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氮肥利用率的影响。结果表明:玉米间作豌豆具有显著的间作优势,3∶4间作模式的产量显著高于2∶4间作,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;间作显著提高作物吸氮量,3∶4间作模式在中施氮处理的吸氮量显著高于2∶4间作模式;间作显著提高了氮肥利用率,3∶4间作模式的氮肥利用率显著高于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 in oasis irrigation region of northwestern China to study the effects of different nitrogen applications and stripe compounds on yield and nitrogen use efficiencies in maize and pea intercropping system. The results showed that there was a significant yield advantage in intercropping system. The yield of 3: 4 strip type was significantly higher than 2: 4 strip type. Moreover, compared to no nitrogen application treatments, applying N fertilizer had significant increased the yield, the differences between middle and high nitrogen levels was not significant; Total nitrogen uptakes of intercropping were significantly higher than that of monoculture. Total nitrogen uptakes of middle nitrogen treatment at 3: 4 strip type was significantly higher than of 2: 4 strip type; The nitrogen use efficiency was significant increased in inter-cropping systems at nitrogen treatments and nitrogen treatments were significantly higher than that of no nitrogen treatments. There was no significant differences between middle and high nitrogen levels; Maize had more contribution to intercropping system in 2: 4 strip type while pea had more contribution in 3: 4 strip type.
