木薯渣中纤维素、半纤维素、木质素含量分别为30.9％、6.9％、9.5％,含氮量为1.02％,还含有其他碳水化合物,适于平菇生长。作者做过三年栽培试验,投入产出比大于1:3,而且栽培周期仅70天。种菇后的废料因纤维索、木质素含量大幅度下 The contents of cellulose, hemicellulose and lignin in cassava residues were 30.9%, 6.9%, 9.5% and 1.02% respectively. Other carbohydrates were also found in the cassava residue, which was suitable for the growth of Pleurotus ostreatus. The author has done three years of cultivation experiments, input-output ratio greater than 1: 3, and the cultivation period of only 70 days. After the mushroom waste due to fiber cable, lignin content significantly
