Abstract: The characters of peat，vermiculate，perlite，saw dust，sand and other growing media are briefly introduced in this paper．The effects of the above media on growth and development of horticultural crops，on colonization and function of arbuscular mycorrhizal fungi(AMF)，and effects of AMF fungi on growth，yield and quality of horticultural crops grown in different growing media are also discussed．The mixed media with different proportional media showed favorite characters and benefited the plant growth．For example，the colonization percentage of Glomus mosseae on watermelon grown in No．7 mixed media made of peat，vermiculate，and sand was 39．9％ ，while that in No．1 was 14．8％ ，the growth of the plant grown in the former was 1．5～3 times greater than the contro1．The mixed media are very efficient in the production of vegetables grown in soilless media and should be more widely used in the near future．
