Abstract: Through analysis of soil properties (for example, total salt content and pH value) and measurements of canopy field spectra of rice, 27 paired-samples were gotten. The relationships between canopy field spectra and the first derivative spectra of rice at milky-ripe stage and total salt content and pH value of soil were discussed initiatively. The results indicate that there are no significant correlations between total salt content and pH value of soil and canopy field spectra (the range of wavelength is between 350 and 1350 nm) of rice, and between total salt content and pH value of soil and vegetation indices, and between total salt content and pH value of soil and the locations and swings of red edges, but the correlation between total salt content and pH value of soil and the first derivative spectra of rice at milky-ripe stage is significant. Considering the first derivative spectra between 654 and 754 nm as the independent variables, 27 paired-samples were classified into three classes by the hierarchical cluster method. On the basis of this classification results, as the results of the Kruskal-Wallis Test showed, total salt content and pH value and organic matter content did not clearly vary by the different classes. As the results of the Median Test method showed, total salt content had the difference between the three classes. However, there are no differences of pH value and organic matter content as the classes vary. Finally, the linear regression models between the first derivative spectra and total salt content and pH value were built.
