摘要： 为探索添加外源微生物对堆肥起始工艺参数的影响，进而提出二次调控工艺参数的意义。本研究分别添加0%、0.25%、0.5%、0.75%、1% 5 种不同质量浓度的嗜热菌，研究微生物加入后对含水量、酸碱度(pH)、电导率(EC)、全碳、全氮、碳氮比的不同影响。结果表明：1%加菌组水分含量较对照增加幅度为5.82%；pH、EC均有不同程度的改变；0.25%加菌组含碳量较对照降低幅度为9.20%；0.75%加菌组全氮含量较对照下降幅度为35.33%；0.75%加菌组碳氮比较对照增大幅度为4.34%。以上结果综合表明，加入不同浓度的外源菌，菌悬液会导致堆肥起始工艺参数不同。

Abstract: In order to explore the influence of added exogenous microbes on compost starting process parameters, and study the change of compost starting process parameters with microbial and put forward the significance of the secondary regulation technology parameters. The effect of microbe on water content, pH, EC, total carbon, total nitrogen and carbon nitrogen ratio was studied by adding five different concentrations (0%, 0.25%, 0.5%, 0.75% and 1%) of thermophiles respectively. The results showed that the water content of 1% microbe treatment was 5.82% higher than that of control; PH and EC changed in different degrees; the carbon content of 0.25% microbe treatment was 9.20% lower than that of control; the total nitrogen content of 0.75% microbe treatment was 35.33% lower than that of control; the carbon nitrogen ratio of 0.75% microbe treatment was 4.34% higher than that of control. The results suggested that bacteria suspension could lead to different compost starting process parameters by adding different concentrations of exogenous microbe.
