1. a rice leaf total nitrogen content EO-1 hyperion estimation models construction method, it is characterised in that comprise the following steps:

  • Select multiple experimental plot, select multiple sampling points in each experimental plot;

    Oryza sativa L. key developmental stages is selected to carry out canopy spectra measurement;

    Each sampling point records multiple sampling spectrum, the spectra measurement as this sampling point of averaging;

    The Hyperspectral imaging of experimental plot is obtained by airborne imaging spectrum instrument;

    The multiple functional leafs gathering different parts at each sample point record rice leaf total nitrogen content;

    Spectral index or partial least-square regression method is used to build rice leaf total nitrogen content EO-1 hyperion estimation models.
