农业养殖废弃物是农村生态环境的重要污染源之一,养殖固体废物及废水资源化利用是控制农村环境污染的有效途径。文章提出了一种将种植-养殖-沼气-肥料有机结合的循环农业模式。该模式在湖北省大冶市金牛镇三阳农场应用,并对该农场生产运行情况进行跟踪调查和数据分析。结果表明:该模式不仅经济效益明显,而且彻底解决了养殖废弃物污染问题,真正实现了“零排放”。实践证明该模式适用于农村中小型种养基地,可为我国农村生态农业发展模式提供参考。
Agricultural waste culture is one of the most important pollution sources in rural ecological environment. It is an effective way to control rural environmental pollution by breeding solid waste and recycling wastewater. The paper presents a circular agriculture model that combines planting - culture - biogas - fertilizer. The model was applied in Sanyang Farm, Jinniu Town, Daye City, Hubei Province. The operation of the farm was tracked and analyzed. The results show that this model not only has obvious economic benefits, but also completely eliminates the pollution of farming waste and realizes “zero discharge”. Practice has proved that this model is suitable for small and medium-sized planting bases in rural areas and can provide reference for the development model of rural ecological agriculture in our country.
