摘　　要：为筛选可以施于烟苗根区的生物有机肥,采用盆栽试验研究了不同生物有机肥施于根区对烤烟根系形态、根系生理特性及干物质的影响。结果表明,生物有机肥施于根区,可增加烤烟根系长度、体积、直径和分枝数,提高烤烟根系活力,增加烤烟干物质量,以三饼合一生物有机肥对烤烟的促生效果最好。三饼合一生物有机肥、烟秸生物有机肥、中烟多效生物有机肥可以做基肥施于根区。凹凸棒复合微生物有机肥不能做基肥施于根区。In order to select bio-organic fertilizer applied to tobacco plant root-zone,a pot experiment was conducted to study the effect of different bio-organic fertilizers applied to flue-cured tobacco root-zone on root morphology,root physiological characteristics and dry biomass of roots.The results showed that bio-organic fertilizers applied to root-zone could promote root length,root volume,root diameter,root branching number,improve root activity,increase dry biomass of roots.The“bio-organic fertilizer combined with3oil cake”was found to have the best effects of accelerating tobacco root growth.“Bio-organic fertilizer combined with3oil cake”,“bio-organic fertilizer by tobacco straw fermentation”and“zhong-yan multi-effect bio-organic fertilizer”could be applied to flue-cured tobacco root-zone,while“embossed cudgel ore bio-organic fertilizer”could not be used for flue-cured tobacco root-zone application.
