Abstract: 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%).

Abstract: A membrane bearing device, a membrane attaching apparatus and a method for attaching a membrane are provided in embodiments of the disclosure. The membrane bearing device includes: a base plate, comprising a first bearing surface configured to bear a membrane; and a roller, which is rotatably mounted onto the base plate, and is configured to transfer and attach the membrane from the first bearing surface to a substrate onto which the membrane is to be attached, by rolling on the membrane.
