canopy reflectance

基本解释

The investigation was conducted to study the relationship between canopy reflectance characteristics and leaf water potential in rice under different water and nitrogen levels.
研究了不同水氮处理对水稻叶片水势及冠层光谱的影响，确立了叶片水势与冠层反射光谱的相关关系。
Rice spectrum features at green, red and near infrared regions were studied by measuring and analysing rice canopy reflectance and differential spectrums with 4 levels of rice leaf blast.
本文通过对4个感染不同等级稻叶瘟的水稻冠层反射光谱进行测试，并对光谱反射曲线进行微分分析，研究了绿光区、红光区和近红外区反射光谱的变异特征。
The correlations and the quantitative relationships between LNC and rice canopy reflectance spectra were analyzed, and the performance of portable nitrogen monitoring instrument was evaluated.
通过分析水稻叶片氮含量与冠层光谱反射率及植被指数之间的相关性和定量关系，测试并评价便携式作物氮素监测仪的工作性能。
