肉桂加工剩余物木屑对赤芝生长的影响

Effects of sawdust from cinnamon processing residue on the growth of Ganoderma lucidum

以肉桂(Cinnamomum cassia Presl)加工桂皮后的剩余物木屑为原料,研究其对赤芝(Ganoderma lucidum)生长的影响。结果表明,赤芝生长不同阶段培养基中添加肉桂加工剩余物木屑对赤芝生长具有一定的促进作用。其中,母种培养基中添加肉桂加工剩余物木屑75~150 g/L,菌丝生长速度可达8.2~8.4 mm/d,菌种贮藏时间可延长至9个月;原种、栽培种培养基中分别添加200~300 g/kg、300~500 g/kg的肉桂加工剩余物木屑,菌丝生长速度分别达8.4、9.3 mm/d,明显高于对照。出芝袋中添加肉桂加工剩余物木屑450~600 g/kg、泥碳土75~100 g/kg,可使生物学转化率提高到66%~72%。

The effects of sawdust from cinnamon processing residue on the growth of Ganoderma lucidum were studied.The results showed that the growth rate of Ganoderma lucidum could be promoted by adding sawdust from cinnamon residue sawdust in different growth stages.The growth rate of mycelia could reach to 8.2~8.4 mm/d and the storage time of strain could be extended to 9 months when adding 75~150 g/L of cinnamon processing residue sawdust to the gar medium.The growth rate of mycelia could reach 8.4 mm/d and 9.3 mm/d when adding 200~300 g/kg and 300~500 g/kg of cinnamon processing residue sawdust to the primary seed medium and culture medium respectively,obvious higher than that of the control.Adding 450~600 g/kg of cinnamon processing residues sawdust and 75~100 g/kg of clay soil to medium for fruiting of Ganoderma lucidum could increase the biological conversion rate to 66%~72%.
