Abstract
The utility model discloses a permeable mulching film, which is divided into an upper layer and a lower layer. The upper layer and the lower layer are adhesively connected through a certain width and form minimal square units. Each square upper layer film center and the four corners of each square lower layer film are respectively provided with an opening. The gaps between the upper layer films and the lower layer films form rainwater channels. During a water supplementing or rainwater using process, water first flows to the opening on each upper layer film and then to the openings of each lower layer film through the gap between the two layer films and finally to the ground surface. When no water is supplemented, the mulching film has one to two layers covering the ground surface due to the fact that the opening on each upper layer film and the openings on each lower layer film are mutually staggered and thus the steam is kept inside the mulching film. The mulching film in the utility model can be widely applied in water deficient areas for agricultural productions and desertificated land treatment, etc. on a large scale.
