野生田头菇菌株的驯化及其子实体营养成分分析

采自湖南洞庭湖大通湖区芦苇湿地的野生菌株,经鉴定为田头菇Agrocybe praecox。通过驯化实现人工栽培,栽培原料以芦苇屑为主,使用液体菌种和覆土栽培方式,初潮菇平均生物转化率为45.6%。营养成分分析表明：以芦苇屑为栽培培养基,子实体中矿物元素含量分别为K（2 190mg/kg）、Fe（16.2mg/kg）、Mg（59.7mg/kg）、Ca（33.4mg/kg）,必需氨基酸含量占比高达44.85%,谷氨酸、蛋氨酸、天冬氨酸含量高,是一种高蛋白、低脂肪、高钾低钠的食用菌。

Domestic cultivation and nutritional component analysis of wild strain of Agrocybe praecox

Artificial domestic cultivation of a wild strain of Agrocybe praecox collected from reedy wetland in the Datong Area of Dongting Lake, Hunan Province, is carried out. Reed shavings were mainly used as substrate. Using liquid spawn and soil-covering cultivation method, average bioconversion rates of the first-season mushrooms was 45.6%. Nutrient analysis showed that using reed shavings as substrate, the content of main mineral elements in fruiting bodies was K 2 190mg/kg, Fe 16.2mg/kg, Mg 59.7mg/kg and Ca 33.4mg/kg. The mushrooms were rich in glutamic acid, methionine and aspartic acid. The proportion of essential amino acid content was up to 44.85%. Agrocybe praecox is a kind of edible fungus with high protein, low fat, high potassium and low sodium.
