摘　　要：玉米与穿山龙不同间作方式的试验结果表明:间作对玉米产量影响不显著,穿山龙产量略有下降,间作的经济效益明显高于清种玉米;玉米株间作穿山龙较玉米垄间作穿山龙更有利。The intercropping patterns of Dioscorea nipponica Makino and Maize were investigated to find which intercropping pattern could have higher potential of benefit. The results showed that maize yield changed little with intercropping, and the yield of Dioscorea nipponica Makino decreased slightly. The total benefit of intercropping was improved obviously compared with that of single cropping. Moreover,interplanting in a ridge had more benefit than ridge intercropping.
