摘　　要：为探索马铃薯宣薯2号在贵州中部地区的最佳种植方式、种植密度,设置该试验。结果表明:密度对宣薯2号产量和效益有极显著影响,行距对产量无显著影响。在该试验条件下,密度与产量及商品薯产量成正相关,密度种植3 500～5 000穴/667 m2均能获得较好的经济效益。This study was focus on the ideal planting pattern and planting density for potato eultivar Xuan-potato-2 in the central area of Guizhou province. The results showed that planting density had a very significant influence on the yield of potato cultivar Xuan-potato-2, while no dramatic relationship was found between row spacing and yield. Under the test conditions, both total yield and marketable tuber yield of Xu- an-potato-2 were positively correlated with planting density. The planting density of 3 500 -5 000 holes/bin2 is suitable for the production of Xuan-potato-2 in the central Guizhou area.
