摘要
[目的]为了实现畜禽粪便的无害化处理和资源化利用。[方法]以新鲜牛粪、玉米秸秆和生物腐熟剂作为堆料,分别向鲜牛粪中添加0.05%、0.5%、1%的生物腐熟剂和5%的秸秆,以未添加任何物质的鲜牛粪为对照制定五种不同处理的好氧堆肥体系,研究了堆肥过程中全氮、全磷、全钾以及有机质的动态变化。[结果]堆肥结束时,全氮的相对含量增加,其中向牛粪中添加1%的生物腐熟剂可以减少牛粪中氮素的流失;不同处理对全磷、全钾含量影响不大,相对含量略显上升趋势。[结论]有机质含量呈阶段性变化,整体含量呈下降趋势。
【Objective】In order to achieve the innocuous treatment and resource utilization of livestock manure.【Method】 Fresh cow dung,maize straw and biological decomposition agents were as a pile material,then added 0.05%,0.5% and 1% of the biological decomposition agents and 5% of the maize straw.Five different treatments of aerobic composting systems were made and without any treatment of fresh cow dung as control,the dynamic changes of total nitrogen,phosphorus,potassium and organic during the composting were studied.【Result】The results showed that： at the end of the compost,the relative content of total nitrogen increased,while added 1% to cow dung decomposition of biological agents could reduce the loss of nitrogen.The influence of different treatments on total phosphorus,total potassium was not significant,the relative content of them increased slightly.【Conclusion】The organic content was periodically changed,and the total content decreased.
