【摘要】 为了减轻堆肥过程中氨气释放的污染及氮素损失,以猪粪和稻草为原料进行了模拟堆肥试验,研究添加菌剂YX-3对猪粪堆肥处理过程中氮素转化的影响。结果显示:添加菌剂YX-3对堆体的温度无显著影响,均可达到堆肥高温无害化的要求,但可以降低堆体的pH值,加速堆肥腐熟。与对照相比,添加功能菌剂YX-3,可以显著降低堆体的铵态氮含量,减少氨气的挥发量;堆肥结束时,硝态氮、全氮含量较对照分别提高37%和11.7%。表明菌剂YX-3在猪粪堆肥过程中具有较好的降氨除臭和保氮的效果。更多还原

【Abstract】 In order to reduce the pollution of NH₃ emisson and nitrogen loss during pig manure composting,a simulated composting experiment was performed using pig manure and rice straw as raw materials,and the effect of adding microbial inoculum YX-3 on nitrogen transformation during the composting process was studied.The results showed that the microbial inoculum YX-3 had no significant effect on the temperature of the compost,meeting the requirement of high-temperature harmlessness of the compost;at the same time,YX-3 reduced the pH value of the compost and accelerated the compost decomposition.Compared with the control,the addition of functional microbial inoculum YX-3 significantly reduced ammonium nitrogen content of the compost and reduced the volatilization of ammonia;at the end of composting,nitrate nitrogen and total nitrogen contents of the compost increased by 37% and 11.7% respectively.It demonstrated that microbial inoculum YX-3 had good effects on reducing ammonia emission,deodorizing and nitrogen conservation in the process of pig manure composting.更多还原
