This application discloses a multi-task parallel automatic observation method for crop physiological and structural phenotypic parameters, including: building a spectral observation system and performing radiation calibration on it to obtain radiation calibration coefficients; The solar incident spectrum and the crop canopy reflectance spectrum at different points are continuously observed to obtain the time-series spectral observation data; the spectral observation data is processed according to the radiation calibration coefficient to obtain the solar incident spectrum and the crop canopy reflectance spectrum at different points According to the radiance value of the solar incident spectrum and the radiance value of the crop canopy reflection spectrum at different points, the physiological and structural time-series phenotype parameters of each observation object are inverted in parallel. The application can obtain the solar incident spectrum and the crop canopy reflectance spectrum at different points in parallel, and invert the physiological and structural time-series phenotype parameters of the crop canopy at different points.
Description
technical field [0001] This application relates to the technical field of acquisition of vegetation remote sensing parameters, in particular to a multi-task parallel automatic observation method for multi-point crop physiological and structural phenotypic parameters. Background technique [0002] Plant phenotype is an important bridge to study the interaction between plant genes and the environment, is the core means of serving crop genetic breeding and cultivation management, and is of vital strategic significance for ensuring germplasm resources and food security. In the process of achieving the goals of high yield, high quality and high resistance of crops, high-throughput monitoring of crop structure and physiological phenotypes is a current research hotspot. At present, the methods for obtaining crop structural phenotypes are relatively mature, but the methods for time-series observation of them are relatively lacking, and the biological significance of most structural ...
