Abstract: In order to provide reference for soil problems such as continuous cropping obstacles and soil borne disease, the experiment was carried out with the rhizosphere soil of Panax notoginseng at different plant ages as material, the changes of the number of bacteria, fungi, actinomycetes and their enzyme activities were determined. The results show that with the increase of the planted age, the number of rhizosphere bacteria, fungi and actinomyces were reduced, with the most quantity of soil microbial in CK, the second in 1 year-old soil and the minimum in 3 year-old soil. . From April to December, the rhizosphere bacteria of 1 year-old were reduced by 23%-74%, the fungi were decreased by 6%-37.5%, and the actinomyces by 12%- 66.7%. The rhizosphere bacteria of 2 year-old were decreased by 18%-80.7% , the fungi were reduced by 50%-60% and the actinomyces by 32%-79%; The rhizosphere bacteria of 1 year-old were reduced by 37%-87.9%, the fungi were reduced by 50%-75% and the actinomyces by 33%-52%;while the catalase, urease, phosphatase activity were decreased with the order that CK (never planted)soil enzyme activity ranked the first,the1year the second, and 3 years old the minimum. Therefore, the plant age of Panax notoginseng had a great influence on its rhizosphere microorganisms and enzyme activities. The amount of Panax notoginseng rhizosphere microorganisms decreases with the increase of the planted age, and the neutral phosphatase, urease and catalase enzymes activity decreased.

Key words: Panax notoginseng, rhizosphere soil, microbial community structure, enzyme activity
