摘　　要：利用红外光谱及电镜扫描技术对窖泥中的结晶检测分析,结果表明其主要成分为乳酸亚铁、乳酸镁和乳酸铜。结合不同退化程度的窖泥的理化指标,探究人工老窖窖泥退化原因,优化窖泥养护方案,为人工老窖的培养与养护提供理论基础。The crystal of pit mud was detected by infrared spectroscopy and scanning electron microscopy. Result showed that the main components of the crystalline were ferrous lactate, magnesium lactate and copper lactate. Combining with the physicochemical indicator of pit mud with varying de- grees of degradation, the degradation reasons of mud pit were explored and the maintenance plan were optimized, in order to provide a theoretical ba- sis for cultivation and maintenance of the artificial old cellar.
