中文摘要	在陇中半干旱区设置玉米整秆带状覆盖(ST)、地膜覆盖(PT)2种覆盖方式,以露地平作为对照(CK),研究了不同覆盖方式对马铃薯田土壤水分、耗水规律、产量及水分利用效率的影响。结果表明:与CK相比,覆盖处理显著(P<0.05)提高了马铃薯播种至收获期0~200cm土壤贮水量,ST和PT处理土壤贮水量较CK的增幅分别以收获期(12.3%)和淀粉积累期(9.1%)最大;覆盖处理降低了马铃薯全生育期耗水量,以ST处理的降幅最大(23.4%);与CK相比,ST处理显著降低了生育前期(播种-块茎形成期)和后期(淀粉积累期-收获期)的耗水量,显著增加了生育中期(块茎形成期-淀粉积累期)耗水量,并增加了深层土壤水分,而PT处理主要降低了生育前期和中期耗水,显著增加了生育后期耗水;ST和PT处理分别使马铃薯产量较CK显著增加32.4%和32.9%,水分利用效率提高73.8%和48.8%。综上可知,玉米整秆带状覆盖处理能显著改善马铃薯生育中后期0~200cm土壤水分状况,使马铃薯关键生长阶段耗水增多,能显著提高马铃薯产量和水分利用效率。
英文摘要	We examined the effects of different mulching practices on soil moisture,water consumption characteristics,tuber yield,and water use efficiency of potato field,by setting up two kinds of whole maize straw strip mulching (ST) and plastic film mulching (PT) in a semi-arid area of central Gansu,with bare-flat land (CK) as control.The results showed that both mulching practices significantly increased soil water storage in 0 - 200 cm profile during sowing to harvest stages (P<0.05).Soil water storage peaked during the harvest stage under the ST treatment(12.3%) and during starch accumulation stage under PT treatment (9.1%),respectively.Water consumption of potato under both mulching practices during the whole growing stage was lower than that of CK,with the largest decrease (by 23.4%) under the ST practice.The ST pattern significantly reduced soil water consumption in the early (from sowing to tuber initiation) and later growth stage (from starch accumulation to harvest),while significantly increased soil water consumption in the middle growth stage (from tuber initiation to starch accumulation) and increased deep soil water storage.By contrast,PT practice mainly reduced soil water consumption in the early and middle growth stage and significantly increased soil water consumption in the later growth stage.ST and PT practices significantly increased tuber yield by 32.4% and 32.9%,and water use efficiency by 73.8% and 48.8%,respectively.In conclusion,the whole maize straw strip mulching can significantly improve soil moisture in 0-200 cm soil layer in the middle and late growth stage of potato,increase soil water consumption in the critical growth stage of potato,and thus significantly improve potato yield and water use efficiency.
