Abstract
The present disclosure relates to a method and system for the in-situ detection of cadmium chelates in a plant. The method includes: preparing cadmium chloride and phytochelatin (PC) 2 samples with different concentrations; using terahertz time-domain spectroscopy (THz-TDS) to determine a terahertz (THz) reflection image for the cadmium chloride and PC 2 samples; building a cadmium chloride content detection model according to first spectral data; building a PC 2 content detection model according to second spectral data; determining an optimal mixed sample according to the cadmium chloride content detection model and the PC 2 content detection model; building a Cd—PC2 content detection model according to the optimal mixed sample; and using the Cd—PC2 content detection model to determine a cadmium chelate content in a to-be-tested plant. The present disclosure can quickly and in-situ detect the heavy metal accumulation capacity of a plant.
