中文摘要:通过探究氮肥减施对玉米间作箭筈豌豆种间关系的影响,为进一步发挥禾豆间作优势提供理论依据。2017年在甘肃省武威市甘肃农业大学绿洲农业综合试验站进行试验,以玉米、箭筈豌豆为试验对象,设单作箭筈豌豆(V)、单作玉米(M)、玉米间作箭筈豌豆(M/V)3个种植模式和不施氮(N0,0 kg·hm-2 )、减量施氮(N1,240 kg·hm-2 )、传统施氮(N2,300 kg·hm-2 )3个施氮水平,探究河西绿洲灌区减量施氮对玉米间作箭筈豌豆种间关系及产量的影响。结果表明,箭筈豌豆干物质积累量间作较单作增加43.0%,减量施氮比传统施氮增加10.9%;玉米干物质积累量间作较单作增加26.7%,减量施氮比传统施氮增加8.5%;共生期内箭筈豌豆相对于玉米的竞争比率始终大于1,表明箭筈豌豆的种间竞争力强于玉米,且减量施氮能增强种间竞争;箭筈豌豆收获后间作和单作玉米生长速率比在不同施氮水平下均大于1,表明间作玉米有明显的恢复效应。箭筈豌豆产量间作较单作增加37.7%,减量施氮与传统施氮无显著差异;玉米产量间作较单作增加3.4%,且间作模式下减量施氮比传统施氮增加4.0%;各间作处理土地当量比无显著差异且均大于1,说明具有增产优势。因此,玉米间作箭筈豌豆氮肥减施20%可通过调控种间关系进一步挖掘间作增产潜力,是绿洲灌区玉米生产的可行措施。

Effect of Reduced Nitrogen Fertilization on Interspecific Relationship and Yield Performance of Maize-vetch Intercropping
Abstract:The interspecific relationship between Vicia sativa (common vetch)in maize intercropping was revealed,providing a theoretical foundation for further exploiting the advantages of intercropping with cereals and legume.This study was conducted in 2017 at the Oasis Agriculture Comprehensive Experimental Station of Gansu Agricultural University in Wuwei city,Gansu province. Maize and Vicia sativa were selected as the experimental subjects.Three planting patterns were set up:monocropping of Vicia sativa (V),monocropping of maize (M),and intercropping of maize and Vicia sativa (M/V).Three nitrogen application levels were considered:no nitrogen application (N0,0 kg·hm-2 ),reduced nitrogen application (N1,240 kg·hm-2),and traditional nitrogen application (N2,300 kg·hm-2 ).The objective was to explore the effect of reduced nitrogen application in the Hexi Oasis irrigation area on the interspecific relationship and yield of maize intercropped with Vicia sativa.The results showed that the dry matter accumulation of Vicia sativa increased by 43.0% compared with monocropping,and by 10.9% under reduced nitrogen fertilization compared with conventional nitrogen fertilization.The dry matter accumulation of maize increased by 26.7% compared with monoculture and by 8.5% under reduced nitrogen application compared with conventional nitrogen application.Through the symbiotic period,the competition ratio between Vicia sativa and maize consistently remained greater than 1.The growth ratios of intercropped and monocultured maize were greater than 1 following the harvest of Vicia sativa under various nitrogen application levels,indicating that intercropped maize exhibited a significant recovery effect.The yield of Vicia sativa intercropping was 37.7% higher than that of monocropping,and there was no significant difference under the N application level.The intercropping maize yield increased by 3.4% compared with the monoculture and by 4.0% under reduced nitrogen application compared with conventional nitrogen application.There was no significant difference in the land equivalent ratio of each intercropping treatment; all were greater than 1,indicating an advantage of increasing production.Therefore,a 20% reduction in nitrogen fertilization of Vicia sativa can further explore the potential of intercropping by regulating the inter-specific relationship,which is a feasible measure for maize production in the Oasis irrigated area.
