中文摘要	【目的】针对解决集约化栽培条件下间作密植潜力研究薄弱、生产中缺乏间作增密增产理论和实践依据的问题.【方法】在河西绿洲灌区通过大田试验,研究了低、中、高(4.50、5.25、6.00万株/hm~2)玉米密度对玉米间作豌豆群体产量及其构成因素的影响,以期为玉米间作豌豆合理密植提供理论依据.【结果】玉米间作豌豆具有明显的产量优势,低、中、高玉米密度下的间作土地当量比均大于1.2.除在中密度水平下,间作的籽粒总产量低于相应单作4.89%,其余处理均表现为间作籽粒总产量高于单作,间作生物总产量高于单作豌豆;单位面积间作玉米及间作豌豆的籽粒产量和生物产量分别平均比相应单作增加了82.03%和5.89%、37.12%和2.88%;随玉米密度的增大,间作的籽粒总产量、间作玉米和单作玉米的籽粒产量及间作玉米的生物产量均呈增大趋势.通径分析结果表明:3个产量性状对玉米籽粒产量的综合效应排序为:穗数>穗粒数>500粒质量,所以穗数对玉米增产的贡献居所有产量性状之首;4个产量性状对豌豆籽粒产量的综合效应排序为:株数>百粒质量>单株荚数>单荚粒数,说明对豌豆籽粒产量影响较大的是株数和百粒质量.【结论】综合作物的产量高低、产量性状表现及通径分析结果可得:随玉米密度的增大,间作可以显著提高主栽作物玉米的籽粒产量,进而提高间作的籽粒总产量,但会影响豌豆在间作中籽粒产量的优势,所以玉米间作豌豆较单作具有更高的容纳高密度的潜力和产量优势,且密植是提高间作产量的有效措施.
英文摘要	【Objective】 In order to provide theoretical basis for reasonable close-planting of maize/pea intercropping system and solve the problem of weak research on close-planting-intercropping potential under the intensive cultivation conditions.【Method】 A field test was conducted to investigate the effects of different planting density of maize (45 000,52 500,60 000 plant/hm~2) on yield and its component factors in the oasis region of Hexi corridor,Gansu province.【Result】 There was a significant yield advantage in intercropping system,the land equivalent ratios (LER) of different treatments was higher than 1.2.Total grain yield of intercropping was lower than that of mono-cropping by 4.89% under the medium density while total grain yield and biomass of intercropping under other treatments was markedly higher in those of mono-cropping and the total biomass reaching 82.03% and 5.89%,37.12% and 2.88%,respectively.The total grain yield in the intercropped system,yield in maize/pea intercropping and mono-cropped maize and biomass yield in intercropped maize all tended to increase with the rise of the density.Path analysis showed three comprehensive effects of yield traits on the grain yield of maize ranked as follows: spike number>grains per spike>500-grain weight,indicating that spike number contributed the most to maize yield.The comprehensive effects of four yield traits on the grain yield of pea ranked as follows: plant number>100-grain weight >pod per plant >grain per pod,showing that plant number and 100-grain weight had large effect on pea grain yield.【Conclusion】 With the increase of maize density,intercropping could significantly improve the grain yield,and then enhanced the total grain yield of intercropping,but it would affect the grain yield of the pea in the intercropping.Compared with the mono-cropping,maize/pea intercropping had a potential advantage of high density and yield and close-planting was an effective measure to improve the yield of intercropping.
