Abstract:
Objective To study the amount of rhizospheric microorganisms and soil enzyme activity influenced by Paridis Rhizoma in different locations and of different strains. Methods The amount of rhizospheric microorganisms, soil enzyme activity and their correlation were researched through field survey and collection of rhizospheric soil in Paridis Rhizoma cultivated in Three Gorges Reservoir Region and by microbial dilution plate culture method. Results The amount of rhizospheric microorganisms in Paridis Rhizoma from different habitats showed significant differences. The dominant species in soil microflora was bacteria; the second one was actinomycetes; the fewest one was fungus. The variation trend of the amount of rhizospheric microorganisms was not consistent with the variation trend of rhizospheric microorganisms diversity index. The activity of soil phosphatase, invertase and pepsin in Paridis Rhizoma from different habitats varied. The correlation analysis showed that the correlation between the soil enzyme activity and the amount of rhizospheric microorganisms existed. Conclusion Choosing the suitable strains and habitats of Paridis Rhizoma is beneficial to enhancing the amount of rhizospheric microorganisms and soil enzyme activity, which can create good micro-ecological environment for growth and cultivation of Paridis Rhizoma.
