摘　　要：温室基质栽培中,马铃薯脱毒苗不同密度、不同扦插方式影响着微型薯的形成。对生长周期内苗的生长状况、成活率、收获后大于1 g的微型薯个数进行统计,结果表明:株行距为2.5 cm×10 cm一穴双株扦插苗长势好、成活率高、大于1 g的微型薯数量最多。Different density and different cuttage way of potato virus - free seedling effect growth of minipotato in the culture base in the greenhouse. This paper analysis the potato growth statement, survival rote, mounts of 〉 1 g mini - potato. The result show that the cuttage of potato virus - free seedling in distant of hills and rows 2.5 cm x 10 cm with double seedlings in one hole have good growth statement, high survival rate, the most mounts of 〉 1 g mini - potato.
