摘　　要：本研究探讨施用不同配比肥料对甘薯产量和品质的效应，结果表明：甘薯施用钾肥和腐植酸（ＨＡ）配施鲜薯、鲜蔓产量均为最高，与对照相比，经统计分析均达极显著水平。钾肥和ＨＡ配合能改善甘薯品质，其蛋白质、可溶性糖、维生素Ｃ和胡萝卜素等含量均明显提高。This study probes into the different effects of different fertilization rations on the yield andquality of sweet potato.The experimental results show that appling potash fertilizer combinedwith HA(humic acid)is most favourable to the yields of fresh tuber and vine.Moreover ap-pling potash fertilizer combined with HA improres the quality of sweet potato.Its contents ofprotein,soluble sugar,vitamin c and carotine are raised distinctly.
