The invention discloses a preparation method of a drip irrigation zone material with an inner inlaid paster. The preparation method comprises mixing 18-20% of linear polyethylene 7042, 19-20% of high pressure polyethylene TN26, 20% of HDPE-5000S, 25% of high density polyethylene 2480, 15% of an ethylene-vinyl acetate copolymer, 2.5% of carbon black, 0.2% of butylated hydroxytoluene, 1% of polyphthalamide, 0.3% of a synergistic agent A and 0.1% of a synergistic agent B, carrying out melting mixing through a double screw extruder, carrying out extrusion granulation at an extrusion temperature of 190-230 DEG C, carrying out cooling and carrying out loading to obtain the drip irrigation zone material with an inner inlaid paster.
