促腐剂在鸡粪堆肥发酵中的应用研究

Effects of transformation promoter on fermentation of chicken manure compost

  • 摘要: 选用鸡粪和小麦秸秆为原料进行高温好氧堆肥,研究促腐剂在鸡粪堆肥发酵中的应用。结果表明,接种促腐剂可迅速提高堆肥初期的发酵温度,最高温度超过70℃,但发酵后期降温快,高温加快了堆肥的发酵。发酵20d种子发芽指数达到80%以上;发酵30d含氮量比对照高4.3%,含水量降低3个百分点。综合堆温、C/N、种子发芽指数各项腐熟度指标,接种促腐剂可使鸡粪堆肥腐熟时间比对照提前5d以上。接种促腐剂可降低物料对种子发芽指数的影响,显著缩短发酵时间,加快堆肥物料的水分挥发,使堆肥中的无机营养成分含量相对增加,从而提高鸡粪堆肥的质量。

     

    Abstract: Aerobium were added to the compost using chicken manure and wheat straw as raw materials. Effects of transformation promoter on the chicken manure compost fermentation were investigated. The results show that temperature of the compost is increased at the early composting stage by adding the transformation promoter, and temperature can reach to over 70°C, while the temperature is rapidly decreased at the late fermentation stage, and indicate the high temperature might speed up the fermentation process. Seed germination index(GI) of the treatment with inoculation of transformation promoter is about 80% after 20 days of composting. Compared to the control, there is a 4.3% increase of nitrogen content, and a 3.0% decrease of water content of the compost. With regarding to the maturity parameters such as temperature, C/N, GI, there is more than 5 day composting time reduction in the treatments with inoculation of transformation promoter. Our study suggests that the addition can reduce the adverse effects of material on GI, shorten composting time significantly, and further accelerate water volatilization of compost material. Meanwhile, contents of inorganic nutrients are relatively increased; therefore, the quality of chicken manure compost is improved.
