　　以马铃薯与蚕豆不同间作模式为对象，研究分析了不同间作模式下马铃薯、蚕豆的光合生理参数、农艺性状等。结果表明：全膜双垄沟播种植方式下马铃薯叶片光合生理活性相对较高，鲜薯产量达35131．5 kg?hm-2，与常规露地垄作种植鲜薯产量31302．0 kg?hm-2差异显著。不同间作模式的土地当量比（LER）均大于1，全膜双垄沟播种植模式土地当量比为2．07，间作增产率达107．17％，间作优势明显。间作可实现土地、劳动力、土壤养分和水热资源的集约化利用。综合考虑投入与产出，高寒阴湿区采用全膜双垄沟播间作模式效益最高，值得推广。

The experiment was conducted to investigate photosynthetic physiological parameters ,agronomic charac-ters and land equivalent ratio (LER) of potato and broad bean ,and to compare crop output ,economic benefit and soil nutrients under different potato/broad-bean intercropping modes ,so as to provide theoretical basis and technological sup-port for highly efficient intercropping cultivation of potato in alpine humid region .The results indicated that ,under the mode with whole film covering and double ridge-furrow planting ,the photosynthetic physiological activity of potato was improved ,and the yield of fresh tubers was 35 131 .5 kg?hm-2 ,being significantly higher than that of traditional ridge planting mode (31 302 .0 kg?hm-2 ) .The LER of all intercropping modes was higher than 1 ,in which the LER of whole film covering and double ridge-furrow planting mode was 2 .07 , and the yield increase rate of intercropping was 107 .17% .Therefore ,the advantages of intercropping were remarkable ,and it was an effective way to realize intensive use of land ,labor ,soil nutrient ,water and heat resources by intercropping .Considering input and output comprehen-sively ,the economic benefit of the intercropping mode with whole film covering and double ridge-furrow planting was the highest ,and it was suggested to extend such a mode in alpine humid region .
