For this purpose, the width of the film to be covered can be adjusted to facilitate fixing on both sides of the soil covering film. Then, the handle 35 is turned to make the threaded rod 34 drive the telescopic plate 33 to move upward or downward, and the height of the plow 32 is adjusted to change the thickness of the soil turning, thereby changing the amount of turned soil, so that different soils can be covered according to different films, so as to avoid that too little soil is covered, which may cause the film to be blown away when the wind blows and affect seed planting. Then, the user puts one end of the film It is pulled out from the coating roller 4, moved to a suitable position and fixed by covering it with soil. The user moves the mounting frame 1 through the driving equipment. Since one end of the film is pulled out and fixed, the film on the coating roller 4 can be gradually moved out during the movement of the mounting frame 1. At the same time, the movement of the plowshare 32 can turn the soil. The turned soil is squeezed by the plowshare 32 and moved toward the middle of the mounting frame 1 to cover the upper side of the film, completing the soil covering and fixing of the film. The middle part of the film can be pressed by the resistance wheel 9 to prevent the film from bulging high when there is wind, affecting the covering and fixing of the soil on the film.
