| 摘 要： | 2004—2005年在山东泰安研究了施氮量与种植方式对玉米和花生产量、生物量、氮磷吸收与利用以及蛋白质产量的影响。结果表明, 与单作相比, 玉米-花生间作显著提高了玉米产量和氮、磷吸收量, 但降低了花生产量和氮吸收量。2行玉米4行花生间作模式(2∶4间作模式)的产量、生物量、蛋白质产量、氮磷吸收量以及氮磷吸收利用效率均高于2行玉米8行花生间作模式(2∶8间作模式); 2∶4间作模式的氮、磷吸收效率均显著高于单作模式, 土地当量比(LER)和蛋白质土地当量比(PLER)均大于1, 土地利用率提高8%~17%, 间作优势明显。与不施氮处理相比, 施氮处理显著提高间作玉米产量, 间作花生增产不显著, 促进玉米-花生间作体系氮、磷积累, 提高了氮、磷吸收总量及磷吸收利用效率, 从而显著提高了间作体系的产量和蛋白质产量, 间作优势却随施氮量的增加而降低。

| Abstract: | A field experiment was carried out for revealing the effects of nitrogen application and planting pattern on yield, biomass, N and P absorption, protein yield of maize (Zea mays L.)-peanut (Arachis hypogaea L.) intercropping system in 2004 and 2005. The results showed that the yield, N and P absorption of intercropping maize increased significantly, however, the yield and N absorption of intercropping peanut was reduced in the intercropping system, compared with monocropping maize or peanut respectively. The 2-row maize and 4-row peanut pattern (2:4 pattern) showed higher (P<0.01) values than the 2-row maize and 8-row peanut pattern (2:8 pattern) in yield, biomass, protein yield, N and P fertilizer absorption efficiencies, N and P use efficiencies of intercropping system, and higher (P<0.01) values than the two monocropping systems in N and P absorption efficiencies. Both the land equivalent ratio for yield (LER) and land equivalent ratio for protein yield (PLER) in 2:4 pattern were above 1, and the land use ratio enhanced by 8%–17%, implying obvious intercropping dominance. Compared with zero N application, nitrogen fertilizer increased yield and protein yield of maize and peanut in the intercropping system by promoting the accumulation and absorption of N and P, enhancing P use efficiency, but the intercropping dominance was weakened with the increase of nitrogen fertilizer. |
