Abstract:Metal ions played an important role in the growth and development of edible fungi.Appropriate concentration of metal ions could promote the growth and development of edible fungi.Excessive use of metal ions and excessive enrichment in the natural growth process of edible fungi would cause heavy metal pollution of edible fungi.In this paper，the effects of metal ions on mycelial growth，extracellular enzyme secretion，nutritional value and functional active ingredient of edible fungi were reviewed，the enrichment of metal ions in fruiting bodies of edible fungi was analyzed.In order to provide reference for making full use of metal ions in the cultivation process of edible fungi.So as to provide reference basis for making full use of metal ions in the process of edible fungi cultivation.
