【中文摘要】 采用串并联通气栽培法 ,研究了CO2 浓度对灰树花 (Grifolafrondosa)、灵芝 (Gano dermalucidum)、猴头菌 (Hericiumerinaceus)和草菇V35(Volvariellavolvacea)菌丝生长的影响。结果表明 ,在供氧充分、低CO2 浓度环境中 ,灰树花、草菇V35菌丝生长量最大 ,随CO2 浓度增高 ,菌丝生长量呈降低趋势 ;而相对较高的CO2 浓度能加速猴头菌和灵芝菌丝的生长。灰树花、灵芝、猴头菌、草菇V35菌丝正常生长的适宜CO2 浓度分别为 :0 .2 %～ 0 .8%、3.5%～ 11.1%、0 .4 %～ 2 .1%和 0 .3%～ 10 %。灰树花、猴头菌、草菇V35菌丝停止生长和死亡的CO2 浓度临界值近似相等 ,分别为 4 .3%、5.7%和 18.9% ;而灵芝菌丝停止生长的CO2 浓度上限临界值为18.81% ,菌丝死亡的CO2 浓度上限临界值大于 2 0 %。
【英文摘要】 The effect of different concentration of carbon dioxide on the mycelial growth of Grifola frondosa, Ganoderma lucidum, Hericium erinaceus and Volvariella volvacea was studied by employing series-parallel connection and ventilation-cultivation-method in this paper. It was proved in our experiment that at low CO 2 concentration (0.03%),the mycelial growth rate of G. frondosa and V.volvacea was the highest, but it gradually decreased with the increment of CO 2 concentration, and that the mycelial growth rate of G.lucidum and H.erinaceus was the highest at relatively higher CO 2 concentration. And the optimal CO 2 concentrations for the mycelial growth of G.frondosa, G.lucidum, H. erinaceus and V.volvacea were 0.2%～0.8%, 0.4%～2.1%, 0.2%～10% and 3.5%～11.1% resp.,while the CO 2 concentrations with irreversible lethal effect on the mycelia of G. frondosa, H. erinaceus and V.volvaeca were 4.3% 5.7% and 18.9% resp., which could hardly be distinguished from the CO 2 concentrations needed to stop...更多 their mycelial growth. But the mycelia of G.lucidum stopped growth at the CO 2 concentration of 18.8%, and the CO 2 concentration with lethal effect on its mycelia was over 20%. 还原
