The Selection of Proper Formule of Pleurotus eryngii、Stropharia rugosoannulata Farlows、Grifola Frondosa Mother Culture Medium

The selection of Pleurotus eryngii、Stropharia rugosoannulata Farlow、Grifola Frondosa Mother Culture Medium and proper Mother Culture Medium nutritional grads more analyzed in the paper.The research shows that:of the five kinds of Mother Culture Medium(PDA Medium,PDA enriched Medium,wheat bran Medium,peptone dextrose agar Medium,apple juice Medium.)and the six nutritional grads(1～6),the mycelium of Pleurotus eryngii grows best on apple juice culture Medium at nutritional grads A3;the mycelium of Stropharia rugosoannulata Farlows grows best on wheat bran Medium at B5;the mycelium of Grifola Frondosa on PDA enriched culture Medium at D4.
