Description

Technical Field

[0001] The utility model relates to the technical field of water-saving equipment, in particular to a mulch film drip irrigation device for agriculture. Background Art

[0002] Drip irrigation is a highly efficient, water-saving irrigation method that delivers water and nutrients directly to the root zone of crops through a low-pressure piping system, where they are slowly released in the form of drips. This irrigation method precisely controls water volume, reduces evaporation and seepage losses, and significantly improves water use efficiency. Drip irrigation is widely used in orchards, greenhouses, nurseries, and for the cultivation of high-value cash crops. It is particularly effective in arid and water-scarce regions and plays a vital role in promoting sustainable agricultural development.

[0003] Chinese utility model patent publication number CN221355167U discloses a water-saving agricultural mulch drip irrigation device. The device comprises an annular upper plate with an annular groove on its lower surface; an annular lower plate with an annular upper projection corresponding to the groove. The upper projection fits into the groove to clamp the mulch film. The mulch film is sealed by engaging the groove on the upper plate with the upper projection on the lower plate. However, when the upper projection is inserted into the groove, the mulch film sandwiched between the two is squeezed and deformed, making operation laborious and slow. Utility Model Content
