摘　　要：【目的】为解决广西春薯种苗供应不足的问题,对甘薯种苗繁育技术进行研究。【方法】采用冬季温室地热种薯育苗和大田拱棚种苗繁育方法,开展甘薯春季种苗繁育技术研究,对比分析两种方法在种苗产量、育苗成本以及春薯生产之间的差异。【结果】温室大棚地热育苗方法种苗产出量为74万株/667m^2,百苗重为2.5kg,单株成本为0.075元,春薯栽插缺苗率为10.7%,鲜薯商品薯产量为1230.2kg/667m^2,单位面积纯收入为1260.2元/667m^2;大田拱棚育苗方法种苗产出量为1.5万株/667m^2,百苗重为4.5kg,单株成本为0.144元,春薯栽插缺苗率为7.1%,鲜薯商品薯产量为1706.5kg/667m^2,单位面积纯收入为2221.0元/667m^2。【结论】温室大棚地热种薯育苗方法是解决广西春种苗供应不足的有效方法。【Objective】In order to solve the issue of insufficient supply of spring potato seedlings in Guangxi,the technology of seedling breeding of sweet potato was studied.【Method】The spring seedling breeding technology of sweet potato was studied by applying the methods of winter greenhouse geothermal seed tuber seedling breeding and field arch canopy seed seedling breeding.The differences of seedling yield,seedling cost and spring potato production between the two methods were compared and analyzed.【Result】About the methods of winter greenhouse geothermal seed tuber seedling breeding,the yield of seedlings was 740 thousand plant/667 m^2,the weight of 100 seedlings was 2.5 kg,the cost per plant was CNY0.075,the lack of seedling rate was 10.7%,the yield of commercial tuber root was 1230.2 kg/667 m^2,and the net income per unit area was CNY1260.2/667 m^2.And in the method of field arch canopy seedling breeding,the yield of seedlings was 15 thousand/667 m^2,the weight of 100 seedlings was 4.5 kg,the cost per plant was CNY0.144,the lack of seedling rate was 7.1%,the yield of commercial tuber root yield was 1706.5 kg/667 m^2,and the net income per unit was CNY 2221.0/667 m^2.【Conclusion】The method of raising potato seedlings in greenhouse is an effective method to solve the shortage of spring potato seedlings in Guangxi.
