To explore the high-yield and high-quality cultivation mode of summer soybeans suitable for the ecological conditions of Jinping County, using the local main variety Qiandou No.12 as the material, three sowing methods and three fertilization levels were set up, resulting in a total of 7 treatments. The effects of different treatments on the agronomic traits, yield, and quality of soybeans were studied. The results showed that different treatments had significant effects on soybean plant height, number of pods per plant, number of seeds per pod, hundred-grain weight, and seed yield. Under the ecological conditions of Jinping County, the combination of wide and narrow row sowing (60 cm+40 cm) and 300 kg/hm² compound fertilizer was a preferable cultivation mode for achieving high yield and high quality of Qiandou No.12.
