HEAVY METAL SAFETY DIAGNOSIS SYSTEM AND METHOD FOR CROP ASSOCIATED WITH SELENIUM AND CADMIUM

摘要

Provided are a heavy metal safety diagnosis system and method for a crop associated with selenium and cadmium. The system comprises: a UI module for inputting related parameter data and displaying a calculation resu a processing module for calculating the heavy metal cadmium content in a crop according to the related parameter data and evaluating the safety of the heavy metal content in the crop, wherein related parameters comprise the soil available selenium content, soil pH, soil electrical conductivity, soil organic matter content, soil heavy metal cadmium content, and soil extractable heavy metal cadmium content; and a management module for inputting, after receiving the related parameter data, the related parameter data into a relational model for calculation and evaluating the safety of the heavy metal content in the crop, and transmitting an evaluation result to the UI module for display. By taking the soil heavy metal cadmium content, the available selenium content and various physicochemical properties as conditions, the heavy metal content in a crop is calculated and a safety evaluation is made, which is of great significance to safe production of the crop.
