中文摘要	研究了马铃薯‖大豆,玉米‖大豆以及单作条件下马铃薯,玉米,大豆的主要农艺性状和效益.结果表明:间作模式对马铃薯和玉米主要农艺性状影响不明显,大豆有效分枝数较单作分别降低了68.3%和32.1%;2种间作模式的土地当量比均大于1(LER=1.56和1.30),间作优势明显;间作模式下公顷纯收益较大豆单作分别增加了13 139.55元和10 282.56元,差异均达极显著水平(P<0.01).综合考虑投入与产出,马铃薯‖大豆间作效益最高,与3种作物单作纯收益差异极显著,值得推广
英文摘要	Intercropping is one of efficient use way for soil nutrient, water and heat resources in semi-arid area of northwest China. The aims of this study were to improve the effects of intercropping models of soybean with different crops in semi-arid land. The agronomic characteristics and benefits of different intercropping models were studied in semi-arid area of Gansu. The results showed that the major agronomic traits of soybean had no significant difference between two intercropping models of potato‖soybean and maize‖soybean, while the number of effective branches of soybean in two intercropping models decreased by 68.3% and 32.1% than monoculture of soybean, respectively, and two intercropping models of soybean with potato and maize displayed higher benefit than monoculture of soybean with net income increased by 13 139.55 and 10 282.56 yuan(RMB) per hectare, respectively, with higher land equivalent ratio from 1.56 to 1.30.So the intercropping model of potato‖soybean is a farmer-friendly way with the highest benefit for dry-land cultivation in semi-arid area of northwest China
