<p>A process for producing a substance inoculated with a VA mycorrhizal fungus, which comprises cultivating a plant infected with a VA mycorrhizal fungus belonging to the genus Gigaspora by using a base material comprising calcined Akadama soil or a mixture thereof with calcined attapulgite to thereby proliferate the VA mycorrhizal fungus. This process serves to prevent contamination with indigenous VA mycorrhizal fungi, pathogenic bacteria and the like and efficiently proliferate a VA mycorrhizal fungus belonging to the genus Gigaspora used as a pure seed fungus. The invention serves to prepare a substance inoculated with a VA mycorrhizal fungus, which is easy to handle and has a high spore density, at a low lost. Furthermore, the invention makes it possible to commercialize, as such, the base material for proliferating a VA mycorrhizal fungus, so that a troublesome step of spore separation can be dispensed with and the operation can be simplified.</p> |
