规模猪场养分管理工程技术模式分析研究

随着我国规模化畜禽养殖业的不断发展,环境保护和养分管理两大问题日益突出。该文以规模猪场为研究对象,介绍了国外养分管理模式,总结分析了我国以沼气技术为主的规模猪场养分管理工程技术模式的应用现状、技术特点和存在问题,并提出了适合我国规模养猪发展的养分管理框架。结果表明,我国现有的养分管理模式偏重于前端的粪污处理,而后续的养分循环脱节严重,导致综合效益无法充分体现。通过构建新的养分管理框架和模式,提升政府支持和主导地位,提高养殖业主和农户的积极性,寻求养殖规模、粪污水量、种植规模、种植模式等的合理匹配才能实现养分在种植和养殖业的双向高效循环。

Nutrient Management Engineering Mode of Intensive Pig Farms

With the development of large-scale livestock farming in China,two major problems(environmental protection and nutrient management)are increasingly prominent.In the present study,application status of nutrient management based on biogas technology was analyzed,the technical characteristics and existing problems of biogas application modes were investigated and the suitable nutrient management framework was put forwarded.The results indicated that the existing nutrient management mode in China was inclined to the front-end manure treatment,while the subsequent nutrient cycle was seriously disjointed,and the comprehensive benefits could not be fully reflected.Building a new nutrient management framework and mode,enhancing the government's support and leading position,enhancing the enthusiasm of breeding owners and farmers,and seeking a reasonable match of breeding scale,manure and sewage quantity,planting scale and mode,etc.,could realize the efficient bi-circulation of nutrients in planting and breeding industry.
