Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation pipes, in particular to an assembled PVC drip irrigation pipeline. Background Art

[0002] Drip irrigation uses plastic pipes to deliver water to the roots of crops through holes or drippers on a capillary tube with a diameter of about 10 mm for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to increase fertilizer efficiency by more than double. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for irrigation of field crops in arid and water-scarce areas.

The layout of the entire drip irrigation pipeline requires connecting multiple branch pipes and then installing a bypass valve on the inside of the branch pipe, which takes a lot of time and has poor practicality. Therefore, it does not meet the existing needs. We propose an assembled PVC drip irrigation pipeline. Utility Model Content
