Zusammenfassung:The invention provides a coffee tree irrigation method and system based on hyperspectrum. The method comprises the following steps: establishing a coffee tree crown hyperspectral reflectivity data set; obtaining the moisture content of the leaf sample and the moisture content of the soil sample; taking the hyperspectral reflectivity data after feature extraction as input, taking the water content of the coffee tree leaves as output, and establishing an inversion model of the water content of the coffee tree canopy leaves; and establishing an inversion model of the coffee tree soil moisture content based on the vegetation index. And acquiring irrigation decision information of the coffee tree based on the inversion model. According to the method, the inversion model between the hyperspectral information and the leaf moisture content and between the vegetation index and the soil moisture content is established, the moisture demand condition of the coffee tree is rapidly and nondestructively obtained through the
