Chlorophyll plays a crucial role in the photosynthesis of plants. Its content is an important indicator of plant nutrition stress, photosynthetic capacity, and growth conditions

Chlorophyll content measurement can be used to monitor the growth and development conditions of plants, thereby making scientific guidance of cultivation, fertilization and management, ensuring the good growth vigor, and enhancing crop quality and yield. As a result, it is of great significance for precision agriculture and forestry.
