工厂化栽培白灵菇配方筛选试验

对白灵菇在6种栽培配方上菌丝生长速度及工厂化出菇情况进行了研究。结果表明:在不同配方上,白灵菇菌丝生长速度、生长势、子实体形状和生物学效率均存在差异。配方⑤(棉籽壳53%,玉米芯33%,麸皮6%,玉米面6%,石灰1%,石膏1%)菌丝生长速度最快,平均为4.19mm/d,但产量较低,平均生物学效率仅为27.30%;配方③(棉籽壳47%,玉米芯29%,麸皮16%,玉米面6%,石灰1%,石膏1%)菌丝生长速度适中,产量最高,平均生物学效率为36.47%,一级菇成品率达88.74%。综合试验结果,配方③适宜在工厂化白灵菇生产中应用。

Screening of Culture Medium for Industrial Cultivation of Pleurotus nebrodensis

The mycelia growth speed and industrial fruiting process of Pleurotus nebrodensis grown on six culture media were compared.The results showed that on different culture medium,the mycelia growth speed,growth potential,shape of fruit body and biology efficiency of P.nebrodensis were discrepancy.On the fifth culture medium,mycelia of P.nebrodensis grow fast,the average growth speed was 4.19 mm/d,but the total production was low,the average biology efficiency was only 27.30%;on the third culture medium,the mycelia grow not so fast,but the total production was as high as 36.47%,the rate of Class A mushroom arrived 88.74%.In conclusion,the third culture medium(cotton seed hulls,47%;corn cob,29%;bran,16%;corn flour,6%,lime,1%;plaster,1%) was optimal medium for the industrial cultivation of P.nebrodensis.
