蘑菇的原种和栽培种生产,一般都是采用发酵料制作,工序较繁,用工量大,成本较高。而且在菌种生产期间,若遇上梅雨季节,无法使培养料晒干,常常影响正常生产。为此,我们于1984年进行了生牛粪粉制种试验,取得了较好的效果,成品率达95～98％,菌丝生长茂盛。现简报如下。一、培养料制作主料是新鲜干牛粪粉70％,辅料为稻草及麦草(或粗糠及麦壳)22％、麸皮5％、石 The original mushrooms and cultivars of mushroom production, are generally produced using fermented materials, the process of more complex, large amount of labor, higher cost. And in the production of bacteria, if the rainy season, can not make the culture material to dry, often affect the normal production. To this end, we conducted a raw cow dung seed production test in 1984, and achieved good results, yield 95% to 98%, mycelium flourish. Now briefing as follows. First, the training material production Ingredients are fresh dry cow dung 70%, accessories for straw and straw (or bran and wheat husk) 22%, bran 5%, stone
