This study evaluated the effects of no-till seeding and fertilization on restoration degraded grazing grasslands in Bayinbuluke. Poaceae species were selected for replanting, with Elymus dahuricus, Puccinellia distans, Festuca ovina mixed a 2:1:1 ratio. Four sowing rates applied: 0 g/m2 (A0), 2 (A1), 4 (A2), 6 (A3). Diammonium phosphate (N 18%, P2O5 46%) was used as fertilizer, four rates: (B0), 7.5 (B1), 15 (B2), 22.5 (B3). A total 16 treatments applied. The assessed changes grassland productivity, diversity, soil physicochemical properties. results showed that replanting significantly increased aboveground biomass by 81%, richness 55.8%, Shannon–Wiener diversity index 64.2%. Fertilization dry hay yield rising 60.9% to 81%. When fertilizer applied, contents phosphorus, nitrogen, available organic matter 43.4%, 50.6%, 66%, 31.2%, respectively. also improved stability aggregates, proportion large aggregates increasing 18.2%. findings suggest promote restoration, moisture nutrient availability being key drivers vegetation growth community diversity.
