在毛木耳(Auricularia cornea)基础配方(CK)上,添加不同比例的豆粕(未发酵处理的二浸豆粕)为氮源,设计了5个毛木耳栽培基质配方,通过对菌丝长势、菌袋污染率、耳期染病率、生物转化率及耳片农艺形状等指标的分析,结果表明,在毛木耳栽培基质中添加一定量的豆粕,对菌丝生长具有一定促进作用,但实际添加量≥2%时,配方表现出污染率增高,耳片变小,耳片厚度降低,产量和生物转化率降低的现象,综合表明,在黄背毛木耳栽培基质中,不宜添加未经发酵处理的二浸豆粕直接用于生产。 In the basic formula (CK) of Auricularia cornea, different proportions of soybean meal (unfermented second-soaked soybean meal) were added as nitrogen source, and five hairy millet cultivars were designed. Through mycelial growth, The results showed that adding a certain amount of soybean meal in the culture media of A. millet increased the mycelial growth, but the actual addition rate was ≥ 2%, the formula showed that the pollution rate increased, the ear becomes smaller, the ear thickness decreased, the yield and the bioconversion rate decreased, the comprehensive shows that the cultivation of the material in the fungus, should not be added unfermented Immersed soybean meal directly for production.
