Drip irrigation is the most effective water-saving irrigation method in arid and water-scarce areas, and its water utilization rate can reach 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to more than double the fertilizer efficiency. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses. It can also be used for irrigation of field crops in dry and water-deficient areas. The disadvantage is that the dripper is easy to scale and clog, so the water source should be strictly filtered.
