PROBLEM TO BE SOLVED: To provide an agricultural multilayer mulching film that optimally controls reflection of sunlight and has excellent preventive effects on rise in ground temperature and flying pests.SOLUTION: An agricultural multilayer mulching film, the one side of which is a light absorption layer 10 containing carbon blacks and the other side of which is a light reflection layer 11 containing titanium dioxide and metal fine particles, is characterized by the thickness of all layers ranging from 10 to 40μm, the thickness of the light reflection layer 10 ranging from 5 to 30μm, the concentration of titanium dioxide Cranging from 10 to 25 wt%, and the reflection rate of the light reflection layer 11 of 10% or more at the wavelength of 360 nm and ranging 60% to 80% at the wavelength of 450 nm. |
