食用菌同其他生物一样都需要摄取一定的营养物质。不同种食用菌摄取营养的方式不同,一般可分为三种类型,即腐生类型、共生类型、兼性寄生类型。不论食用菌属于何种营养类型,归根结蒂,它们都是从基质中摄取碳原、氮原、无机盐和维生素等营养物质。 (一)碳源:碳源是食用菌最重要的营养来源,它不仅能提供碳素以作为合成碳水化合物和氨基酸的原料,同时它又是重要的能量来源。食用菌所需要
Edible fungi, like other organisms, require certain nutrients. Different kinds of edible fungi intake of nutrients in different ways, generally can be divided into three types, namely saprophytic type, symbiotic type, facultative parasitic type. Regardless of the type of edible mushrooms, in the final analysis, they are all taken from the substrate carbon nutrients, nitrogen, inorganic salts and vitamins and other nutrients. (I) Carbon Source: The carbon source is the most important source of nutrients for edible fungi. It not only provides carbon as a raw material for the synthesis of carbohydrates and amino acids, but it is also an important source of energy. Edible fungus needs
