摘　　要：在大田试验条件下,研究了玉米‖大豆间作对辽西地区作物生长和产量的影响。结果表明:间作对玉米、大豆各项生长指标均有不同程度的影响;间作模式玉米的产量及产量性状指标均高于单作模式,尤其边行1的优势更为明显;灌溉条件与雨养条件下对比发现,间作模式下玉米产量性状指标差异不显著,而单作模式下穗长、穗粒数和产量灌溉处理高于雨养处理,并达显著水平。间作种植的大豆产量较单作种植有所下降,灌溉处理的间作模式比单作模式减产15.49%,雨养处理间作模式比单产模式减产29.76%;间作模式在灌溉条件下水分利用效率高于单作模式;综合分析表明辽西地区玉米大豆间作4∶4模式是提高产量和增加效益的适宜模式。In conditions of the field experiment,Investigated the effect of maize and soybean interplanting on their growth and yield in western Liaoning province.The result showed that intercropping had different influences on growth traits of maize and soybean,and maize yield and yield character under interplanting mode was higher than the single model,especially in border row 1.Comparing irrigation with rainfed conditions,maize yield characters had no significant difference under interplanting mode;howerer,ear length,grains per ear and yield under irrigation treatment were significantly higher than rain-fed mode.Interplanting＇s soybean yield was lower than monoculture,the number in irrigation and rain-fed mode reduced 15.97% and 29.76%,respectively.Water use efficiency for interplanting was higher than single mode unedr irrigation condition.It showed that the best mode of improving yield and efficiency was 4∶4 maize and soylzean interplanting in western Liaoning province.
