In the Erhai Basin，rice is one of the most significant food crops.Irrational fertilization practices have reduced rice yields and production values，and the high nitrogen and phosphorus losses in paddy fields pose a challenge to the prevention and control of non-point source pollution in Erhai Basin.The effect of organic-inorganic green intelligent fertilizers on rice yield and environmental emissions in the Erhai Basin was investigated to provide theoretical basis for rational fertilization of rice in Erhai Basin.A field experiment was conducted in Dali Bai Autonomous Prefecture，Yunnan Province，in 2022，with four fertilization treatments of no fertilization，chemical fertilization alone，organic fertilization alone and organic-inorganic green intelligent fertilization，to analyze rice yield and its constituent factors，nitrogen utilization efficiency，ammonia volatilization，runoff nitrogen and phosphorus losses and chemical oxygen demand of the runoff water，and production value.The results showed that:(1) Rice yield were increased by 44.4%，20.8% and 68.1% in chemical fertilization alone，organic fertilization alone and organic-inorganic green intelligent fertilization treatment，respectively，compared with no fertilization treatment，with the organic-inorganic green intelligent fertilization treatment having the highest rice yield.The organic-inorganic green intelligent fertilization treatment mainly increased the number of spikes and grains of rice，which in turn increased the rice yield.(2) The aboveground nitrogen accumulation of the organic-inorganic green intelligent fertilization treatment was significantly higher than that of the chemical fertilization alone and organic fertilization alone.Nitrogen apparent recovery efficiency，nitrogen agronomy utilization efficiency，nitrogen physiology efficiency and nitrogen partial factor productivity of the organic-inorganic green intelligent fertilization were 12.5%，8.8 kg/kg，9.0 kg/kg and 13.0 kg/kg higher than those of the chemical fertilization alone，respectively.(3) Ammonia volatilization，nitrogen，phosphorus losses were reduced by 63.3% and 56.3%，38.1% and 41.4%，6.5% and 14.4%，respectively，for the organic fertilization alone and organic-inorganic green intelligent fertilization，and the nitrogen surpluses were reduced by 41.5%，compared to the chemical fertilization alone treatment.(4) The net profit of the organic-inorganic green intelligent fertilization treatment was 27000 and 24000 Yuan/hm² higher than that of the chemical fertilization alone and organic fertilization alone treatment，respectively.The organic-inorganic green intelligent fertilization treatment significantly increased the number of grains and spikes，and consequently the rice yield，and the rice nitrogen accumulation and nitrogen fertilizer utilization were significantly increased.At the same time，the chemical fertilization alone treatment reduced soil ammonia volatilization，nitrogen and phosphorus runoff loss and soil nitrogen surplus compared with traditional fertilization pattern.Therefore，the application of organic-inorganic green intelligent fertilizer could achieve high yield，high efficiency，emission reduction and value-added synergistic effect of rice in Erhai Basin.
