“猪-沼-构树-猪”生态循环模式助推农村“以气代煤”进程

The Eco-cycle Model of the “Pig-Biogas-B. papyrifera-Pig” to Boost the Healthy Aquaculture Development

在国内食品安全和环境保护双重压力下,国内养猪业发展生态健康养殖模式是必然趋势。"猪-沼-构树-猪"生态养殖模式是以沼气处理工程为纽带,把猪场粪污变废为有机肥,用于种植构树;反过来构树叶生物发酵处理为饲料,用于养猪生产的一种新兴生态循环养殖模式。该模式推广应用可以消纳猪场粪污,提供可再生性清洁能源,推进农村"以气代煤"的进程,改善农田土壤,优化环境,降低养猪成本,是经济效益、社会效益和生态效益有机统一的生态循环健康养殖发展模式。

Under the double pressure of domestic food safety and environmental protection,the development of ecological health cultivation model of pig industry in China is an inevitable trend. ＂Ecological farming model pig-biogas-Broussonetia papyrifera-pig＂is the biogas treatment project as a link,the piggery waste turning waste into organic fertilizer for planting in Broussonetia papyrifera; Broussonetia papyrifera leaf fermentation processing for feed,for a new ecological cycle breeding pattern of pig production. Application of this model can be in piggery wastewater,providing renewable clean energy,promote the rural areas to ＂substitute gas for coal ＂ process,to improve the soil,optimize the environment,reduce production cost,ecological economic and social and ecological benefits of organic unity of the circulation of healthy aquaculture development mode.
