摘要
在传统农业循环经济"四位一体"模式中,结合现代分布式能源系统,提出禽畜养殖-沼气生产-能源供给-温室大棚-农业种植的"五位一体"农业循环经济新模式。根据我国粮食主产区的分布和地理环境,提出采用生物能源对系统内部进行结构优化设计。在该模式中,可有效提高农业资源的利用率,减少农业生产中化肥和农药的使用量,促进温室大棚和农业种植的增产增收,改变农业只能产出农产品的格局,形成工农商联合的新模式。促进可再生能源的开发和利用,增加农村清洁优质能源供应量并转化为收益。
With current social environment and energy issues becoming more and more prominent,in order to promote the rational use of resources,some rural areas have carried out exploration and research on agricultural circular economy model. In the"four-in-one"mode of traditional agricultural circular economy,combined with distributed energy system,absorption refrigeration and denitration process,a "five-in-one" agricultural circular economy model was proposed. In this model,utilization rate of biogas can be effectively improved,the use of chemical fertilizers and pesticides in greenhouse agricultural products can be reduced,and greenhouse agricultural products can be increased in production and income. The "five in one" has changed the pattern that agriculture can only export low-end agricultural products,forming a new model for the union of workers and peasants. It constitutes an integrated energy and ecological utilization system,promotes development of renewable energy,and increases supply of clean and high-quality energy in rural areas and converts them into income.
