Abstract
The invention relates to a diagnostic method and system for drip irrigation cotton with nitrogen nutrient deficit. First, the sensitive leaf layer of cotton is determined according to the growth stage of cotton, and the spectral reflectance and biomass of each functional leaf in the sensitive leaf layer are collected to calculate average spectral reflectance of the sensitive leaf layer and the maximum leaf biomass. Then, the critical nitrogen concentration was calculated according to the maximum leaf biomass. Finally, the nitrogen nutrition index of cotton is calculated according to the nitrogen concentration and the critical nitrogen concentration. The nitrogen nutrition index is used to characterize the abundance and deficiency of nitrogen nutrition in cotton, so as to determine the abundance and deficiency of nitrogen nutrition in cotton, which can reduce the calculation amount of nitrogen nutrition index, diagnose the abundance and deficiency of nitrogen nutrition in drip irrigation cotton.
