摘　　要：本文对甘薯品种回笼火炕育苗技术进行了研究,结果表明:回笼火炕育苗一窝红出苗190棵,移栽成活率95%,最高;农家种其次,出苗186棵,移栽成活率达93%;第3是对照徐薯18,移栽成活率92%;第4是鲁薯2号,移栽成活率87%;第5是遗薯3号,移栽成活率78%。一级苗试验甘薯平均鲜重折合亩产:回笼火炕育苗产量表现是4个品种分别比徐薯18(ck)增产47.7%、9.3%、20.8%、79.5%;二级苗试验甘薯平均鲜重折合亩产:回笼火炕育苗产量表现是一窝红、农家种分别比徐薯18(ck)增产7.8%和13.1%,鲁薯2号、遗薯3号分别比徐薯18(ck)减产5.1%和5.2%。在北方包头地区回笼火炕育苗有利于甘薯生长和出苗、薯块形成和膨大,增产显著,为最佳的育苗方法。在包头地区引进和推广甘薯栽培对于包头地区的种植结构调整,提高农民的经济收入具有重要意义。The paper is about growing seeding technique by circulated hotbed of sweet potato.It shows： The first is Yi-wohong,came out 190,transplant rate is 95%,The second is Nong-jiazhong,came out 186,transplant rate is 93%.The third is contrast Xu-shu 18,transplant rate is 92%.The fourth is Lu-shu 2,transplant rate is 87%.The fifth is Yi-shu 3,transplant rate is 78%.The First seeding test shows： Four breeds by circulated hotbed increased production by 47.7%;9.3%;20.8%;79.5%.The second seeding test shows： Yi-wohong and Nong-jiazhong by circulated hotbed increased production by 7.8% and 13.1% than Xu-shu.Lu-shu 2 and Yi-shu 3 decreased production by 5.1% and 5.2% than Xu-shu.The circulated hotbed technique is to the benefit of seeding、growing and increasing production in Baotou areas,so it is the best method.It is of far reaching importance to adjust the planting structure and increase farmers＇ income in Baotou areas.
