The application discloses a method for inhibiting Artemisia annua in a Hulunbuir typical grassland by using mixed sowing of local dominant plants, and belongs to the technical field of grassland ecological restoration and vegetation regulation. The technical scheme is as follows: during the seedling stage to the initial branching stage of the Artemisia annua, 70% bensulfuron-methyl water dispersible granules are sprayed to perform selective inhibition; 30-45 days after the spraying, local dominant plant grass seeds are supplemented and sowed, and the local dominant plant grass seeds are composed of Leymus chinensis, Leymus mollis, Thinopyrum intermedium, Melilotus officinalis, and Lespedeza davurica; 10-15 days after the supplement and sowing, 1 ton of decomposed sheep manure organic fertilizer is applied per mu. Field verification shows that the application can reduce the biomass proportion of the Artemisia annua by 76.71%, increase the aboveground biomass of the vegetation by 73%-80% compared with a control, increase the organic carbon in the surface layer of the soil by 14.29%, and increase the available phosphorus by 83.02%.
