沼气肥渣是在厌气条件下通过各类微生物的协同作用,产生沼气后的一种优质肥料。它所含的难分解有机物,如木质素、蛋白质、多糖类,是蘑菇所需碳素和氮素的主要来源;它的灰分物质有蘑菇所需的微量元素:钙、钾、镁、铁。沼气发酵的液化、产酸、产甲烷三个阶段,基本上完成了蘑菇堆料过程中的理化变化。特别是在厌气条件下,杂菌和虫害都无法生存。我们将运转正常的一个7m~3沼气池的材料,根据产气后碳含量损失35.4％,氮含量 Biogas fertilizer is a kind of high-quality fertilizer after producing biogas through the synergistic effect of various microorganisms under anaerobic conditions. It contains difficult to decompose organic matter, such as lignin, protein, polysaccharides, mushrooms are the main source of carbon and nitrogen; its ash content of mushrooms have the necessary trace elements: calcium, potassium, magnesium, iron . Biogas fermentation liquefaction, acid production, methanogenic three stages, basically completed the process of mushroom stacking material changes in the physical and chemical. Especially in anaerobic conditions, bacteria and pests can not survive. We will operate a normal 7m ~ 3 digester material, according to the loss of carbon content after gas production 35.4%, nitrogen content
