The invention discloses a method for jointly promoting potassium absorption of corn by using arbuscular mycorrhizal fungi and bacteria, and relates to the technical field of microorganisms, the method comprises the following steps: before corn planting, inoculating arbuscular mycorrhizal fungi inoculum in soil with the inoculum size of 500 spores/m < 2 >; after the corn is planted, a mixed bacterial agent with the thallus concentration of 1 * 10 < 8 >/mL is inoculated, and the inoculation amount is 200 mL/m < 2 >; wherein the arbuscular mycorrhizal fungus fungicide is glomus intraradices; the mixed bacterial agent is prepared by mixing rhodococcus, pseudomonas and ginseng earthy yellow soil source bacteria in equal proportion. The mixed inoculant of arbuscular mycorrhizal fungi and specific bacteria can take in soil quick-acting potassium more efficiently, so that the pressure of potassium supply is relieved, and the growth of corn is promoted. 本发明公开了一种利用丛枝菌根真菌和细菌联合促进玉米钾吸收的方法，涉及微生物技术领域，在玉米种植前，土壤中接种丛枝菌根真菌菌剂，接种
