Abstract：Taking tillering onion and tomato as material，this paper studied the effects of concomitant
tillering onion on tomato rhizosphere soil bacterial and fungal community constitution and structure using highthroughput
sequencing．Results showed that comparing with tomato monoculture，concomitant treatment
with tillering onion could change the bacterial and fungal community constitution in tomato rhizosphere soil．
Proteobacteria，Bacteroidetes，Actinobacteria，Acidobacteria，Firmicutes，Planctomycetes，Chloroflexi
were advantage bacteriophyta．Ascomycota，Zygomycota，and Basidiomycota were dominant fungal
phylum．At class level，the treatment of concomitant tillerng onion could significantly enhance the relative
abundance of Alphaproteobacteria with beneficial potential，while reduced that of Sordariomycete and
Eurotiomycetes．At the order level，concomitant tillering onion treatment could significantly enhance the
relative abundance of Sphingomonadales and Propionibacteriales，while reduce that of Microascales，
Onygenales and Xylariales．At the family level，concomitant tillering onion treatment could significantly
enhance the relative abundance of Nocardioidaceae，Microbacteriaceae，Sphingomonadaceae，Blrii41 and
Lasiosphaeriaceae，while reduce that of Microascaceae and Onygenaceae．At the genus level，concomitant
tillering onion treatment could significantly reduce the relative abundance of fake allescheria with pathopolesis
potential—Pseudallescheria，Kernia and Wardomyces．However，there was no significant effect on
rhizosphere soil bacterial，fungal community structure and biodiversity．
