氮素胁迫下水稻高光谱特征研究
Research on Hyperspectral Characteristics of Rice under Nitrogen Stress
摘要
Abstract
Nitrogen is an essential element of a lot of rice growth, timely and accurate monitoring of nitrogen nutrition of rice, rice rational fertilization on yield, optimizing quality and reduce water pollution is important.Rice nutritional status of remote sensing diagnostic technique has a simple, non-destructive, rapidly and other characteristics have been widely studied and applied national experts.In this experiment, the sun on the 4th Founder varieties of rice, for example, through field experiments,, using hyperspectral remote sensing technology, collecting six nitrogen levels in rice canopy rice canopy image,measured the spectral reflectance of rice canopy,the results show:rice canopy reflectance with different nitrogen content had a significant correlation can be qualitatively from the graph roughly distinguish severe nitrogen defi-ciency, normal nitrogen fertilizer, excessive nitrogen fertilization.Next step is to find a combination of the spectral curve of nitrogen nutrition diagnosis Rice sensitive bands, provide the basis for future rice canopy nitrogen diagnostic model.关键词
