Abstract: Nitrogen is one of the essential nutrient elements for crop growing and development, 70%-80% of the nitrogen in plant leaves is found in chloroplast. So the chlorophyll content can reflect the nitrogen nutrition status in plants. The study introduced the traditional detection technology of chlorophyll in plants, pointed out the problems in the promotion and application, summarized the research progress on the nondestructive diagnostic technique of chlorophyll in plant at home and abroad, and analyzed the significance of nondestructive diagnostic technique of chlorophyll in diagnosing the nitrogen nutrition in plants and the fertilization recommendation. In conclusion, the chlorophyll analysis technology is more suitable for application, and the nondestructive diagnostic technique of chlorophyll based on optical diffuse reflectance theory is very promising.
