摘要
对泸州老窖4种不同窖龄的窖泥进行研究,结果表明,窖泥中微生物数量规律、窖泥土壤水解N、速效K、有机质含量均为400余年窖龄>100余年窖龄>40余年窖龄>20余年窖龄。窖泥中土壤微生物与土壤酶活性间均呈正相关。通过各因子对窖泥中土壤微生物总数、土壤酶活性的通径分析发现:速效P、水解N、蔗糖酶和过氧化氢酶是影响微生物总数量的主要因子。
The research on four kinds of pit mud of different pit age of Luzhou Laojiao suggested that microbe number, sucrase activity, alkaline hydrolytic N content, rapidly-available K content, and organic substances content in pit mud were the highest in 400-year pit, then in 100-year pit, then in 40-year pit, and the least in 20-year pit. There was positive correlations between soil microorganism and soil enzyme activity. Through pathway analysis of each factor on soil microbe number and soil enzyme activity, it was found that rapidly-available P, alkaline hydrolytic N, sucrase, and catalase were the main factors influencing the total number of microorganism.
