Abstract: In recent years, continuous cropping has been a threat to the yield and quality of crop. Researches proved that Arbuscular mycorrhizal (AM) fungi and crop roots formed symbiosis mycorrhiza, and it resisted against the external aggression of environment by secreting secondary metabolites. For detecting the function and mechanism of action on AM fungi in crops regulating secondary metabolites, the effects of AM fungi on the types of secondary metabolites and contents were summarized. The mechanism of AM fungi in ecological defense continuous cropping was concluded, including secondary metabolites inducing signaling substances forming, allelopathic autotoxicity of continuous cropping crops, and AM fungi promoting the increase of secondary metabolites and relieve continuous cropping obstacle. At last, current problems in the research were pointed out and future research direction was proposed.
