Abstract: Abstract：[Objective] The aim of our study was to investigate the effects of two different soil amendments on bacterial community structures, total number of bacteria and bacterial diversity of strawberry planting soil. [Method] The soil samples were selected from two strawberry ecological farms in Beijing, treated with two different commercial soil amendments namely effective microorganisms (EM) agent and Kaoshanduoba agent before sowing. And the bacterial communities were analyzed using high-throughput sequencing method. [Result] The results indicated that two soil amendments increased the total number of bacteria, altered the structure of soil bacteria, and meanwhile changed the composition of the bacterial community. [Conclusion] Our study demonstrated that soil amendments could increase total bacteria number, change planting soil bacteria diversity and structure, and have the huge potential to promote plant growing.
