| Abstract: | In order to understand function mechanism and colonization dynamics of plant growth promoting rhizobacteria （PGPR）, this paper summarized species and research progress of plant growth promoting bacteria, main influence factors of microbial colonization, detection methods of colonizing microorganisms, promoting mechanism of PGPR including producing iron carrier, nitrogen fixation and phosphate-solubilizing, produce IAA etc. In conclusion, research on screening of PGPR strain and adaptability should be strengthened, and molecular biology techniques should be applied into the study of PGPR. The paper highlighted the full use of traditional culture combined with molecular biology techniques to discuss succession of Research direction in the future was analyzed and forecasted. rhizosphere microflora. |
