通过田间试验，研究了不同滴灌方式对马铃薯（Solanum tuberosum L.）研究了2008、2009和2010年西北干旱区地膜覆盖条件下马铃薯生长、块茎产量和品质以及水分利用效率的变化。2008年试验设不覆膜滴灌对照和覆膜滴灌4个频率处理：1次/d、1次/2d、1次/4d和1次/8d。2009年和2010年，在马铃薯的三个发育阶段，在-25kPa土壤基质势（SMP）下对无覆盖滴灌处理进行了灌溉，并在马铃薯发育阶段比较了四种不同的SMP滴灌策略（使用塑料薄膜）：S1（三个发展阶段期间的-25kPa SMP），S2（块茎形成和膨胀期间为− 25kPa SMP，成熟期间为− 35kPa SMP），S3（块茎起始和成熟期间的-25kPa SMP和膨胀期间的-35kPa SMP），S4（三个发育阶段期间的-35kPa SMP）。地膜覆盖对块茎产量、水分利用效率和块茎品质有负面影响。在覆膜的存在下，块茎产量，比重，淀粉含量和维生素C含量似乎提高灌溉频率的增加，但差异不显着。灌水频率对地膜覆盖下马铃薯水分利用效率无显著影响。对株高、产量和水分利用效率的分析表明，滴灌阈值为− 35kPa SMP时，干旱区马铃薯生长受到明显的水分胁迫。2010年覆膜条件下，S2滴灌处理的产量显著高于S3和S4，水分利用效率最高，块茎硬度显著高于其他处理。
Field experiments were conducted to study the effects of drip irrigation regimes on potato (Solanum tuberosum L.) growth, tuber yield and quality, and water use efficiency (WUE) when grown under plastic mulch in an arid area of Northwestern China in 2008, 2009 and 2010. The 2008 experiment consisted of a drip irrigation check without plastic mulch and four different drip irrigation frequency treatments with plastic mulch: once every day, once every 2days, once every 4days, and once every 8days. In 2009 and 2010 the drip check treatment without mulch was irrigated at −25kPa soil matric potential (SMP) during three potato development stages and four different SMP drip irrigation strategies were compared during the potato development stages (using plastic mulch): S1 (−25kPa SMP during the three development stages), S2 (−25kPa SMP during tuber initiation and bulking and −35kPa SMP during maturation), S3 (−25kPa SMP during tuber initiation and maturation and −35kPa SMP during bulking), S4 (−35kPa SMP during the three development stages). Plastic mulch negatively affected tuber yield, WUE, and tuber quality. In the presence of plastic mulch, tuber yield, specific gravity, starch content, and vitamin C content seemed to be enhanced as the irrigation frequency increased, although the differences were not statistically significant. Irrigation frequency did not affect WUE for potato grown under plastic mulch. Analysis of plant height, tuber yield and WUE showed that a drip irrigation threshold of −35kPa SMP led to obvious water stress for potato growth in this arid area. Under plastic mulch in 2010, S2 was the optimum drip irrigation regime because of the significantly higher yield than S3 and S4, the highest WUE and significantly firmer tubers than any of the other irrigation regimes tested.
