摘　　要：以沼气池、太阳能牛圈(暖圈)、卫生户厕(看护房及厕所)、集水系统(蓄水窖)、滴灌系统(节水设施)为特征的西北果园"五配套"生态养牛模式(西北模式);以沼气池、牛舍、厕所、日光温室为特征的北方"四位一体"生态养畜模式(北方模式);以牛舍、沼气池、果园为特征的南方"三结合"生态养畜模式(南方模式);先利用畜粪生产沼气,再对沼气生产的产物沼气、沼液、沼渣(简称"三沼")进行综合利用的牛粪综合利用模式的构建。本文对以沼气为纽带的生态养牛的各种模式的技术路线、基本要素、系统运行、配套技术、效益进行了分析。Three types of ecological cattle production models were introduced here. Northwest orchard type is composed of biogas reactor pool, solar heating cattle feedlot,sanitation toilet,water collection pool and water-saving irrigation system. North type is composed of biogas reactor pool, toilet, cattle feedlots and greenhouse, and South type is a combination of cattle feedlot, biogas pool and orchard. In those systems, cattle manure was used for biogas production and the biogas, liquid residue and solid residue of biogas production were all comprehensively utilized. Technological routes, basic components, system running, supporting techniques and economic benefit of these systems were thoroughly analyzed.
