摘　　要：肥料施用不当会导致大豆贪青晚熟、倒伏、病虫害加重及肥料和产量效益下降。为提高肥料效益,充分发挥大豆单产和品质潜力,采用单因素试验设计,通过大田研究了7种施肥模式F1(基施3000 kg/hm^(2)有机肥+300 kg/hm^(2)化肥)、F2(基施3000 kg/hm^(2)有机肥+150 kg/hm^(2)化肥+追施150 kg/hm^(2)化肥)、F3(基施3000 kg/hm^(2)有机肥+225 kg/hm^(2)化肥+追施75 kg/hm^(2)化肥)、F4(基施1500 kg/hm^(2)有机肥+75 kg/hm^(2)化肥+追施225 kg/hm^(2)化肥)、F5(基施300 kg/hm^(2)化肥)、F6(基施150 kg/hm^(2)化肥+追施150 kg/hm^(2)化肥)和F7(基施225 kg/hm^(2)化肥+追施75 kg/hm^(2)化肥)对大豆生长发育、光合、产量和品质的影响。结果表明,增施有机肥相比单施化肥可显著提高大豆根干质量,单施化肥以基追比3∶1最有利于增加根干质量。有机肥与化肥配施单株鲜叶质量、干叶质量、鲜茎质量、干茎质量及单株鲜质量和干质量高于单施化肥,单施化肥各处理间上述指标差异不显著。有机肥与化肥配施提高了大豆结荚期和鼓粒期单株叶片数和叶面积指数,不施有机肥条件下化肥基追比3∶1有利于提高大豆叶片数和叶面积指数。有机肥与化肥配施比单施化肥开花期和鼓粒期的光合速率分别提高了16.69%~21.66%和14.99%~30.66%,化肥基追比不合理或减少有机肥用量会降低大豆生育中后期叶绿素含量和光合速率。增施有机肥可提高大豆产量和籽粒粗蛋白含量,而降低粗脂肪含量,单施化肥以基追比3∶1最利于增产。综合得出,有机肥与化肥配施在改善大豆生长发育、光合及产量和品质方面明显优于单施化肥,单施化肥以基追比3∶1表现较优。Improper application of soybean fertilizer can lead to late ripening,lodging,worsening of diseases and pests,and a decrease in fertilizer and yield benefits,to improve fertilizer efficiency and fully tap into the potential of soybean yield and quality,therefore,this article investigates the effects of seven fertilization modes F1(basic application of 3000 kg/ha organic fertilizer+300 kg/ha chemical fertilizer),F2(basic application of 3000 kg/ha organic fertilizer+150 kg/ha chemical fertilizer+topdressing 150 kg/ha chemical fertilizer),F3(basic application of 3000 kg/ha organic fertilizer+225 kg/ha chemical fertilizer+topdressing 75 kg/ha chemical fertilizer),F4(basic application of 1500 kg/ha organic fertilizer+75 kg/ha chemical fertilizer+topdressing 225 kg/ha chemical fertilizer),F5(basic application of 300 kg/ha chemical fertilizer),F6(basic application of 150 kg/ha chemical fertilizer+topdressing 150 kg/ha chemical fertilizer)and F7(basic application of 225 kg/ha chemical fertilizer+topdressing 75 kg/ha chemical fertilizer)on soybean growth,development,photosynthesis,yield,and quality through field experiments using a single factor experimental design.The results showed that increasing the application of organic fertilizer significantly enhanced the dry weight of soybean roots when compared to applying chemical fertilizer alone,applying chemical fertilizer alone with a base to top dressing ratio of 3∶1 was the most beneficial for increasing root dry weight.The combination of organic fertilizer and chemical fertilizer resulted in higher fresh leaf weight,dry leaf weight,fresh stem weight,dry stem weight per plant,as well as higher fresh weight and dry weight per plant when compared to single application of chemical fertilizer,and there were no significant differences in the above indicators among the treatments treated with single application of chemical fertilizer.The combination of organic fertilizer and chemical fertilizer increased the number of leaves per plant and leaf area index of soybean at pod bear
