摘　　要：In order to find the best intercropping pattern of fresh maize and mung bean, five planting patterns, namely fresh maize monocropping, mung bean monocropping, fresh maize and mung bean intercropping at row ratios of 2∶4, 3∶3 and 4∶2 were set up, and the yields and economic benefits of these planting patterns were analyzed. The results showed that the LERs of the three intercropping patterns were all above 1, and the economic benefits of 2∶4, 3∶3 and 4∶2 fresh maize and mung bean intercropping patterns were seen an increase of 2.85%, 17.64% and 14.26% respectively compared with fresh maize monocropping and an increase of 52.06%, 73.92% and 68.93% respectively compared with mung bean monocropping.Among the three intercropping patterns, the intercropping pattern with row ratio 3∶3showed the best effect, which also derived the highest LER with greatest economic benefit.为探明鲜食玉米与绿豆最佳间作模式,设置玉米单作、绿豆单作、玉米和绿豆2∶4间作、3∶3间作、4∶2间作等5种种植模式,分析不同种植模式对作物产量及经济效益的影响。结果表明:玉米与绿豆有明显的间作优势,3种间作模式的LER均大于1,玉米与绿豆3种间作模式较玉米单作分别增效2.85%、18.13%和14.26%,较绿豆单作分别增效52.06%、74.66%和68.93%。综合来看,玉米与绿豆3:3间作的种植模式在LER、经济效益等方面为最优。
