金针菇分解木材的能力较其它木腐菌弱,栽培后剩下的培养基残渣,一般为收获量的3～4倍(湿料重),至少还有一半未被利用。据日本的国松丰对新鲜的金针菇培养基残渣成分分析结果,水份45.3％、粗蛋白4.8％、粗脂肪1.9％、粗纤维28.19％。由此可见,金针菇的培养基残渣中尚有一定的营养成分。为此,笔者于1981年开始利用残渣进行栽培比较,至1983年共试验三批,现简报如下。
Flammulina can decompose wood more weakly than other wood rot fungi. The remaining medium residue after cultivation is usually 3 to 4 times of the harvest weight (wet weight), and at least half of it is unused. According to Japan’s Song Song Feng fresh flammulina vetch residue analysis of composition, water 45.3%, 4.8% crude protein, crude fat 1.9%, crude fiber 28.19%. Thus, Flammulina velutipes medium residue still have some nutrients. To this end, the author began to use the residue in 1981 compared to cultivation, to test a total of three batches in 1983, are briefings are as follows.
