摘　　要：以青薯9号为试验品种,进行了马铃薯种块不同芽眼数对出苗率影响的对比试验,结果表明,处理A(1顶芽)出苗快、齐、状,出苗率最高,比处理E(4个侧芽)出苗率高6.7%,表现出较强的顶芽优势;侧芽时,随种薯芽眼数增多,马铃薯出苗率、生长量与种块芽眼数呈正相关。A comparative test about the effects of different numbers of buds of seed pieces on the germination rate of potato was carried out in 2015, the results showed that with the treatment A, the emergence was rapid, neat and vigorous and the germination rate was the highest, 6.7 percent higher than that of the treatment E, and a relatively strong apical dominance was showed; secondly, by the lateral buds, with the increase in the number of seed buds, the potato germination rate and growth were positively correlated with the bud numbers of the seed pieces.
