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%.

The invention discloses a method for inhibiting typical grassland artemisia annua of a Hagenberg temperate zone by mixed sowing configuration of indigenous dominant plants, and belongs to the technical field of grassland ecological restoration and vegetation regulation, and the technical scheme is as follows: spraying 70% saflufenacil water dispersible granule diluent for selective inhibition from the seedling stage to the initial branching stage of the artemisia annua; 30-45 days after spraying, a local dominant plant grass seed combination is resown, and the local dominant plant grass seed combination is composed of leymus chinensis, grass, elytrigia intermedium, astragalus melilotus and lespedeza daurica; 10-15 days after reseeding, 1 ton / mu of decomposed sheep manure organic fertilizer is applied. According to field verification, the biomass ratio of the artemisia annua is reduced by 76.71%, the biomass on the vegetation ground is increased by 73%-80% compared with a control group, the organic carbon on the soil surface layer is increased by 14.29%, and the rapidly available phosphorus is increased by 83.02%.
