中文摘要	通过大田试验,研究了施氮水平和带型配置对玉米间作豌豆产量及水分利用效率(WUE)的影响.结果表明:玉米间作豌豆具有显著的间作优势,土地当量比介于1.08~1.55之间,3:4间作模式的产量显著高于2:4间作模式,施氮能够显著提高作物的产量,而中,高施氮处理差异不显著;间作的耗水量比单作高13.66%~18.93%,3:4间作模式在中施氮处理的耗水量显著高于2:4间作模式,玉米对间作复合群体的影响大与豌豆;施氮条件下玉米间作豌豆显著提高了WUE,3:4间作模式在高施氮水平的WUE显著高于2:4间作模式,而中,高施氮处理差异不显著,2:4间作模式中玉米对复合群体的贡献大,3:4间作模式中豌豆对复合群体的贡献大
英文摘要	A field experiment was conducted to investigate the effects of nitrogen application and stripe compound indexes on yield and WUE of maize/pea intercropping systems in an oasis irrigation region. The results showed that there was a significant yield advantage in maize/pea intercropping, the limits of LER was 1.08~1.55, the yield of 3:4 type was significantly higher than that of 2:4 type. Moreover, yield of nitrogen application was significant higher than that of no nitrogen application treatment, there was no significant difference between middle and high nitrogen application;water consumption of intercropping was higher 13.66 %~18.93 % than that of monocropping, water consumption of middle nitrogen application at 3:4 type was significant higher than that of 2:4 type, water consumption of maize was higher than that of pea in maize/pea intercropping canopy;the WUE was a significantly increased in maize/pea intercropping at nitrogen application and nitrogen application was significantly higher than that of no nitrogen application, there was no significant difference between middle and high nitrogen application, contribution of maize in 2:4 maize/pea intercropping to WUE was greater than pea,in 3:4 maize/pea intercropping, contribution of pea was greater
