Drip irrigation uses plastic tubing to deliver water to the root of the crop through a hole or dripper on a capillary tube approximately 10 mm in diameter for local irrigation. It is the most effective water-saving irrigation method in the current drought-stricken areas, and its water utilization rate can reach 95%. Compared with sprinkler irrigation, drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to increase fertilizer efficiency by more than one time. It can be applied to fruit trees, vegetables, cash crops and greenhouse irrigation, and can also be used for irrigation of field crops in dry and water-deficient areas. The shortcoming is that the dripper is easy to scale and block, so the water source should be strictly filtered. At present, domestically produced equipment has basically passed, and areas with conditions should actively develop drip irrigation.

The degree of fixation of the pipe can be divided into three types: fixed type, semi-fixed type and mobile type. For fixed drip irrigation, the location of the pipes and dripper at each stage is fixed during the irrigation season. The advantage is that the operation is simple, labor-saving, time-saving, and the irrigation effect is good. The investment in domestic equipment is about 700 yuan (fruit tree) -1400 yuan (green vegetables). Semi-fixed drip irrigation, the dry and branch pipes are fixed, and the capillary tubes are manually moved. The investment in mu is 500 yuan - 700 yuan. Mobile drip irrigation, the dry, branch, and capillary tubes are all manually moved, the equipment is simple, and the investment is saved compared with the semi-fixed drip irrigation, but the labor is more. The investment in mu is 2m yuan to 500 yuan.
