摘　　要：为了解近红外光谱(NIRS)法与经典方法(凯氏定氮法、烘干法)检测饲用玉米质量的准确性与效率,试验采集80个饲用玉米样品,分别用NIRS法和经典方法测定了粗蛋白和水分含量,分析了两种方法测定的差异。结果表明:NIRS法和经典方法测定样品粗蛋白和水分含量的结果均能达到相应国家标准的要求,两种方法所得测定值的差异不显著(P>0.05),但经典方法繁琐费时、检测成本高、危害人体健康和生活环境,而NIRS法简便高效、安全环保,适合在饲料企业规模化应用。说明NIRS法更适用饲用玉米质量的检测。In order to understand the accuracy and efficiency of near infrared spectroscopy(NIRS) and classical methods(Kjeldahl method of nitrogen determination and drying method) in the quality determination of forage maize, 80 forage maize samples in the experiment were collected for the determination of crude protein and water content by the NIRS and the classical methods, respectively. At the same time, the differences between the two methods were analyzed. The results showed that the results of crude protein and water content of samples determined by NIRS method and classical method could meet the requirements of national standards. There was no significant difference between the two methods(P>0.05),but classical method was time-consuming, costly and harmful to human health and living environment, while the NIRS method was simple, efficient, safe and environmentally friendly, which was suitable for large-scale application in feed enterprises. The results indicated that NIRS method was more suitable for the quality detection of feed corn.
