针对黄土高原半干旱水资源短缺，水土流失严重，马铃薯播种面积大，但生产技术落后，缺乏对以收获地下块茎为主的具有良好水保功能保护性耕作技术的理论研究。本文通过大田试验，以传统耕种为对照比较研究了6种保护性耕作措施对马铃薯产量和水分利用效率的影响，结果表明，在黄土高原半干旱区，对于收获地下块茎的马铃薯，垄上覆膜沟内草膜双覆盖摆种、垄上覆膜沟内覆草浅播摆种和垄上覆膜沟内覆草摆种三种保护性耕作技术是可行的，三种技术的采用使各自的产量和水分利用效率较传统耕种分别提高30.0%、22.0%、17.2%和44.2%、27.4%、22.1%，且不降低马铃薯商品品质。

Water resource shortage and serious soil erosion are the main problems in the semi-arid region of the Loess Plateau in China, where potato is one of the dominant crops in the area. However, the potato cultivation technology is backward and the research and successful conservation til age practices for tuber crops like potato is sparse. Therefore, it is of great importance to develop suitable conservation practices for potato production in the semi-arid areas on the Loess Plateau. In this research, the tuber yield and water use efficiency of six conservation til age treatments were compared to conventional cultivation. Surface seeding in the stubble and the whole mulched with plastic film in furrow and ridge, shal ow seeding in the stubble of furrow and mulched ditch with plastic film mulched ridge, and surface seeding in the stubble of furrow and mulched with plastic film on the ridge were the suitable conservation til age cultivation technologies for potato. These practices could be adopted, and the tuber yield and water use efficiency were increased by 30.0%, 22.0%and 17.2%, and 44.2%, 27.4%and 22.1%, respectively, compared with conventional til age cultivation, meanwhile the quality of potatoes was not reduced.
