Abstract: Based on the overview of the nutrition diagnosis of plant nitrogen, main contents of the chemical diagnosis and the non-destructive measurement were summarized, the principles, merits, shortcomings and current status of the nitrate quick test, the chlorophyll meter and the remote sensing in the nutrition diagnosis of crop nitrogen and the recommendation of nitrogen fertilizer were analyzed. At last, the combination of chlorophyll meter and the remote sensing, the use of chlorophyll fluorescence technique in the nutrition diagnosis of plant nitrogen, and the assessment of the forest ecosystem health and the evaluation of ecosystem services by the nutrition diagnosis of plant nitrogen, were discussed.
