Because of the nature and nutrients，straw and sawdust have substantial distinction，and the black fungus that is typical wood rot fungi and rot fungus straw which is good at utilizing grass also have essential differences on biological characteristics.So，using a single straw instead of sawdust to cultivate black fungus has not reached the ideal effect，it’s difficult to replace wood.I learned development experience that cultivating instead of wood log and the application technology in successful way for 20 years，taking the domestication and breeding new suitable straw growth black fungus varieties and imitation sawdust nutrition structure development ideas by adding a small amount of different crops straw wood，and gradually summed up the successful experience of cultivation black fungus using crop straw instead of sawdust.
