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.
研究了不同水氮処理對水稻葉片水勢及冠層光譜的影響，確立了葉片水勢與冠層反射光譜的相關關系。
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.
本文通過對4個感染不同等級稻葉瘟的水稻冠層反射光譜進行測試，竝對光譜反射曲線進行微分分析，研究了綠光區、紅光區和近紅外區反射光譜的變異特征。
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.
通過分析水稻葉片氮含量與冠層光譜反射率及植被指數之間的相關性和定量關系，測試竝評價便攜式作物氮素監測儀的工作性能。
