榆黄蘑(Pleurotus citrinopleatus Si-ng.)是北方著名食菌,已人工栽培。为不断提高栽培榆黄蘑的产量和品质,对其子实体的形成与孢子散布进行初步研究。材料与方法供试菌株系本所自长白山林区分离的菌株。采用瓶栽法,培养料取阔叶树木屑4份,麦麸1份(按重量比)充分混匀,加水适量(加干料重的100-160％的清水),装罐头瓶,每瓶约装湿料6两,加压灭菌(15磅,2小时)接种后置于24±2℃条件下培养,约经3周左右,观察原基形成与子实体形态变化。
Pleurotus citrinopleatus Si-ng. Is a famous northern bacteria, has been cultivated. In order to continuously improve the yield and quality of cultivated Ulmus Pumila, the formation and distribution of its fruiting bodies were preliminarily studied. MATERIALS AND METHODS The test strains were strains isolated from Changbaishan forest. The bottle planting method was used to cultivate and feed 4 parts of broadleaf tree chips and 1 part of wheat bran (in terms of weight ratio), mix well, add appropriate amount of water (100-160% Wet material 6 two, autoclaving (15 pounds, 2 hours) after inoculation at 24 ± 2 ℃ under the conditions of culture, about 3 weeks to observe the formation of primordial and fruiting body morphological changes.
