通过开展马铃薯种薯覆膜与露地滴灌田间试验,研究水分对马铃薯种薯产量的影响及马铃薯耗水规律.结果表明：覆膜地马铃薯种薯产量极显著地高于露地马铃薯种薯产量;不灌水处理马铃薯种薯产量极显著地低于其他各灌水处理,灌溉定额越大,马铃薯种薯产量越高;灌溉定额一定,产量、耗水量和耗水模系数及水分利用效率均呈灌水2次〉灌水1次〉灌水3次的规律;灌溉定额越大的处理耗水量越大,在全生育期马铃薯的耗水规律为现蕾期〉花期〉苗期〉成熟期,现蕾期耗水量最大.露地比覆膜耗水量大18.43 mm,膜下滴灌马铃薯的水分利用效率明显高于露地,说明膜下滴灌马铃薯技术有利于保持土壤水分,有效节约水资源,适宜在宁夏中部干旱地区广泛推广.

Based on the study of field experiments,water consumption regularities and soil water effecting yield of potato.The results show that the yields of potato in mulch cover land are obliviously higher than in bare land,the more irrigation quota,the higher of the yields and water consumption of potato;the law of yield,water consumption,water consumption coefficient and water use efficiency of potato were tested 2 times irrigation water〉1 irrigation water〉3 times irrigation water〉 no irrigation.The law of water consumption is buding〉florescence〉seedling stage〉maturity;water consumption of bare land is higher than that of mulch cover,water use efficiency with mulch cover is obviously higher than that with bare land.It shows that mulch cover drip irrigation can save water resource,and is feasible in the middle dryland of Ningxia.
