目前,生产蘑菇原种和栽培种的培养基,大多数用牛、马粪或鸡粪晒干粉碎后,再搭配一定比例稻麦秆堆制发酵而成。粪草培养基不仅稻麦秆用量大,而且花工多。采用人工合成培养基可以不用畜粪,并能增加稻麦秆发酵得率,节省原料和发酵场,花工少,成本低。同时,还可以改善环境卫生和劳动条件。我厂菌种场从1969年开始用人工合成培养基制种,十年来共生产60 At present, the production of mushroom species and cultivated medium, most of the cow, horse manure or chicken manure crushed, and then with a certain percentage of rice straw fermentation system. Dung grass medium not only large amount of rice straw, but also more flowers. Artificial synthetic medium can be used without manure, and can increase the yield of rice straw, saving raw materials and fermented field, less labor, low cost. At the same time, it can also improve sanitation and working conditions. My plant species field from 1969 with synthetic medium seed production, a total of 60 years of production
