PROBLEM TO BE SOLVED: To provide an agricultural covering film which can prevent the trouble of crops due to direct light for a long term even in a condition that inside film surfaces of a lightly-closed greenhouse are drenched, is excellent in tear strength and heat retaining property, and is easily subjected to waste disposal as well. SOLUTION: A polyolefin-based resin film for agriculture is formed by including 5-10 wt.% of talc powder and 0.1-2 wt.% of a specific inorganic filler in a polyolefin-based resin, and has the diffuse transmittance of the whole film, the diffuse transmittance of the inside of the film, the total light transmittance of the whole film and infrared reflection absorptivity of >=50%, >=25%, >=80% and >=60%, respectively.
