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.
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.
As a the core algorithms of a computer simulation model in the vegetation canopy reflectance model, Monte Carlo method can well explain and describe the interaction of leaves and photon.
