中文摘要	通过垄沟集雨种植马铃薯试验,研究了不同垄沟集雨种植模式对土壤蒸发的影响.结果表明,在马铃薯全生育期,垄上覆盖塑料薄膜(CR)处理土壤蒸发量为122.9～165 mm,垄上原土夯实不覆膜(UR)处理土壤蒸发量为90.9～101.2 mm,无垄带状种植(CK) 土壤蒸发量为80.7 mm.其中,覆膜垄处理CR60在马铃薯成熟期土壤蒸发强度最大,达2.6 mm·d~(-1),平均为1.46 mm·d~(-1),而对照的土壤蒸发强度为0.65 mm·d~(-1);不覆膜土垄处理(UR30)土壤蒸发强度苗期最小,只有0.2 mm·d~(-1),平均为0.39 mm·d~(-1),而对照的土壤蒸发强度为0.58 mm·d~(-1).在马铃薯生长的现蕾期和开花期,水面蒸发量最大,日平均水面蒸发量分别为8.3和9.0 mm,与土壤蒸发不同步.马铃薯成熟期,各处理棵间土壤蒸发量都达到最大值.覆膜垄蒸发量最大,集雨效果显著,所以应采取抑制土壤蒸发措施,以便进一步提高水分利用效率.
英文摘要	This paper studied the soil evaporation in potato field in semi-arid area under effects of covering ridge with plastic film (CR) , uncovering ridge but compacted (UR) , and belt planting on flat soil without ridge (CK). The results showed that in the whole growth season of potato, soil evaporation was 122.9-165mm, 90.9-101.2 mm, and 80.7 mm under CR, UR, and CK, respectively. Treatment CR_(60) had the maximum soil evaporation (2. 6 mm ·d~(-1)) at maturing stage, with a mean of 1.46 mm ·d~(-1), while the soil evaporation in CK was 0. 65mmod~(-1). In treatment UR_(30), soil evaporation was the minimum (0.2mm·d~(-1)) at seedling stage, with a mean of 0. 39 mm ·d~(-1), while CK was 0.58mm ·d~(-1). However, water surface evaporation was the maximum at budding and flowering stages, with the daily average evaporation being 8. 3 mm and 9. 0 mm, respectively , and not in-phase with soil evaporation. At maturing stage, soil evaporation was the maximum in all treatments. It was suggested that covered ridge had high efficiency of rainfall harvesting , but owing to its maximum soil evaporation, measures should be taken to inhibit soil evaporation to increase water use efficiency.
