[0002] With the development of modern agriculture, refined management technology has gradually been applied to the process of crop planting, especially in the fertilization process. Precision fertilization can effectively improve fertilizer utilization, reduce resource waste, and increase crop yields. However, traditional fertilization methods usually rely on manual labor or large-scale mechanical equipment, which is not only labor-intensive, but also difficult to accurately adjust according to the needs of crops at different growth stages. In addition, there are significant differences in the absorption efficiency of fertilizers for crops at different heights and growth densities. Traditional fertilization methods often ignore these differences, resulting in excessive or insufficient fertilization, which in turn affects crop growth and the overall yield of farmland;

[0003] In recent years, drones have been increasingly used in agriculture, especially in spraying pesticides and fertilizers. Low-altitude drones have the characteristics of high flexibility, wide coverage, and fast operation speed. However, most existing drone fertilizer spraying systems use a fixed height and range spraying method, which cannot be used for fine fertilization according to the height and density of different crops, resulting in low fertilizer utilization rate.
