Research background and significancePrecision agriculture basic research: By capturing the subtle differences in crop spectra, we deeply explore the relationship between crop physiological and biochemical processes (such as chlorophyll synthesis and water transport) and spectral characteristics, and provide data support for establishing more accurate crop growth models. Efficient use of agricultural resources: Quantify the demand and utilization efficiency of crops for water, fertilizer, and light energy, help formulate resource (such as water resources, fertilizer) optimization allocation plans, and promote sustainable agricultural development.Equipment application introduction1. Crop physiology and growth status monitoringNutrient (nitrogen, phosphorus, potassium) content estimation: Using the spectral characteristics of visible light-near infrared bands (such as red edge bands), invert the nitrogen content of crop leaves to guide precise fertilization. For example, the reflectivity ...
