Organic paper film for dry land covering cultivation and preparation method of organic paper film

The invention belongs to the technical field of agricultural application, and particularly relates to an organic paper film for dry land cover cultivation and a preparation method of the organic paper film. An organic paper film for dry land covering cultivation is prepared from the following raw materials in parts by weight: 35-55 parts of sugarcane leaves, 10-30 parts of bagasse, 15-30 parts of eucalyptus wood chips, 0.1-0.2 part of sodium carbonate, 0.5-1.0 part of a sizing material and 1.5-2.5 parts of kaolin. The organic paper film disclosed by the invention is used for covering dry land crops and has relatively high water retention, drought resistance and grass seed growth inhibition effects; after covering for 80 days, the organic paper film is gradually and naturally decomposed by soil microorganisms, so that organic matters in a plough layer of the soil are increased, the pH value of the acid soil is increased, and the effect of improving the soil fertility is achieved. 本发明属于农业应用技术领域，具体涉及一种用于旱地覆盖栽培的有
