The present invention belongs to the technical field of biodegradable materials, and in particular relates to a novel composite biodegradable plastic material for injection molding and a preparation method therefor. The novel composite biodegradable plastic material for injection molding in the present invention is prepared from the following components, in parts by weight, of 40-70 parts of poly(butyleneadipate-co-terephthalate) (PBAT), 10-25 parts of bamboo fibers, 1-10 parts of poly(butylene succinate) (PBS), 1-10 parts of polylactic acid (PLA), 1-5 parts of fillers, 0.5-3 parts of plasticizers, 2-7 parts of lubricants, 0.1-1 part of a chain extender and 1-5 parts of antioxidants. The present invention provides the novel composite biodegradable plastic material for injection molding, which has desirable biodegradability, low raw material cost, high yield and high production efficiency. The present invention further provides a preparation method for the novel composite biodegradable plastic material for injection molding.
