摘要： Disclosed are a low-cost high-efficiency drip irrigation system for a cotton field and a use method thereof. The drip irrigation system for a cotton field includes a filtering device and a water supply device; wherein the filtering device adopts different types of single filtering devices or combined filtering devices according to different water source types; the water supply device includes multiple stages of main pipes, submain pipes and laterals; the laterals (a drip irrigation tape with labyrinth on one side or a drip irrigation tape inlaid with emitters inside) are laid on the surface of the ground and located below a mulch film. The drip irrigation system adopts the design of large flow (1.5-3.4 L/h), slightly larger pipe diameter (>75 mm), low water pressure (operating pressure of drip irrigation tape being 0.03-0.07 MPa) and suitable drip irrigation uniformity (80%-90%). The water and fertilizer management technology includes the technology of preserving seedlings in soil-moisture-insufficient cotton fields, and is matched with the drip irrigation system.
