摘　　要：采用田间小区试验和室内分析相结合的方法,研究了露地平播、平作行上覆膜、双垄全膜覆盖、起垄行上覆膜及起垄覆膜膜侧播种五种不同覆膜方式对旱作马铃薯若干生理指标的影响,旨在探讨适合内蒙古武川县旱作马铃薯栽培的覆膜方式。结果表明,四种覆膜方式均能不同程度提高旱作马铃薯叶片相对含水量、可溶性蛋白含量,并使叶片超氧化物歧化酶活性、丙二醛含量、游离脯氨酸含量处于较低水平,以维持植株正常的生长代谢,其中以起垄覆膜膜侧播种和双垄全膜覆盖两种覆膜方式的效果最好。The experiment, combining field experiment with laboratory analysis, was conducted to study the changes in physiological indexes under different film^covering modes （the traditional planting, harrowed bedding planting with film mulching, double ridges mulched completely by film, ridge mulched by film, and ridge culture mulched by film and ridge side planting）, and to identify the best film-covering mode under the dryland tillage potato of Wuchuan county, Inner Mongolia. The results indicated that film-covedng modes could improve the leaf relative water content and soluble protein content to some extent, and keep the leaf superoxide dismutase （SOD） activity, malondialdehyde （MDA） content, and free proline content at relatively low level to maintain the normal metabolism of plants. The double ridges mulched completely by film, and ridge culture mulched by film and ridge side planting had the best effect.
