摘　　要：在人工控制环境条件下研究了CO_2浓度对金针菇(Flammulina velutipes)生长发育的影响结果表明,金针菇菌丝正常生长所要求的适宜CO_2浓度为261.7～2930.5μmol/L;金针菇子实体原基形成随CO_2浓度升高明显受到抑制,所要求的适宜CO_2浓度范围为12.3～60μmol/L;菇蕾形成后为获得优质高产金针菇,应提高环境内CO_2浓度,并控制在210～600μmol/L范围内。The effects of different concentrations of CO2 on the growth and development of Flammulina velutipes are studied by controlling environmental conditions. It is shown that the optimal CO2 concentration for the mycelial growth is 261.7 - 2930. 5/umol/L, and the primordium formation of Flammulina velutipes is significantly inhibited by the increment of CO2 concentration,the optimal CO2 concentration of primordium formation is 12.3~60pmol/L. For attaining excellent quality fruit of Flammulina velutipes , the range of CO2 concentration in environment is 210 ~ 600umol/L after fruit-body formation.
