摘　　要：针对宁南山区一年一熟,光热资源丰足有余,一年两熟又显不足的气候、自然特点进行全膜覆盖双垄集雨沟播玉米套种大豆的研究。结果表明,该种植模式生态、经济、社会效益十分明显,相对玉米单种,水分生产率提高1.20 kg/(mm·hm2),土地利用率提高43%,单产达10 481.5 kg/hm2,经济纯收入提高40.39%.For one year one ripe, abundant solar-thermal resources, insufficient climate and natural characteristics of a year two ripe in mountain area of southern Ningxia, efficiency study on maize interplanting soybean under the condition of all membrane covering was studied. The study showed that ecological, economic and social benefit of the planting pattems was very obvious, compared to single corn , moisture productivity increased by 1.20 kg/ （hm2·mm）,and land utilization increased by 43%. The yield was 10 481.5 kg/hm^2, and net income increased by 40.39%.
