环境友好型规模化养猪场的建设研究

以深圳坪山农业园种猪场为研究对象,通过现场调查,查阅资料,监测农业园的水、土壤、大气环境质量,综合分析十多年来该养猪场对周边环境的动态影响,结果表明,至2004年该农业园用水质量属于清洁水平,土壤综合污染指数属安全级,从空气中氨气浓度和细菌数指标来看,场区空气质量比场外差,距离场区越远,空气质量越好,按相关标准评判,均处在卫生标准的允许范围。过去12年间,该农业园的土壤肥力逐年上升,土壤和农业园用水所含的5种金属元素有较小幅度升降。研究表明,规模化猪场通过合理选点、环保、种养结合、绿化、加强舍内废弃物管理等措施可以确保长期环境友好。

Study on the Approaches to Environment-friendlg Intensive Pig Farm

Pingshan Agriculture Garden(PAG) in Shenzhen was employed for this research to find the approaches leading to environment afriendly intensive pig farm.Combined with the early data completed within last 12 years,PAG profile,manure management,water,soil and air were investigated through 2004.The results showed that so far water,soil and air in PAG were safe compared with the related standards.The fertility of the soil in PAG was improved step by step during last 12 years.The contents of five kinds heavy metal were a little increased or decreased.The achievements were resulted from the measures taken by PAG as best site selection,sewage treatment system,recycling manure to forest and fruit land,building of plant hedge and clean manure in animal house.It concluded that the above integrated measure could lead to a environment friendly pig industry.
