摘　　要：地膜覆盖是干旱区作物种植的有效方法。马铃薯‘青薯9号’是定西市广泛种植的新品种,然而不同地膜覆盖方式对‘青薯9号’产量的影响目前仍不明确。试验研究不同地膜覆盖方式下土壤保水性以及‘青薯9号’的物候性状、经济性状和产量特性。结果表明,全膜大垄侧播+膜上覆土处理下土壤保水性最好,双垄全膜覆盖侧播方式下马铃薯‘青薯9号’平均块茎重和产量最高。研究可以为该地区马铃薯‘青薯9号’大面积推广中适宜种植方法的选择提供科学依据。Plastic mulching is an effective method for crop cultivation in arid area. ＇Qingshu 9＇ is a new potato variety cultivated widely in Dingxi City. However, the effects of different film covering modes on the growth and yield of ＇Qingshu 9＇remains unclear. In this study, the effects of different film covering modes on soil moisture contents, biological traits and yield of ＇Qingshu 9＇ were determined. The results showed that the plant under the treatment of full film and ridgeside seeding and covering soil on the film gave the best water retention, and under the treatment of double ridge plastic film mulching and side seeding gave the highest average tuber weight and yield compared with the other treatments. These results provide a scientific basis for appropriate cultivation method selection of ＇Qingshu 9＇ in large scale in Dingxi City.
