摘　　要：以定薯1号为试验材料,在定西市安定区团结乡和定西市旱作农业科研推广中心两个试验点设置了白地膜全膜双垄沟播种、黑地膜全膜双垄沟播种、白地膜半膜垄上播种、黑地膜半膜垄上播种、白地膜半膜垄侧播种、黑地膜半膜垄侧播种和露地种植(CK)共7个处理的节水模式比较试验。结果表明:黑膜全膜覆盖的出苗率、大薯率、产量和成本均明显优于其他栽培模式,折合产量30 326 kg/hm2,较对照增产8 537 kg/hm2,增幅达39.2%,大薯率达82.3%。Seven different cultivation modes,i.e.white transparent plastic film covering the whole field,black plastic film covering the whole field,white transparent plastic film half covering with ridge planting,black plastic film half covering with ridge planting,white transparent plastic film half covering with ridge side planting,black plastic film half covering with ridge side planting,and planting without plastic film coverage（control）,were compared in the two sites of Tuanjie Township and Dryland Farming Research and Extension Center in Dingxi,using cv.Dingshu 1 as plant material.Emergence percentage,large sized tuber percentage,yield and production cost in the mode of black plastic film covering the whole field were all superior to other modes.In this mode,the yield could be reached 30 326 kg / ha,increasing 8 537 kg / ha（39.2%） as compared with the control,with big sized tuber percentage being 82.3%.
