The Red Edge Parameters Diversification Disciplinarian and Their Application in Winter Wheat
摘要
Abstract
Some red edge parameters( λ red, Min λ 6oo-72o, d λ,red, d λ min, d λ red / d λ min, ∑ d λ 680-750, and λ nir) and the relationship between these parameters and the parameters of biochemistry and biophysics of winter wheat were studied by regression analysis. The results indicated that there existed some changes in these red edge parameters in the whole growth stages,and there were strong correlations between red edge parameters and pramters of biochemistry and biophysics. Thus, the red edge parameters were found valuable for assessment of wheat parameters of biochemistry and biophysics. The λ red can be used to estimate the soluble sugar content and the chlorophyll content. The d λ red was the best estimator of total nitrogen content. LAI can be estimated by Min λ 600-720 satisfactorily.关键词
