以往栽培玉蕈、滑菇和香菇等,大多采用以锯屑为主的培养基。例如:在培养玉蕈和滑菇时,米糠和锯屑的混合比为1:8至1:9。培养基主要是以锯屑中的纤维素和木质素作为营养源,以米糠中的微量元素作为补充养分。但是,采用锯屑作食用菌的培养基,也有其不利的一面,如某些树种的锯屑含树脂量较高,使用前必须将其堆制沤熟,这样不但麻烦,而且费时。此外,锯屑的来源还受到地区性的限制;更重要的是,仅用锯屑作培养基营养不足,必须依靠米糠等来补充其氮、磷、钾。日本的今村好信等人发现,在下水道污泥中,由于有手纸或厨房垃圾的缘故,含有大量的纤维素
In the past cultivated jade mushrooms, mushrooms and mushrooms, etc., mostly used sawdust-based medium. For example, when cultivating Tamarindus and Skoog, the mix ratio of rice bran and sawdust is 1: 8 to 1: 9. The medium mainly uses the cellulose and lignin in the sawdust as nutrient sources and the trace elements in the rice bran as the supplementary nutrients. However, the use of sawdust as a medium for edible fungi also has its downside. For example, some species of sawdust contain a high amount of resin and must be piled and cooked prior to use. This is not only cumbersome but also time-consuming. In addition, the source of sawdust is also subject to regional restrictions; more importantly, only the use of sawdust culture medium lack of nutrition, we must rely on rice bran to supplement its nitrogen, phosphorus and potassium. Japan’s Imamura good letter and others found that in sewer sludge, as a result of toilet paper or kitchen garbage, contains a lot of cellulose
