Abstract

Studies on the spectral reflectance of canopy and leaves of various cottons were performed. Spectral reflectance of six variety cotton over the 350-2500 nm range with a spectral resolution of 3 nm were obtained this study. In the early growth the spectral reflectance of cotton canopy increased with time, but in the later growth the spectral reflectance of cotton canopy decreased with time. In the main stem of cotton, the spectral reflectance of leaf decreased with leaf position up. The spectral reflectance of leaf increased with addition of leaves. The curve of spectral reflectance was up with water losing of leaf. In the single leaf, the spectral reflectance in leafstalk was higher than the spectral reflectance in edge of leaf. The action of derivative spectra on eliminating background influence on cotton canopy spectra and that of vegetation indices on determining agricultural parameters were analyzed. The results show that the position and slope of red edge of canopy spectral reflectance of cotton are certainly correlative to fractional vegetation cover.
