Provided are a laminate for impeding plant ethylene reaction and a preparation method therefor. The laminate comprises at least a layer of high polymer composition and at least a layer of paper base, wherein the high polymer composition comprises an agent impeding plant ethylene reaction bonding position, a slightly-soluble or insoluble solvent, and a high polymer or copolymer dissolvable in the solvent and water. Also provided are a preparation method of the paper-base laminate and a method of inhibiting plant ethylene reaction. Further provided are an aluminum foil laminate or a corrugated board laminate for impeding plant ethylene reaction, which comprises at least a layer of high polymer composition and at least a layer of aluminum foil or corrugated board, wherein the high polymer composition comprises an agent impeding plant ethylene reaction bonding position, a slightly-soluble or insoluble solvent, and a high polymer or copolymer dissolvable in the solvent and water.
