摘　　要：本试验用亚硫酸氢钠(NaHSO_3)作为光呼吸抑制剂喷施甜椒(C.annuum L.);试验结果表明.亚硫酸氢钠能促进甜椒生长发育(株高、茎粗、单株果数和果重均有所增加),提高净光合生产率,增产达10～30％,以200ppm喷施2～3次为最佳处理组合.Sodium hydrogen sulfate (NaHSO_3) was applied on bell pepper (C. annuum L.) as a photorespiration represser to test its effect on yield. NaSO_3 sprays promoted plant height, stem diameter, fruit numbet and plant weight and increased the net assimilation rate and yield. Concen-tratiens 60, 100, 120, 180, 200, 240 and 300 ppm were all effective, and the optimum concentration was 200 ppm. Spraying 3 times at a 7-day interval was the most effective on increasing the growth and yield of bell pepper.
