Abstract:

The technology of near infrared reflectance spectroscopy (NIRS) has been widely used in many research areas, due to its fast speed, high efficiency, low cost and without any damage to environment, especially its timely usage in outdoor moniioring. This paper illustrates the principle and characteristics of NIRS, and introduces its applications in monitoring forage nutritional elements, seeds quality, plant composition, soil physical and chemical properties, grass insect pests diseases, and turfgrass management in color and planting. It also prospects the real-time dynamic monitoring for forage soil environment, root system distribution, carbon storage, range rodents damage and developing portable equipment for real time outdoor monitoring, so as to promote the application of near infrared reflectance spectroscopy (NIRS) technology in pratacultural science and technology and its application in production.

Key words: near-infrared reflectance spectroscopy(NIRS), forages production, grassland ecology, turfgrass management

摘要：

近红外光谱技术(NIRS)是一项快速、高效、无损的现代检测技术,已经在许多领域广泛应用,特别在野外检测更具有实时性。阐述了 NIRS技术的原理和特点,介绍了NIRS在牧草营养成分、牧草种子品质、草地植物组成、草地土壤理化性质、草地病虫害检测、草坪色泽及建植管理方面的应用。并对草地土壤环境、根系分配、碳源/碳汇、鼠害动态监测,以及开发适宜于野外观测的便携式实时监测仪器提出了展望,以推动近红外光谱技术在我国草业科技和生产中的应用。
