摘要
以紫茎泽兰为试材,采用重铬酸钾法、DNS法和重铬酸钾硫代硫酸钠法测定复合菌剂强化紫茎泽兰堆肥后的纤维素、半纤维素和木质素含量,研究了复合菌剂对紫茎泽兰堆肥的影响。结果表明:堆肥前期纤维素、半纤维素和木质素含量显著下降。在第3天时,纤维素、半纤维素、木质素分解率比对照组分别提高了17.0%、27.7%、11.3%。结果表明复合菌剂能促进紫茎泽兰的降解。
Taking Eupatorium adenophorum Spreng as test materials,the straw compost was enhanced by the composite microbial agents.The contents of cellulose,hemicellulose and lignin were determinated by the potassium dichromate method,the DNS method and the potassium dichromate-sodium thiosulphate.The results showed that the contents of cellulose,hemicellulose and lignin decreased significantly in the early period of compost.On the 3rd day of compost,the decomposition rate of cellulose,hemi-cellulose and lignin increased by17.0%,27.7%and 11.3% over the control check group respectively.The results indicated that the composite microbial agent could promote the degradation of Eupatorium adenophorum Spreng.
