other irrigation methods, SDI has significant advantages: it significantly saves water, has a high fertilizer utilization rate, and can optimize product quality and increase yield. At the same time, SDI technology can operate with small flow and low head, saving operating costs.
