摘　　要：针对当前我国干旱山区生态循环设施农业存在生产单元组合集中连体利用率不够、沼肥和秸秆循环使用效率低、农药化肥使用超标等问题,文章利用两日光温室间空闲地建造蘑菇房,既可用于食用菌生产,也可作为库房用于果蔬贮藏;通过棚顶集雨及沼气沼液沼渣多层次再利用、果蔬种植中CO2气体补施、食用菌菌渣再循环等形成"八位一体"的多模块循环生态农业系统;经过试验优化食用菌配方、沼液沼渣利用、CO2施肥等技术,达到"水沼肥气热渣"循环利用,实现山区农业资源科学合理配置和农产品绿色、安全、高产和优质生产。At the present time,the facility agriculture in Chinese arid mountainous areas has problems of insufficient centralization of production units,low recycling efficiency of biogas fertilizer and crop straw,excessive use of pesticides and chemical fertilizers. In this paper,a mushroom house was built between two solar greenhouse,cultivating mushroom and also as a storeroom for fruits and vegetables. A ecological＂8-units in one＂system are formed through the roof rainwater collection,multi-level reuse of biogas and biogas digestate,supplementary application of CO2 for fruit and vegetable cultivation,and recycling of mushroom residue. The formula of mushroom cultivation,utilization technology of biogas fertilizer,supplementary application of CO2 and some other technologies,were optimized through experiments,and obtained the cyclic utilization of ＂water-biogas digestate-gas（CO2）-mushroom residue＂,realizing rational scientific allocation of agricultural resources and producing high quality agriculture products in mountainous areas.
