The Research on the Temporal and Spatial Distribution of Several Rhizosphere Microorganisms
Abstract: Rhizosphere microorganisms play an active role in the storage and release of nutrients and the decomposition of organic matter in the rhizosphere of plants. Rhizosphere microorganisms can affect plant growth and nutrient uptake by affecting the morphology and physiological characte-ristics of plant roots, and anti-microbial particles produced by some rhizosphere microorganisms can also inhibit the reproductive development of some pathogen in plant rhizospheres. However, soil microorganisms are small, large in number, difficult in isolation and identification, and complicated in soil environment conditions, which restrict the understanding of the relationship between rhizosphere microorganisms and vegetation. Therefore, in this study, five representative plants were selected and the rhizosphere soil extracts were cultivated into four different mediums, including yeast extract, pure agar, PDA, and Gause’s No.1 medium. Then, seasonal changes of biomass in each particular plant were studied by colony counting, and the similarities and differences between different plants’ microbial community structures were analyzed, trying to explain the correlation between rhizosphere microorganism number, community structure and plant types as well as environmental factors.
