Manufacturing method and application of bio-based degradable trap

The invention provides a manufacturing method and application of a bio-based degradable trap. The material for the bio-based degradable trap is prepared from the following raw materials in parts by weight: 85-90 parts of a bio-based material, 3-5 parts of calcium carbonate, 2-5 parts of pectin, 2-4 parts of viscose and 2-3 parts of a coloring agent. The manufacturing method comprises: placing rice straw, corn straw and cassava straw in biological straw into a crusher according to a ration, crushing into fragments, screening the fragments, placing the fragments and saw dust into a grinding machine, grinding into powder, screening the powder, placing the powder and waste paperboards put into a stirring pool, uniformly stirring, sucking pulp in a vacuum mode, injecting into a semicircular mold, placing in the open air for drying or drying, shaping by a hot-pressing shaping machine, and pressing into traps with various structures. According to the invention, the process is simple, the trapping effect is better, a
