滴灌是一种供水系统,它将过滤水(和肥料)直接施于土壤表面或土壤中。它无须喷洒施水,也无须用垄沟或渠道输水,而是使水在低压下以一种预先确定的精确方式散布到土壤中。通过一个广泛分布的管路网把水输送给每棵作物。能把水滴入土壤的出水装置称为滴头。或者采用小直径孔口的方 Drip irrigation is a water supply system that applies filtered water (and fertilizer) directly to the soil surface or into the soil. Instead of spraying water or furrows or channels, it dispenses water into the soil under low pressure in a pre-determined, precise manner. Water is delivered to each crop through a widely distributed network of pipelines. Water can be dropped into the soil water device called the dripper. Or use a small diameter orifice side
