Zusammenfassung:	The invention discloses a preparation method of super absorbent resin for inhibiting growth of weeds, sterilizing and promoting growth of crops, wherein the preparation method comprises the following steps: A, adding a neutralizer into acrylic acid to enable the neutralization degree of the acrylic acid to be 30-80%; B, adding acrylamide into the solution obtained in the step A, and stirring to react for 25-35 minutes; C, after the reaction in the step B is finished, sequentially adding 5-aminolevulinic acid, hymexazol, sodium 2,4-dichlorphenoxyacetate, potassium humate, a cross-linking agent and an oxidizing agent, stirring, introducing nitrogen, then adding a reducing agent, and carrying out stirring reaction; and D, after the reaction in the step C is finished, raising the temperature to 90-100 DEG C, and keeping the temperature for 2-2.5 hours. The water absorption rate of the super absorbent resin prepared by the preparation method is 820-1170 g/g, and the super absorbent resin has the functions of inhib
