Plant growth-promoting rhizobacteria(PGPR)has the function of resisting plant diseases and promoting plantgrowth.The rhizosphere bacteria previously isolated from the rhizosphere soil of garlic in continuous cropland in JinxiangCounty of Shandong Province were studied.The results showed that the selected strains had good antagonism on the pathogensH5( Setophoma terrestris)and H9( Fusarium solani)of garlic rootrot.The strain DS7 was initially identified by thesequence analysis of the 16S rRNAgene,which belongs to the genusBacillus.The study of functional properties showed that the inhibition rate of strain Bacillussp.DS7 inhibition to H5 reached51.72%,and the inhibition rate to H9 reached42.31%.The strain DS7 carrys the abilities of producingedIAA(19.29±0)μg/mL,producing iron-producingcarrier,hydrolyzinged protein,and dissolving phosphorus-dissolving ability,but does can ’t have the ability to produce ACCdeaminase.The field inoculation test results showed that the garlic yield increased by 15.42% after inoculation with strainDS7,andthe invertase activity and urease activity of soil were higher than that of the controlsoil,and the catalase activity was lowerthan that of the control soil.In summary,the plant rhizosphere growth-promoting strain Bacillussp.DS7 has a variety offunctional properties,which can increase the yield of garlic in the field and improve the soil.It is a potential microbe fertilizer production strain.
