中部地区生态果园的沼气系统

EXPERIMENTAL STUDY OF THE ECOTYPIC ORCHARD WITH BIOGAS AS A LINK IN MID REGION OF CHINA

针对中部地区生态果园内的沼气系统 ,即沼气、太阳能日光温室、微型沼气地炕及猪舍等关键技术进行了试验研究 ,并从技术经济方面分析评价了以沼气为纽带的中部地区生态果园模式的可行性 ,结果表明本文研究开发的沼气、太阳能日光温室、微型地炕及猪舍等关键技术能将微生物 (沼气 )、动物 (猪 )、植物 (苹果树 )紧密地结合起来 ,果品生产过程中淘汰了化肥和农药 ,可以生产出质量较高的生态型无公害果品 ,形成生态农业良性循环体系 ,经济效益、环境效益和社会效益明显 ,对合理调整农业产业结构和发展农村经济有重要的参考价值。

A new mode of ecotypic orchard with biogas as a link in mid region of China was presented, which is based on ecology、economics and energy science. The results show that the biogas technology, piggery heating system with subminiature kang, the utilization technology of substituting the ferment residues (i.e. bio dross and bio liquid) for pesticide and chemical fertilizer, etc. are feasible in the extreme. Simultaneously , the biogas technology can be used to organize the individual agricultural technology (i.e. raise pig, pomiculture, forage grass, etc.) properly to produce pollution free fruits and vegetables. In the model the biogas plays a role as a linkage between plantation and breeding, link the plantation and breeding together and improve each other, and forms a benign ecology cycle which can provide social and economic benefit.
