以马铃薯克新1号品种为试验材料，采用随机区组设计，在阴山北麓地区连续3a定位施肥，研究了不同肥料配施对马铃薯产量和水分利用效率的影响。结果表明：马铃薯各施肥处理各生育时期0～80 cm土壤含水量均低于对照，全生育期总耗水量较对照提高0．17％～4．16％，干物质积累量明显高于对照；肥料配施条件下各施肥处理马铃薯产量和商品薯率较对照显著提高，增产幅度和商品薯率的增加幅度分别为5．8％～49．67％，13．97％～55．14％，以M＋NPK处理效果最明显，2011年和2012产量分别达到36863．70 kg·hm－2和31386．14 kg·hm－2，其次是NPK处理和M处理；各施肥处理的水分利用效率均高于对照，其中以M＋NPK处理最高，两年分别较CK处理高出43．72％和44．09％，与其它各施肥处理相比差异显著，其次为NPK处理和M处理。有机肥和氮磷钾肥配施是最适合当地马铃薯种植的肥料配比。

Taking the potato variety of“Kexin 1”as the experimental material ,using randomized block design ,has studied the effects of different fertilizer on potato yield and water use efficiency ,which was experimented for consecutive three years of fertilization at northern foot of Yinshan Mountain .The results showed that:For all fertilization treatments and potato growth stages ,the soil moisture content in 0~80 cm was total lower than the control group .The total water consumption in whole growth period was increased 0 .17% ~4 .16% comared with control;the dry matter accumulation was significantly higher than control .The potato yield and commodity rate of each treatment were significantly higher than control under fertilization condition;the increasing amplitudes of yield and commodity rate were achieveed 5 .8% ~49 .67% and 13 .97% ~55 .14% ,respectively .The effect of M+NPK treatment was the most obvious ,the yield in 2011 and 2012 was reached 36 863 .70 kg·hm-2 and 31 386 .14 kg·hm-2 ,respectively .The next was the NPK and M treatment .The water use efficiency of all fertilization treatments were total higher than the control .Among them ,the M+NPK treatment was the highest in two years was higher 43 .72% and 44 .09% than CK ,follow by the NPK and M treatment .Combined organic fertilizer with NPK was the most suitable fertilizer ratio for local potato planting .
