苏北地区“猪-沼-菜”循环农业模式研究

Study on the‘Pig-Biogas-Vegetable'Circulation Agriculture Model in Northern Jiangsu Area

宿迁是农业大市,种植业和养殖业是农村经济的两大支柱产业,农业废弃物资源化利用任务十分艰巨。现以规模养殖场畜禽粪便无害化处理、资源化利用为切入点,实现"三废"源头治理;产出物为日光能温室生产提供能源和肥料,实现与日光能温室高效生产相耦合;残留物用于生产基质或商品有机肥,实现"三废"零排放;通过废弃物的循环利用,构筑种养有机结合、机理相互促进、生产高效低耗、效益同步提高的新型复合模式。该文以宿迁市泓润农牧科技有限公司为案例,探索了苏北地区农业废弃物循环利用模式。

Suqian is a big agricultural city,of which the planting and feeding are two important pillar industries of its rural economy. But it is a very difficult task of the comprehensive utilization of agricultural wastes. This study is based on the harmless treatment and resource utilization of livestock manure in scale raising farms, achieving source control of ‘Three Wastes’ ~the output of which was to provide the energy and fertilizer for the greenhouse,achieving the phase coupling with the high-efficient production of greenhouse~ the residue of which was used to produce medium and commercial organic fertilizer,achieving zero discharge of ＇Three Wastes＇. The recycling of wastes constructed the new compound model which the organic combination of planting and feeding, promoted mechanism each other. The high efficiency and low consumption of production benefited improvement at the same time. Taking Suqianhongrun Agriculture and Animal Husbandry Technology Co. , LTD as example, the model of recycling agricultural waste in northern Jiangsu area was explored.
