平菇923菌株,是1992年3月在胶东一腐朽的榆木墩上采集到的一株重达6kg的野生平菇,经分离培养、驯化而获得的优良菌株,鉴定为糙皮侧耳(Pleurotus osveats)。经两年大面积栽培试验表明,该菌株适应范围广,生长周期短,出菇较快,抗杂抗污染能力强,配套栽培技术表现性状稳定,朵大产量高,平均每墩重2～3kg,最高达24.3kg,而且耐贮运,可作为我省的当家平菇品种。 一、形态特征 (一)菌丝体 菌丝洁白、粗壮,平板培养菌落圆形,呈放射状,菌丝呈羽绒状匍匐生长,无菌膜形成。25℃恒温培养,5天即可长满试管斜面,7天菌丝开始爬壁,15天左右菌丝表面有吐水现象。 (二)子实体 子实体灰褐色,呈塔形叠生,单丛1～10kg,菌盖直径10～20cm,菌肉白色,厚0.5～1.5cm,菌褶白色,呈不规则放射状延生。菌柄短而肥
Pleurotus ostreatus strain 923, a strain of wild Pleurotus ostreatus collected at a decaying Elm pier in Jiaodong-March 1992, was isolated, cultured and acclimated. It was identified as Pleurotus osveats). After two years of large-scale cultivation experiments showed that the strain to adapt to a wide range of short growth cycle, fruiting quick, anti-hybrid anti-pollution ability, the performance of supporting cultivation techniques stable performance, large yield large, with an average weight of 2 ~ 3kg per pier , Up to 24.3kg, but also resistant to storage and transportation, can be used as the province’s mastermind mushroom varieties. First, the morphological characteristics (A) mycelium mycelium white, thick, flat culture colonies round, radial, hyphae creeping mycelium growth, sterile film formation. 25 ℃ constant temperature culture, 5 days to over-fill the tube slope, 7 days mycelium began to climb the wall, 15 days mycelial surface spit water phenomenon. (B) fruiting body fruiting body brown, was tower-shaped overlay, single bundle 1 ~ 10kg, cap diameter 10 ~ 20cm, white meat, thick 0.5 ~ 1.5cm, fold fold white, showed irregular radial extension. Stipe short and fat
