Abstract:: To screen out the most suitable C/N cultivation material of Pleurotus geesteranus growth，the effect of different C/N cultivation material on mycelial growth，fruitbody yield and biological efficiency of Pleurotus geesteranus were studied.The results showed that the mycelial and fruitbody of Pleurotus geesteranus could grow in every treatment，but it had difference.Mycelial of Pleurotus geesteranus grow rapidly,vigorous,pure white and bushy when the C/N were from 67∶1 to 69∶1，the biological efficiency was increasing step by step when C/N was increasing from 52∶1 to 69∶1，the biological efficiency was the highest when the C/N was 69∶1.Then the biological efficiency was depressing gradually over 69∶1.Comprehensive consideration of the vegetative growth and biological efficiency two factors，the optimum C/N of Pleurotus geesteranus was from 68∶1 to 69∶1.
