PROBLEM TO BE SOLVED: To provide an agricultural multilayer mulching film, which is light in weight and fits to the soil.SOLUTION: An agricultural multilayer mulching film has one surface which is a light absorption layer 2 comprising carbon black and linear low-density polyethylene, and the other surface which is a light reflection layer 1 comprising (a) high density polyethylene with high molecular weight, (b) linear low-density polyethylene, (c) low density polyethylene having the MI of 0.1 to 1.0 and the density of 0.925 to 0.935, (d) a white pigment. The light reflection layer 1 comprises, with respect to 100 pts.wt. of high density polyethylene with high molecular weight, 14 to 62 pts.wt. of linear low-density polyethylene and 2 to 40 pts.wt. of low density polyethylene. The thickness of the whole layer of the agricultural multilayer mulching film is 7 to 18 &mum, and the thickness of the light reflection layer is 5 to 13 &mum.
