PDA与沼液不同配比对5种食用菌菌丝生长的影响

摘要

为筛选出马铃薯葡萄糖琼脂培养基(PDA)与沼液配比培养食用菌的适宜培养基组合,选用PDA与沼液按一定体积比例(10∶0、9∶1、7∶3、5∶5、3∶7)配比作食用菌母种培养基,进行杏鲍菇、白灵菇、茶树菇、香菇和平菇5种食用菌母种培养基筛选试验.结果表明:PDA与沼液配比为10∶0、9∶1、5∶5、3∶7、7∶3时分别适宜香菇、平菇、杏鲍菇、杨树姑和白灵菇菌丝的生长,平均生长速度分别为8.59 mm/d、17.28 mm/d、12.10mm/d、11.04 mm/d和14.71 mm/d.%Five edible mushrooms of Lentinus edodes,Pleurotus ostreatus,Pleurotus eryngii,Agrocybe aegerita and Pleurotus nebrodensis were cultured on potato dextrose agar medium (PDA) and biogas slurry mixed media with different volume proportion (10 ∶ 0,9 ∶ 1;7 ∶ 3,5 ∶ 5 and 3 ∶ 7) to screen the optimum proportion combination of PDA and biogas slurry for culture of edible mushrooms.Results:The PDA and biogas slurry mixed medium with volume proportion of 10 ∶ 1,9 ∶ 1,5 ∶ 5,3 ∶ 7 and 7 ∶ 3 is suitable for mycelial growth of L.edodes,P.ostreatus,P.eryngii,A.aegerita and P.nebrodensis respectively and their daily mean growth rate is 8.59 mm/d,17.28 mm/d,12.10 mm/d,11.04 mm/d and 14.71 mm/d separately.
