摘　　要：由4个加工型马铃薯栽培品种脱毒微型薯原原种扩大繁殖微型小薯的试验结果表明:1)不同品种生产微型小薯的能力明显不同,其中Norvalley产量最高,达到9.04个/株;2) 块茎膨大期及时收摘微型小薯有助于产量及个数的提高,且以第2次(约50～55 d)收摘微型小薯的产量最高;3)直接利用微型薯原原种扩大繁殖微型小薯在产量和个数上明显高于植株打顶扦插的产量和个数;4)充足的种植空间有利于提高微型小薯个数与产量。In the present studies, 4 potato varieties of minitubers were used to produce the minitubers. It was found that minituber production ability was different in varieties, among which Norvalley formed the highest weight and number of minitubers per plant. The outputs and quantity of minitubers were improved by picking them in time and the highest outputs can be gained after 50～55days planting. The numbers of minituber produced by harvested minitubers is significantly more than that from cuttings. Good plant growing space could also increase output and quality of minitubers.
