【中文摘要】 采用串并聯(lián)通氣栽培法 ,研究了CO2 濃度對(duì)灰樹(shù)花 (Grifolafrondosa)、靈芝 (Gano dermalucidum)、猴頭菌 (Hericiumerinaceus)和草菇V35(Volvariellavolvacea)菌絲生長(zhǎng)的影響。結(jié)果表明 ,在供氧充分、低CO2 濃度環(huán)境中 ,灰樹(shù)花、草菇V35菌絲生長(zhǎng)量最大 ,隨CO2 濃度增高 ,菌絲生長(zhǎng)量呈降低趨勢(shì) ;而相對(duì)較高的CO2 濃度能加速猴頭菌和靈芝菌絲的生長(zhǎng)。灰樹(shù)花、靈芝、猴頭菌、草菇V35菌絲正常生長(zhǎng)的適宜CO2 濃度分別為 :0 .2 %～ 0 .8%、3.5%～ 11.1%、0 .4 %～ 2 .1%和 0 .3%～ 10 %?；覙?shù)花、猴頭菌、草菇V35菌絲停止生長(zhǎng)和死亡的CO2 濃度臨界值近似相等 ,分別為 4 .3%、5.7%和 18.9% ;而靈芝菌絲停止生長(zhǎng)的CO2 濃度上限臨界值為18.81% ,菌絲死亡的CO2 濃度上限臨界值大于 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%. 還原
