1. A method for preparing a green slow-release preservative paper used for fruit and vegetable preservation, comprising:

step 1: preparing an aqueous solution or ethanol solution of a biological preservative with a concentration, soaking an absorbent paper in the solution, taking out the absorbent paper after complete impregnation, and drying or airing at room temperature, to obtain a core paper loaded with biological preservative;

step 2: taking an amount of β-cyclodextrin-embedded 1-methylcyclopropene as a fruit and vegetable respiration inhibitor, and uniformly loading on a surface of an absorbent paper coated with an adhesive, to obtain a base membrane loaded with fruit and vegetable respiration inhibitor; and

step 3: applying an adhesive on both sides of the core paper loaded with biological preservative, placing the base membrane loaded with fruit and vegetable respiration inhibitor with the same area on one side, placing an air-permeable paper with the same area on the other side, and then heating and pressing to obtain the green slow-release preservative paper.
