The Experiment of Cultivating Lentinus edodes Using Poplar Wood Processing Waste Materials Instead of Hardwood Sawdust

[Objective]The experiment of cultivating Lentinus edodes using poplar sawdust or poplar bark instead of hardwood sawdust was conducted in order to make full use of poplar wood processing waste materials.[Method]Effects of different formulas on bacteria survival rate,mycelial growth,production of fresh mushroom were studies.[Result]According to the test results of L.edodes cultivation,using 100% poplar sawdust or 100% poplar bark instead of hardwood sawdust as main medium,the mycelia growth was slower,the yield of fruit body was lower.While using 50% poplar bark and 50% hardwood sawdust mixture as main medium,the mycelia growth was best,the yield of fruit body was close to conventional hardwood sawdust formulation.[Conclusion] It was feasible to cultivate L.edodes using poplar bark partly instead of hardwood sawdust.
