The invention discloses chitin biological liquid-state three-dimensional degradable mulching film, and a preparation method thereof. The preparation method comprises following steps: chitosan is delivered into a constant volume dilution container, nanofiltered water of 40 to 45 DEG is added, and an obtained mixture is delivered into a stirring tank after a certain period of time; stirring is carried out in the stirring tank, and acetate acid gracial is added with stirring; after a certain period of time of stirring, ethanol is injected into the stirring tank for continuous stirring; after a certain period of time of stirring, a glyceryl alcohol is injected into the stirring tank for continuous stirring, then stirring is stopped, and an obtained mixed material is allowed to stand. According to the preparation method, chitin is extracted from marine organism shrimp and crab shells, is a pure biological source chitin raw material; spraying is adopted for mulching, so that voidless mulching with soil concave-conv
