The invention discloses a nano pectin coating-containing preservative film special for pitaya and a preparation method thereof, and belongs to the technical field of preservative films, the nano pectin coating-containing preservative film special for pitaya comprises a polyethylene film and a nano pectin coating coated on the polyethylene film, and the coating weight of the nano pectin coating is 1-7g/m < 2 >. The nano pectin coating is prepared from the following raw material components in parts by weight: 1-3 parts of pectin; 0.5-1 part of dehydroacetate intercalated hydrotalcite powder; 40-60 parts of distilled water; and 30-50 parts of glycerol. The preparation method of the preservative film special for the pitaya comprises the step of smearing the nano pectin coating in the preservative film special for the pitaya and containing the nano pectin coating on the surface of the polyethylene film through a coating machine. The preservative film can effectively inhibit the growth of bacteria, prolongs the she
