摘　　要：盐碱地对马铃薯的出苗、生长以及产量均有很大的影响。该试验采用轻盐碱和重盐碱２组设计，对马铃薯品种进行适应性鉴定，试图选出适应性强，表现好的优良种质，以解决青海省西部大部分盐碱地品种缺乏的问题。试验结果表明，品种间差异极显著，抗（耐）盐碱弱的品种出苗较差，甚至出苗后又因盐碱过重而死亡，而抗（耐）盐碱较强的品种，一旦出苗即能健壮生长。轻盐碱和重盐碱２组试验间的产量差异亦极显著，轻盐碱地的产量明显高于重盐碱地。经筛选，青２９１４和固８２５无论在轻盐碱地或重盐碱地均表现高产。Soil salinity had great effects on potatoes' germination, growth and yield. The experiment was conducted in both light and heavy saline soils in Xining, Qinghai province. The objective of the trial was to select the best salinity tolerating potato varieties. The result indicated that varietal difference was very significant. The salinity susceptible varieties had poor emergence, retarded growth, even died soon after emergence, while salt tolerating varieties showed vigorous growth after emerging out of soil. The potatoes yield remarkably more in light saline soil than those in heavy saline soil. The varieties that showed the best performance were Qing 2914 and Gu825. The two varieties can be retried and used in salinity stricken areas.
