菌糠是农作物秸杆与化肥等复配料供食用菌生长后的废弃物,菌糠中残留着大量的粗纤维、木质素、菌丝体,这些菌丝体含有大量的蛋白质、氨基酸、碳水化合物、多种维生素和微量元素。通过物理与生物技术,可以将这些物质加工成很好的饲料和优质的有机肥,形成从农作物、家畜禽→秸杆、粪便→食用菌→菌糠→饲料、有机肥→农作物,家畜禽的食物链,有效地保护了农村的生态环境。 The fungus bran is a kind of waste material after the complex ingredients such as crop straw, fertilizer and the like are used for growth of the edible fungus. A large amount of crude fiber, lignin and mycelium remain in the bran, and these mycelia contain a large amount of proteins, amino acids, carbohydrates , A variety of vitamins and trace elements. Through physical and biological technology, these materials can be processed into good feed and high-quality organic fertilizer, forming from crops, livestock and poultry → straw, faeces → edible fungus → bran, feed, organic fertilizer → crops, livestock The food chain of poultry effectively protected the rural ecological environment.
