摘要:本文重点研究了近红外漫反射分析技术在棉籽,尤其是毛棉籽的水分和油含量检测中的应用,包括近红外漫反射技术基本原理,开放式检测方式的优点分析。具体建立了毛棉籽水分和油含量的近红外分析模型,并随机抽样验证了检测模型的检验精度。从结果来看,定标的相关系数较高,,,,检测精度较高,检测结果完全可以达到代替传统检测方法的要求。同时,也利用部分样品建立了仁含油和仁出率的近红外检验模型,证明近红外方法也可以进一步应用于仁含油和仁出率的结果检测。

Abstract
In the paper, it is studied to analyze the moisture and oil content in gross cottonseed by near infrared reflectance spectroscopy (NIRS) technique. There is also including the basic theory of NIRS and advantage of open detecting mode. The calibrations of the moisture and oil content in gross cottonseed are built. The precision and accuracy of the moisture and oil content is clarified by random sampling. The correlation coefficient is high: of moisture and of oil. The calibration error (SECV) for the moisture and oil content in gross cottonseed are and separately. The result of NIRS prediction is proved that the NIRS method can replace the normal analysis pletely. Further studies on the calibration of oil content in nucleus and rate of nucleus in gross cottonseed are built with part of samples. It is proved that NIRS method can be applied to detect the oil content in nucleus and rate of nucleus in gross cottonseed.
Keywords: NIRS, open
