A method for hydroponic cultivation of crops by using mycorrhizal fungi and their partner bacteria includes growing a partner plant between rows of the crops, and inoculating a mycorrhizal fungal strain and a partner bacterial strain to infect the partner plant or the crop with the mycorrhizal fungal strain, wherein the partner bacterial strain is compatible and coexists with the mycorrhizal fungal strain, and the partner plant facilitates growth of the mycorrhizal fungal strain and the partner bacterial strain.
