摘　　要：为研究大棚栽培技术与水溶肥料技术对脱毒早熟马铃薯商品薯种植的应用效果,在黄平实施水溶型复合肥不同用量对脱毒早熟马铃薯产量影响试验。结果表明追施40kg/667m^2(齐苗期、块茎形成期、块茎膨大期分别施8、16、16kg/667m^2)水溶肥处理的产量、株高和茎粗都效果最好,建议在生产中推广应用。To study the effect of irrigation of water - fertilizer on potato, different fertilizer rates was applied on virus - free early potato in Huangpign county. The results showed that the application of top dressing fertilizer 40 kg/667m2 （ application rates of homogeneous seedling stage ,tuber formations stage and tuber expansion stage are 8, 16, 16 kg/667m2） get the greatest yield and good agronomic traits such as plant height and stem diameter, so it was proposed on production of virus - free early potato.
