为了探索机械化种植模式下微型薯生产原种的播种密度对产量的影响，本试验以‘克新1号’微型薯为试验材料，共设计了5个处理，行距为机械化播种行距90 cm，株距分别为15，12，10，9和7 cm。结果表明，试验所设种植密度间产量差异达极显著水平；以播种6000株/667m2产量最高，为2228 kg/667m2；考虑投入产出比最佳密度为6000~7000株/667m2，群体生长较合理，建议在乌兰察布地区大面积生产中推广应用。

In order to understand the effect of minituber planting density on yield under the condition of mechanization planting mode, five treatments were designed using minituber of‘Kexin 1’as plant materials. The row spacing was 90 cm. Planting distances were 15, 12, 10, 9 and 7 cm, respectively. The results showed that there was highly significant difference among tested treatments. The highest yield (2 228 kg/667m2 ) was obtained under the destiny of 6 000 plants/667m2. Considering input-output ratio, the best planting density was 6 000-7 000 plants/667m2. This density should be extended in production of‘Kexin 1’in Wulanchabu area.
