熟石灰添加量对平菇熟料栽培的影响

以糙皮侧耳、肺形侧耳、淡红侧耳等侧耳属的3种平菇为试材,采用在培养料中添加0%、2%、4%和6%的熟石灰对其进行熟料栽培的方法,研究熟石灰添加量对平菇菌丝生长、子实体产量及钙含量的影响,以期为平菇的生产及相关研究提供参考依据。结果表明:在栽培料中添加2%~4%的熟石灰能显著促进平菇菌丝的生长。当熟石灰添加量为2%时,秀珍菇的产量和生物效率最高,分别为198.20 g·袋^-1和104.32%;当熟石灰添加量为4%时,平菇和红平菇的产量和生物效率最高,其产量分别为180.60、241.87 g·袋^-1,生物学效率分别为95.05%、127.30%。不同熟石灰添加量栽培获得的子实体钙含量在0.13~0.30 g·kg^-1,但不呈现出规律性,熟石灰添加量对平菇子实体的钙含量影响不明显。综合各项指标表明,在平菇栽培料中添加2%~4%的熟石灰较为合适,具体添加量因品种而异,熟石灰添加量不影响平菇子实体的钙含量。

Effects of Hydrated Lime on the Cultivation of Oyster Mushroom

Three Pleurotus species,P.ostreatus,P.pulmonarius and P.djamor were cultivated in substrate containing 0%,2%,4% and 6% of hydrated lime respectively.The effect of hydrated lime addition on the mycelial growth,fruiting body yield and calcium content of oyster mushroom were explored.In order to provide reference for the production and related research of oyster mushroom.The results showed that 2%-4% hydrated lime in the substrate could significantly promote the mycelial growth of oyster mushroom,the highest yield and biological efficiency of P.pulmonarius were obtained from the substrate formula with 2% hydrated lime,which with yield and biological efficiency of 198.20 g·bag^-1 and 104.32%,the highest yield and biological efficiency of P.ostreatus and P.djamor were obtained from the substrate formula with 4% hydrated lime,their yield exhibited 180.60 g·bag^-1 and 241.87 g·bag^-1,and the biological efficiency were 95.05% and 127.30% respectively.The calcium content of fruit body obtained from different hydrated lime substrate was 0.13-0.30 g·kg^-1,but it did not show obvious trend with the increase of supplementary hydrated lime in substrate.In conclusion,it is suitable to add 2%-4% hydrated lime to the substrate of oyster mushroom,and the exact content depend on the species.The calcium content of oyster mushroom fruiting body did not affected by the level of hydrated lime in substrate.
