摘  要：
以烟草废弃物为主要原料,在添加混合菌剂的基础上,研究不同鸡粪添加比例对烟草废弃物高温堆肥进程中温度、pH值、电导率、C/N比与种子发芽指数(GI)的影响.结果表明:添加鸡粪缩短了烟草废弃物堆肥达到高温(>50℃)的时间,延长了高温分解持续时间,加快了烟草废弃物堆肥腐熟进程,降低了烟草堆肥产品的生物毒性.添加不同比例的鸡粪烟草废弃物堆肥处理(烟草废弃物与鸡粪比例为1∶0.263或1∶1.373)都在堆肥3 d后进入高温分解阶段,较纯烟草废弃物堆肥处理进入高温分解阶段时间提前5d,高温持续时间分别延长5、7 d.3个处理中以烟草废弃物与鸡粪比例为1∶1.373处理效果较优,堆肥35 d时,堆肥完全腐熟(T值<0.6),堆肥产品基本没有生物毒性(GI=79.09%).

摘  要：
Tobacco waste was used as major materials to study effects of adding different proportions of chicken manure on temperature,pH value,electrical conductivity(EC),C/N ratio and seed germination index(GI) during high-temperature composting process based on adding mixed bacterial agent.The results showed that adding chicken manure shortened the time of reaching high temperature(>50℃),extended the time for pyrolysis,accelerated the composting process,and decreased the biotoxicity of compost.In composting treatments with different proportions of chicken manure(1:0.263 or 1: 1.373,the ratio of tobacco waste to chicken manure),the time of reaching high temperature were three days,which advanced five days in comparison with treatment without chicken manure,and the duration of high temperature prolonged five days and seven days,respectively.Among the three treatments,the treatment in which ratio of tobacco waste to chicken manure was 1:1.373 had better effect;compost was completely decomposed(T <0.6) at the 35th day,and the compost products barely had biotoxicity(GI=79.09%).
