培养料是蘑菇生产的物质基础,微生物群体发酵的综合产物。因此,探索有益微生物最适宜的发酵环境条件,抑制或消灭不利的微生物,并控制物质的转化,制成优质的培养料,对提高蘑菇产量具有重要的意义。最近国外报导,培养料经后发酵可以提高蘑菇产量,南朝鲜每平方米产量,从1～2公斤提高到12.7公斤;美国每平方英尺从3磅提高到13～22磅。我们实验也取得同样的结果。但对其内在变化至今未见阐述。本实验于1979年夏季开始,着重研究后发酵中的微生物区系动态、碳氮转化与蘑菇产量的关系。
Cultivation material is the material basis of mushroom production, the microbial fermentation of a comprehensive product. Therefore, it is of great significance to explore the most suitable fermentation conditions for beneficial microorganisms, inhibit or eliminate unfavorable microorganisms, and control the conversion of materials to produce high-quality culture materials. According to the latest reports from foreign countries, the cultivation of feedstock after fermentation can increase mushroom production. The output per square meter in south Korea has risen from 1 to 2 kg to 12.7 kg; the United States has increased from 3 to 13 to 22 pounds per square foot. Our experiment also achieved the same result. However, its internal changes have not been described so far. The experiment began in the summer of 1979 and focused on the dynamics of microflora in post-fermentation, and the relationship between carbon-nitrogen conversion and mushroom yield.
