大型生猪养殖企业生态循环农业发展现状及模式设计探讨——以建平正邦养殖有限公司为例

Discussion on Development Status and Model Design of Eco-circular Agriculture in Large-scale Pig Breeding Enterprises-Taking Jianping Zhengbang Aquaculture Co.,LTD as An Example

随着我国人口增加,工业化、城市化和农业现代化的推进,耕地、淡水、土地等资源的人均占有量减少,我国农业发展受资源短缺和环境恶化的约束越加突出。生态循环农业体系缺少产业之间和上下游产品之间循环、反馈、共生耦合的生产流程,严重制约了农业的可持续发展。阐述了区域农业发展的现状,探索了我国大型生猪养殖企业内部发展生态循环农业模式“生猪养殖—废弃物综合利用(有机肥)—玉米种植—秸秆综合利用(有机肥)—饲料加工—生猪养殖”,打破了传统的种植养殖模式,改善种、养、加工三结合下的生猪生态养殖方法,为不同区域、不同规模的养殖企业发展内部循环农业提供参考。

With the increase of population,and promotion of industrialization,urbanization and agriculture modernization,the per capita possession of arable land,fresh water,land resources has decreased.The constraints of resource shortage and environmental degradation on agricultural development have become increasingly prominent.The ecological-circular agriculture system mainly involving the production process of circulation,feedback,and symbiotic coupling between industries,and upstream and downstream products,has not yet been established,which seriously constrained the sustainable development of agriculture.Explored the development of ecological-circular agriculture models as“pig breeding—comprehensive utilization of waste(organic fertilizer)—corn planting—comprehensive utilization of straw(organic fertilizer)—feed processing—pig breeding”within large pig breeding enterprises through investigating the current situation of regional agricultural development.It broke the traditional planting and breeding model and improves the ecological breeding methods of pigs by the combination of planting and breeding,which provided reference for the development of internal circular agriculture in different regions and different scales of aquaculture enterprises.
