摘　　要：为研究适合东北黑土区玉米大豆间作行比,促进玉米大豆间作模式推广应用,本研究以玉米大豆间作系统为主要研究对象,设置玉米单作(M)、大豆单作(S)、玉米大豆行比2∶4间作(M2S4)、玉米大豆行比4∶4间作(M4S4)和玉米大豆行比4∶6间作(M4S6)处理,分析不同间作行比对大豆株高及干物质积累、光合特性相关指标、产量及经济产值分析的影响。结果表明:间作显著增加了大豆株高,降低了干物质量,同时,随着玉米条带数的降低及大豆条带数的增加,光合参数Gs和Tr与单作处理之间呈显著性差异,而Ci则呈现相反的变化趋势。4∶4间作行比(M4S4)处理具有较好的间作优势,土地当量比为1.26,在考虑了政府补贴后,间作复合经济产值显著高于各单作处理,其中,M4S4处理最具有增收潜力。综上,M4S4模式为东北黑土区最佳玉米大豆间作配置方式。In order to study the suitable row ratio of maize-soybean intercropping in the black soil region of northeast China and promote the extension of maize-soybean intercropping pattern, this study took the maize and soybean intercropping system as the main research object, and set the planting modes of maize monocropping(M), soybean monocropping(S), maize-soybean row ratio 2∶4 intercropping(M2 S4), maize-soybean row ratio 4∶4 intercropping(M4 S4) and maize-soybean row ratio 4∶6 intercropping(M4 S6). The effects of photosynthetic characteristics, dry matter accumulation, yield and economic value of soybean under different intercropping ratios were analyzed. The results showed that with the decrease of maize band number and the increase of soybean band number in intercropping, the Gs and Tr were significantly different from those in monoculture, while the Ci showed an opposite trend. The treatment with 4∶4 intercropping ratio(M4 S4) had better intercropping advantages, and the land equivalent ratio was 1.26. After considering the local government subsidies, the compound economic output value of intercropping was significantly higher than that of the single cropping treatments, among which M4 S4 treatment had the most potential of increasing income. To sum up, M4 S4 is the best corn-soybean intercropping pattern in the black soil region of northeast China.
