摘　　要：在盆栽实验条件下通过生物接种技术 ,对豆科固氮树木刺槐进行联合共生体的人工构建 ,定量研究了VA菌根真菌、外生菌根真菌、根瘤菌不同组合情况下对刺槐生长的促进作用并对 3者之间的相互关系进行了探讨。研究表明外生菌根菌与内生菌根菌两者之间的混接具有增效作用 ;菌根菌与根瘤菌之间存在着协同增效作用。促进植株生长的最佳接菌组合是根瘤菌 ) 36 6 ) +VAR +毛边华锈伞 (H .mesophaseum 870 191)With biological inoculation technology, experiment was conducted in pot cultures to study the effect of dual inoculation of \%Rhizobium\% and mycorrhizal fungi. The result showed the stimulation on the growth of the host plant of mycorrhizae or \%Rhizobium\% and the more obviously improved effects on the growth of \%Robinia pseudoacacia\% than the treatment inoculated singly by VAM or Ectomycorrhiza. It also showed the corelation of \%Rhizobium\% and mycorrhizae. The best treatment of better growth of plant was inoculating VAR+ Rhizobium (336)+ \%H.mesophaseum\% (870191).
