Abstract: The mycorrhizal infection rate, survival rate, growth and chlorophyll content of Pinus elliottii seedlings inoculated with Boletus edulis, Rhizopogen luteous and double inoculated with Be and RI were investigated. A plot comparative test was used in the experiment.The results indicated that the ectomycorrhizal fungi could improve the mycorrhizal infection rate, survival rate and increase the content of chlorophyll in Pinus elliottii seedlings. It had a significant growth promoting effect on pine seedlings. The quantity of rhizosphere microrganisms in P. elliottii seedlings was also determined in this study. Results showed that the number of rhizosphere bacteria significantly increased, rhizosphere fungi significantly reduced, and the quantity of actinomyces increased obviously. The technology of ectomycorrhizal fungal inoculation provided theoretical basis and practical guidance for the pine afforestation.
