畜禽粪污资源化利用技术创新及其对农业生态系统的影响

Technological Innovation of Resource Utilization of Livestock and Poultry Manure and its Impact on Agro-ecosystem

畜禽粪污中含有大量重金属、病菌等有害物质,将其直接排放于生态环境中,不仅会对土壤及水资源造成污染,还会破坏生态平衡。现阶段,畜禽粪污资源化利用程度不高,传统处理方式达不到绿色、环保要求,且不利于农业可持续发展。畜禽养殖与农业相结合,是加强资源利用率的重要举措,通过科学的现代化处理技术,将畜禽粪污发酵、分解,可实现废弃资源再利用,其转化生成的有机肥料,能为农作物生长提供全面性营养物质,促进农业可持续发展。

Livestock manure contains a large number of heavy metals,bacteria and other harmful substances,which will be directly discharged into the ecological environment,not only will cause pollution to soil and water resources,but also destroy the ecological balance.At this stage,the resource utilization of livestock and poultry manure is not high,and the traditional treatment method cannot meet the requirements of green and environmental protection,and is not conducive to the sustainable development of agriculture.The combination of livestock and poultry breeding and agriculture is an important measure to strengthen the utilization of resources.Through scientific and modern treatment technology,livestock and poultry manure fermentation and decomposition can realize the reuse of waste resources,and the organic fertilizer generated by its transformation can provide comprehensive nutrients for crop growth and promote the sustainable development of agriculture.
