近红外光谱(NIRS)为一种无损、快捷,并可实现同时进行多组分析的检测新型技术。首先对NIRS的检测原理进行技术层面的分析,并对近年来NIRS在土壤肥料检测分析中的应用进行进一步探讨。近红外反射光谱分析法近年来被广泛应用于各种样品中有机成分和其他性质的分析中,在土壤肥料及植物营养科学具有广阔的应用前景,因此为进一步分析其应用价值,文章除上述研究外,还对近红外反射光谱分析在土壤肥料及植物营养学科中的应用,以及存在问题展开了较为深入的探讨,以此分析其发展方向。
Near Infrared Spectroscopy (NIRS) is a non-destructive, fast, and novel technique for simultaneous multi-group analysis. First of all, the principle of NIRS detection technology for technical analysis, and in recent years, NIRS in soil and fertilizer testing and analysis of the application to further explore. Near infrared reflectance spectroscopy has been widely used in the analysis of organic components and other properties in various samples in recent years. It has broad application prospect in soil fertility and plant nutrition science. Therefore, in order to further analyze its application value, In addition, the application of near-infrared reflectance spectroscopy in soil fertilizers and plant nutrition and its existing problems are discussed in more depth, and its development direction is analyzed.
