近红外光谱分析技术及其在牧草种子质量监督检验上的应用前景

The Application of Near-Infrared Reflectance Spectroscopy in Seeds Quality Certification

近红外光谱(NIRS)的分析技术是一项高效、快捷检测样品中某种物质成分的分析新方法,近年来在农业、食品、医药、化工、纺织、环保等领域得到了广泛的应用。文章简要介绍了NIRS技术产生和探测的基本原理、方法和技术特点,回顾了其在植物种子研究方面的应用情况,然后从种子品种鉴定、种子纯净度鉴定、种子发芽率测定、种子水分含量和生活力测定等四个方面阐述了NIRS分析技术应用于牧草种子质量监督检验的意义和潜在价值。最后得出结论应用NIRS技术能降低种子检验成本、提高检验效率,还有助于扩大常规种子检验的范围和用途,因此NIRS应用于牧草种子质量检验有着重要的理论和实际意义。

Near infrared reflectance spectroscopy is a newly developed method capable of analyzing the content of specific compound in the detected sample quickly and efficiently.Near infrared reflectance spectroscopy has been wildly used in many fields such as agriculture science,food industry,medical industry,chemical engineering and protection of environment and so on.In the present paper firstly the principle,technique method and merits of near infrared reflectance spectroscopy were described.Then the application of near infrared reflectance spectroscopy to the seeds of many crops,i.e.wheat,rice,rape and apple,was reviewed and discussed in brief.Based on this introduction,the potential value of the application of near infrared reflectance spectroscopy to the grass seeds quality certification was discussed in the four areas,i.e.the grass seed variety discrimination,the standard percentage rate of grass seed germination testing,the scale of the content of grass seed moisture,and the evaluation of the grass seed vigor and the purity of grass seed.Finally,it was concluded that the application of near infrared reflectance spectroscopy to the grass seed quality certification is significant both in the academic and the technical areas because near infrared reflectance spectroscopy will not only improve the efficiency of grass seed certification,saving manual work and testing time,but also help expand the extent and application of routine quality certification of grass seeds.
