Full-biodegradable mulching film material for tobacco planting and preparation method thereof

The invention discloses a full-biodegradable mulching film material for tobacco planting, and relates to the technical field of biodegradable mulching film preparation. The full-biodegradable mulching film material for tobacco planting is prepared from the following raw material components in parts by weight: 60 to 100 parts of poly(p-dioxanone), 1 to 5 parts of furandicarboxylic acid-succinic acid-propylene glycol copolymer, 1 to 20 parts of polylactic acid, 1 to 10 parts of starch, 1 to 5 parts of a compatilizer, 0.1 to 1 part of a heat stabilizer, 0.01 to 1 part of an antioxidant, and 5 to 15 parts of a biodegradation agent. The polylactic acid and starch are used for modifying poly (p-dioxanone), the furandicarboxylic acid-succinic acid-propylene glycol copolymer improves the heat preservation and entropy preservation performance of the mulching film, the requirements of tobacco in the early growth stage are met, the polymers are all biodegradable resin, degradation of the polymers is promoted by adding a
