Support for the culture of mushrooms promoting mycelial growth and the development of the carpophores and process for producing it

摘要

Support capable of enhancing mushroom spawn growth and carpophore development, and containing an inert, porous granular substrate, such as expanded perlite, and a nutrient phase conveying, in particular, those chemical elements essential for spawn growth and carpophore development. The inert porous substate is in a virtually anhydrous state, has a relative density less than approximately 0.2, a particle size of 2-5 mm, and a volume void ratio of 20-40%. The invention also provides a method of obtaining said substrate.
