Semi-permeable mulching film

The utility model discloses a semi-permeable mulching film which comprises a first film, a second film and a third film. The second thin film is a permeable thin film; wherein the first thin films and the second thin films are alternately connected to form the mulching film which is formed by sequentially connecting the first thin films and the second thin films in the length direction. On a ridge surface needing film mulching, the mulching film covers the ridge surface, the first film is located at the crop transplanting position, and the second film is located on the ridge surface between every two adjacent crops. Therefore, after crops are transplanted, heat preservation and soil moisture conservation can be achieved through the first thin film, permeation and supplement of rainwater or water can be achieved through the position of the second thin film, heat preservation and water permeation are achieved, the films do not need to be uncovered in the whole growth period of the crops, and the advantages of h
