The invention discloses a production method for high-density pure arbuscular mycorrhizal fungal spore, which belongs to the technical field of microorganism culturing, and comprises the following technical steps of: 1) culturing carrot root tissues converted from agrobacterium rhizogenes plasmid DNA; 2) culturing the carrot root tissues converted from agrobacterium rhizogenes plasmid DNA and glomus intraradices together in an improved synthetic culture medium; 3) taking a culture containing the root, hypha and spore infected by the arbuscular mycorrhizal fungus and transplanting the culture toa special culture box for culturing; 4) collecting the spore and mycelium; and 5) storing the arbuscular mycorrhizal fungal spore. Compared with the prior art, the production method for high-densitypure arbuscular mycorrhizal fungal spore has the advantages that: 1, the culture medium is an asepsis environment with low cost, which not only can meet the growing of a host plant, but also is suitable for the growing of AM epiphyte; 2, the nutrition requirements for the growing of the host plant are low and the host plant can grow and be cultured on the synthetic culture medium; 3, the spore cultured by the method is a non-pollution pure culture; and 4, the produced spore is stored in liquids and the activity can be maintained by above 90 percent.
