中文摘要	为研究和解决阴山北麓农牧交错带地区降水资源不足、雨养农业产量不稳的问题,于2011 ~ 2012年在内蒙古武川县进行了不同垄宽和沟宽的集雨措施栽培马铃薯的试验,测定了沟垄集雨处理下土壤水分状况、马铃薯生长、产量和水分利用效率。结果表明:沟垄集雨技术提高了种植区土壤水分,增幅16.1% ~ 26.0%。马铃薯生育期内的叶面积指数和单株干物重均高于对照处理。沟垄集雨处理的商品薯率较平作高5.0 ~ 30.5%,商品薯产量高于平作,垄宽1.0m沟宽1.0m集雨处理商品薯产量平作增产52.0% ~ 81.0%。较平作相比,集雨处理提高了马铃薯水分利用效率。沟垄集雨技术对阴山北麓农牧交错带地区雨养农业规避干旱气候风险以实现马铃薯稳产具有重要的应用价值。
英文摘要	To solve the problems about rainfall limitation and instability yield in rain - fed agriculture in the north foot of Yinshan Mountain,a series of field rainwater harvesting experiments were conducted in a potato field in Wuchuan County in Inner Mongolia,China. The study evaluated the effects of different ridge and furrow widths on soil moisture,potato growth and yield,and water use efficiency. The results indicated that rainwater harvesting treatments promoted the soil water storage in 20 ~ 50cm depth,leading the leaf area index(LAI) and single plant dry weight higher than the control treatment. Compared to the control treatment,rainwater harvesting treatments increased the commercial potato ratio by 5.0 ~ 30.5%,and also increased commercial potato yield. The NM1.0 treatment produced the greatest effects on crop yield,and significantly increased commercial potato yield by 52.0% ~ 81.0% compared to control. Water use efficiency (WUE) values for the rainwater harvesting treatments were higher than that for the control treatment,thereby farmland productivity being improved. Ridge and furrow rainwater harvesting was an efficient technique for rain - fed agriculture to avoid arid climate risk,achieve stable production in north ecotone region.
