[PROBLEMS] A light reflection sheet for cultivation that reflects light for plant cultivation, has high resource saving, biodegradability and low environmental impact, and has excellent light reflectivity, heat retention, and flexibility. The present invention also provides a light-reflective sheet for biodegradable cultivation that is thin, lightweight, excellent in laying workability, and effective in controlling pests. A biodegradable light reflecting sheet for biodegradable cultivation comprising a biodegradable resin foam or a porous body having fine bubbles or pores therein. In this case, the average bubble diameter or average pore diameter of the bubbles or pores is preferably not less than the wavelength of light and not more than 50 μm. Further, it is preferable that the thickness of the sheet is 100 μm or more, the specific gravity is 0.7 or less, and the diffuse reflectance of light is 85% or more. [Selection figure] None |
