Drip irrigation does not damage the soil structure, and the water, fertilizer, air and heat inside the soil are always kept in a good condition suitable for crop growth, with small evaporation loss, no surface runoff and almost no deep seepage, so it is a water-saving irrigation method. The main feature of drip irrigation is small irrigation volume, and the flow rate of the irrigation device is 2-12 liters per hour, so the irrigation duration is relatively long, the irrigation cycle is short, and small water irrigation can be achieved. At the same time, the working pressure required by drip irrigation is low, the irrigation volume can be accurately controlled, the invalid inter-plant evaporation can be reduced, water waste can be avoided, drip irrigation can be automatically managed, and the effect is good.
