分析了栽培基质中多种营养源的产量和质量效应,结果表明,香菇菌丝对栽培基质具有营养选择性,选择性表现在营养因子的物理化学存在形式、营养因子间的相互作用以及香菇的产量和质量水平对营养的需求。营养的选择性也是保持栽培基质中有效养分平衡的基础,根据营养选择性配置了在香菇栽培基质中用量为8％的添加物,并获得优于对照的产量和质量效应。 The results showed that mycelium of Lentinula edodes was nutritionally selective to the culture medium, and the selectivity was manifested in the form of physicochemical existence of nutrition factors, the interaction between nutrition factors and the growth of mushroom The level of nutrition and yield and quality requirements. Nutrient selectivity is also the basis for maintaining an effective nutrient balance in the culture medium. Nutrients are selectively added at concentrations of 8% in the mushroom substrate and yield and quality effects are better than those in the control.
