Effect of Different Sealing Methods on Mycelium Growth of Mushroom

In this paper,the effects of 7 sealing methods on mycelium growth of Pleurotus eryngii and Flammulina velutipes were investigated.The results showed that the plastic ring + plastic cover was the best and the mycelium grew healthy,the mycelium growth speed of Pleurotus eryngii and Flammulina velutipes reached 8.0mm and 4.3mm per day,respectively,the contamination rates were respectively 4.0% and 4.7%;the time of which material bag was full of mycelium was advanced by 11 days and 12 days,respectively,compared with the controll.With the sealing method of rope + sponge,the pollution rates of Pleurotus eryngii and Flammulina velutipes were respectively 3.3% and 4.0%,the mycelium growth speed reached 7.7mm and 4.4mm per day,respectively,the time of which material bag was full of mycelium was advanced by 10 days and 13 days,respectively,compared with the controll.The sealing method of micro porous material could improved the growth speed of mycelium,the mycelium growth speed reached 8.3mm and 5.0mm per day,respectively,but the pollution rate was the highest up to 10.7% and 9.3%,respectively and the weight loss of material bag was the highest.With methods of plastics ring+cotton and plastics ring+paper,the time of which material bag was full of mycelium was advanced by 7-12d compared with the control,but the pollution rate was the higher.
