摘　　要：在对窖泥主要化学元素含量、窖池产酒效果测定的基础上,采用灰色关联度法对窖池产酒与窖泥成分的关联性进行量化分析。结果表明,窖泥中总C、总H、总N、氨N、总P、总S、Ca、Fe、Mg、K、Na的平均值分别是:6.09%、1.28%、1.22%、1.64‰、11.37‰、1.49‰、1.98%、3.25%、1.04%、2.73%、2.67%,各窖池间化学元素含量的变异系数较大。窖池的出酒率43.89%,优质品率平均值24.11%,窖泥对产酒效果,特别是优质品率贡献度高。窖泥化学元素变化与产酒关联度高,其中矿质元素对产酒效果的影响高于有机元素。与出酒率灰色关联度排序结果:Ca>Fe>总P>总S>氨N>Mg>总C>总H>K>Na>总N。与优质品率排序:Ca>Mg>Na>K>Fe>总P>总S>氨N>总C>总N>总H。窖泥成分与产酒效果的关联性分析为窖泥养护提供了参考。Applying grey relational analysis method,we had studied the relationship between content of main chemical elements in put mud and liquor yield.The results showed that the average value in pit mud of total C,total H,total N,ammonia N,total P,total S,Ca、Fe、Mg、K、Na,respectively is 6.09% and 1.28% and 1.22%,1.64 per thousand,11.37%,1.49% and 1.98% and3.25%,1.04% and 2.73%,2.67%.The coefficients of variation of these chemical components are large among the pits.The average rate of liquor yield is 43.89%in pit,the rate of high quality liquor is 24.11%,and the pit mud is help to improve liquor yield,especially to the high quality product.The chemical elements in pit mud are high relation to liquor yield,especially of mineral elements.The order of grey relational degree to rate of liquor yield：CaFetotal Ptotal Sammonia NMgtotal Ctotal HKNatotal N,and to rate of high quality liquor：CaMgNaKFetotal Ptotal Sammonia Ntotal Ctotal Ntotal H.This study provides a reference for the maintenance of pit mud and improve liquor yield.
