The leaves residual and bark of Eucommia ulmoides Oliver was used to culture Hericium,Flammulina velutipes and Pleurotus ostreatus,some rules of the degradation of hemicellulose,cellulose and lignin had been got. The mass fraction of hemicellulose,cellulose and lignin was 9. 834 mg /g,38. 997 mg /g and 164. 667 mg /g in the leaves residual,32. 297 mg /g,108. 313 mg /g and 44. 667 mg /g in the bark of Eucommia ulmoides Oliver. When Hericium was cultured 68 days,the mass fraction of hemicellulose,cellulose and lignin was dropped 61. 0%,80. 3% and 12. 5%.When Flammulina velutipes was cultured 61 days,the mass fraction was dropped 37. 3%,82. 5% and 23. 1%. When Pleurotus ostreatus was cultured 58 days,the mass fraction was dropped 30. 3%,40. 7% and 57. 1%. The results of solid state fermentation of the Eucommia ulmoides bark showed that the full culturing time of liquid spawn was 4 days in advance than that of solid spawn when Hericium was cultured,while there was only 2 days when the Flammulina velutipes and Pleurotus ostreatus were cultured. On the degradation of lignin,the solid spawn of Hericium and Pleurotus ostreatus were better,while the two types of spawns of Flammulina velutipes had little difference and the effects were poor.On the degradation of cellulose,the liquid spawn of Hericium and Flammulina velutipes were better,but the two types of spawns of Pleurotus ostreatus had little difference and the effects were poor. When the degradation of hemicelluloses was mentioned,two types of spawns of the three edible fungi had almost the same capabilities.
