The invention provides a preparation method of plastic with a rapid biodegradation characteristic, which comprises the following steps: preparing corn collected in the current year, and then preparing the corn into corn starch; adding water into a stirrer, then adding the corn starch prepared in the first step into the stirrer to be mixed with the water, and after the corn starch and the water are completely mixed, adding ingredients into the stirrer to be further stirred; starch and water are added into a stirrer to be stirred, ingredients are added into the stirrer to be continuously stirred after stirring of the stirrer is completed, plastic raw materials can be obtained after stirring is completed, then the raw materials are conveyed to a heat extruding machine through a turnover vehicle, and the raw materials are put into the heat extruding machine to be extruded into plastic in the corresponding shape. And then the extruded raw materials are put into a cooling chamber to be cooled, so that the final pla
