摘　　要：[目的]了解甘薯种植行距和株距对产量构成要素的影响。[方法]以甘薯品种"冀薯98号"为材料,研究9种不同的株行距配置(行距0.80、0.70、0.60 m和株距0.20、0.25、0.30 m)对甘薯产量构成要素的影响。[结果]不同配置的种植方式会对甘薯茎蔓长、单株分枝数、二级分枝、单株茎叶鲜重、单株鲜薯重、薯藤比、单行甘薯重产生显著影响,但对单株结薯数未产生显著影响。[结论]根据甘薯生产不同的使用方向调整株行距配置方式,可达到最大生产效益。[Objective] The aim was to understand effects of sweet potato plant and row spacing configuration mode on yield elements.[Method]Taking ‘Hebei potato 98＇as materials,the effects of nine different plant and row spacing configuration mode on yield components of sweet potato were studied under the conditions of plant spacing 0. 80,0. 70,0. 60 m and row spacing 0. 20,0. 25,0. 30 m.[Result]The different configuration of planting methods could affect sweet potato stem,the number of branches per plant,two stage branch,fresh weight per plant,fresh tuber weight per plant,sweet potato rattan proportion and single sweet potato heavy,but could not affect the tuber number per plant.[Conclusion]According to the sweet potato production＇s directions for use,the plant and row spacing configuration mode is adjusted to achieve maximum production efficiency.
