1 地面浸润灌溉 日本推出。在灌溉时 ,土壤借助毛细管的吸力自动从含水系统散发器中吸水 ,当含水量达到饱和度时 ,吸力变小 ,系统散发器便自动停止供水。由于系统散发器的流量仅为 0 .0 1g/秒 ,盐分无法以溶液状态存在 ,只能聚集于土壤表面 ,使土壤内的湿润区变为脱盐的淡水
1 ground infiltration irrigation launched in Japan. During irrigation, the soil absorbs water automatically from the aqueous system dispenser by capillary suction, and as the water content reaches saturation, the suction becomes smaller and the system dispenser automatically stops supplying water. Since the system dispenser has a flow rate of just 0,01 g / s, salt can not exist in solution and can only concentrate on the surface of the soil, changing the moist area within the soil to desalinated fresh water
