研究了不同起垄覆盖方式对陇薯7号、冀张薯8号、庄薯3号生育期、主要性状及产量的影响。结果表明，在黑膜覆盖垄上覆土方式下，庄薯3号、冀张薯8号、陇薯7号折合产量分别为32 840、46 490、41 050 kg/hm2，较对照露地栽培增产显著，增产率分别达到31.85%、35.25%、18.90%。综合考虑认为，陇薯7号、冀张薯8号综合农艺性状、产量表现较优，适宜在庆阳市种植，北部县区推荐选用黑膜覆盖垄上覆土方式，南部县区推荐选用玉米秸秆带状覆盖方式。

The effects of different ridge-forming and film-covering modes on growth period， main characters and yield of Longshu 7， Jizhangshu 8 and Zhuangshu 3 were studied. The results showed that the yields of Zhuangshu 3， Jizhangshu 8 and Longshu 7 under the black film mulching ridge were 32 840， 46 490 and 41 050 kg/hm2， respectively， significantly higher than those of the control of open cultivation， with the increase rates of 31.85%， 35.25% and 18.90% respectively. It is considered that Longshu 7 and Jizhangshu 8 had the best comprehensive agronomic traits and yield performance. They were suitable for cultivation in Qingyang City. Black film mulching on ridges was recommended in northern counties， and belt mulching with corn straw was recommended in southern counties.
