The invention provides preparation and application of a nanocellulose antibacterial anti-oxidation fresh-keeping composite film with high-strength ultraviolet shielding. The film comprises the following main components: base material water chestnut hull nanocellulose, antibacterial agent silver nanoparticles, film-forming agent polyvinyl alcohol, plasticizer glycerol and green reducing agent Eupatorium japonicum peel extract, the components are uniformly mixed to obtain composite film liquid, and the composite film liquid is dried at 37 DEG C to form a film. The nano-cellulose antibacterial anti-oxidation fresh-keeping composite film with the high-strength ultraviolet shielding function is obtained. The high-strength ultraviolet-shielding nano-cellulose antibacterial anti-oxidation fresh-keeping composite film prepared by the preparation method disclosed by the invention utilizes the waste water chestnut shells and the scabish peel, so that the cost is low, and the prepared film has high-strength ultraviolet
