To investigate the optimal row spacing and fertilization regimen for rapeseed cultivation in the alpine region of Chahar Right Wing Banner,Ulanqab City,Inner Mongolia,a split plot experiment was conducted using'Jinya No.6'rapeseed as the study material.The experiment established 6 treat-ments(3 row spacings × 2 fertilization levels)with local traditional planting as the control(CK).Through measurements of rapeseed yield,oil content,and agronomic traits,the effects of different treatments on rapeseed production were analyzed.Results demonstrated significant interaction effects between row spacing and fertilization level on both yield and oil content.The 40 cm row spacing with high fertilization treatment achieved the highest yield(2 856.3 kg/hm2),representing a 14.2％in-crease over CK,and the highest oil content(42.3％),significantly higher than other treatments.Overall,the 40 cm row spacing with high fertilization treatment was identified as the optimal combination for high-yield and high-quality rapeseed production in the region.
