黑木耳(Auricularia auricula),俗称木耳、光木耳,属担子菌纲,银耳目,木耳科,木耳属。黑木耳营养丰富,是人们喜爱的珍贵食品。据分析,每500克干耳中含有53克蛋白质、1克脂肪、325克醣,还有磷、钙、铁和多种维生素,并含有人体所需的8种氨基酸。维生素B_2的含量是米、面、蔬菜的10倍。铁质含量比肉高100倍。钙的含量是肉的30～70倍,可谓是“荤中之素、素中之荤”。黑木耳还对多种疾病有一定的疗效。历年来黑木耳生产栽培都采用树棒,产量很不稳定,每百斤木棒高的可收3～4斤,低的仅几两,且黑木耳的生产与林业发展产生一定的矛盾。我所从1959年开始就开展利用锯木屑代替木棒 Auricularia auricula (Auricularia auricula), commonly known as fungus, fungus, is Basidiomycetes, white fungus, fungus, fungus. Black fungus nutrient-rich, is people’s favorite precious food. According to the analysis, each 500 grams of dry ears contains 53 grams of protein, 1 gram of fat, 325 grams of sugar, and phosphorus, calcium, iron and vitamins, and contains the body’s eight kinds of amino acids. Vitamin B_2 content is rice, noodles, vegetables 10 times. Iron content 100 times higher than meat. Calcium content is 30 to 70 times the meat, can be described as “meat in the element, the element of meat”. Black fungus also has some effect on a variety of diseases. Over the years black fungus production and cultivation are using tree sticks, the output is very unstable, high per kilogram of wood can be received 3 to 4 pounds, low only a few two, and black fungus production and forestry development have some contradictions. From 1959, I started to use sawdust instead of sticks
