| 摘 要： | 马铃薯是西北黄土高原半干旱区的特色作物和主栽作物之一,如何提高其降水利用效率是发展该区域马铃薯产业的重点问题。在大田试验条件下,以不同的覆盖方式和沟垄种植方式为处理,测定马铃薯生育期的土壤水分含量及其分布和产量,计算耗水量和水分利用效率,研究西北黄土高原半干旱区旱地不同覆盖和种植方式对马铃薯产量和水分利用效率的影响。结果表明,马铃薯采用草-膜二元覆盖垄种技术,能够有效地积蓄自然降水,草-膜二元全地面覆盖保墒、垄沟有效地聚集和保持了土壤水分,尤其在伏旱阶段的块茎形成期,0-100cm土层的土壤含水量高于全膜覆盖处理。因此,高垄膜覆盖沟覆草垄播使得产量和水分利用效率较其它种植模式分别提高8.39%～58.38%和8.46%～67.97%,是一项适合于西北黄土高原旱作区马铃薯高产的栽培技术。

| Abstract: | It is the main way to increase rainwater use efficiency that conserve soil moisture by plastic membrane mulching and collect rainwater by field micro-furrow and ridge on dryland. Potato is the main arid and semiarid crop on northwest loess plateau,and the most important problem to develop local potato-industry is increase its rainwater use efficiency. The field experiment used the mulching methods and furrow-ridge planting model as the treatments,the soil moisture and soil water distribution,crop yield were... |
