摘　　要：[目的]为建立马铃薯(Solanum tuberosum L.)垄沟集雨栽培技术提供参考。[方法]通过马铃薯不同垄膜宽度集雨效率比较试验,在进行土壤水分检测的基础上,观察测定出苗保苗率及增产效果,研究垄膜沟植技术的综合生产效益。[结果]马铃薯垄膜沟植技术下出苗率较平作、平作覆膜技术高,出苗提前,其中,30～60 cm垄膜宽度处理下表现较明显。增产效果最好的处理为40～50 cm垄膜宽度,增产幅度为23.2%～33.0%。[结论]垄膜沟植技术能够有效地提高马铃薯对雨水的利用效率,增加土壤根层含水量,提高马铃薯抗旱性和产量。[ Objective] The aim was to provide a reference for establish potato ridge-furrow and rainwater harvesting cultivation technology. [ Method] The rainwater harvesting efficiency comparison test of different ridge width planting patterns of potato was carried out, thereinto, based on the soil moisture determination, the comprehensive production benefit of potato ridge film and furrow planting technology was studied. [ Result] The seedling rate of potato ridge film and furrow planting technology was higher than that of the conventional tillage and the conven- tional tillage and film-mulching technology, and its seedling time advanced, thereinto, 30 -60 cm ridge film width treatment showed signifi- cantly. The best treatment was 40 - 50 cm ridge film width treatment, and its yield increasing amplitude was 23.2% - 33.0%. [ Conclusion ] The ridge film and furrow planting technology rises rainwater utilization technology of potato, increases the water content in rhizospheric soil, and imoroves potato＇ s drouabt resistance and vield.
