A production method of plant fiber products is provided. A pulverized fiber-containing plant is fed into an internal mixer and kneader with a chemical pretreatment solution, achieving mechanical-physical modification and simultaneous chemical pretreatment modification of fibers. After expansion and modification in an expansion extruder, various additives and fillers are added and mixed by internal mixing and kneading, and the mixture is granulated by a pelletizer. Alternatively, the chemically modified plant fiber after internal mixing and kneading may be directly mixed with various additives and fillers, then expanded and extruded by an expansion extruder to produce granules or profiles. The granules or profiles prepared above can be used to produce plant fiber products of various shapes and properties, as well as sheets, profiles, paper, films and other plant fiber products by using existing equipment and process principles such as plastic injection molding machines, extruders, blow molding machines, rubber mixers, calenders, hot presses, microwave, infrared and steam baking. These products can replace plastics, plastic foams, wood products, paper and films.
