Abstract:

With the development of spectral technology,the spectral analysis methods on plant have become an important means of monitoring the information of crop growth and nutrition.The research advances that monitor five indexes such as leaf area index(LAI),biomass,water content,chlorophyll content,and nitrogen content of crop growth and nutrition by the spectral technology were reviewed.The prospects of applying the spectral technology in monitoring the information of crop growth and nutrition were put forward.

Key words: spectral technology, spectral reflectance, monitoring, crop growth, plant nutrition;

摘要：

随着光谱技术的发展,植物光谱分析方法已成为监测作物生长与营养信息的重要手段。通过概述利用光谱技术监测作物叶面积指数(LAI)、生物量、含水量、叶绿素及氮素五项指标的研究进展,对光谱技术在作物生长与营养信息监测方面的研究进行了展望。
