摘　　要：通过对马铃薯脱毒微型薯4个粒重水平和4个密度水平进行比较试验，结果表明：在脱毒马铃薯一级原种的繁育中，为了提高种薯的整齐度，进而提高单位面积种薯的生产效率，微型薯大小应选用2～5g，播种密度以7000株／667m^2为宜。The randomized block design was conducted to study the effects of different potato weight and planting density on yield of first original seed potato in mini-potato with virus-free. The results showed that the mini-potato with from 2 to 5 g weight and 7000 plants/667 m^2 of planting density should be used to improve seed potato uniformity and seed potato yield in reproduction of first original seed potato with virus-free.
