Abstract

The invention provides a method and a system for detecting pesticide residue of vegetables. The method comprises the steps: acquiring first reflection spectrum data of vegetables to be detected; calculating a pesticide residue index of the vegetables to be detected according to a pre-established vegetable pesticide residue index model and the first reflection spectrum data; determining the degree of pesticide residue of the vegetables to be detected according to the pesticide residue index and a preset threshold value. According to the method and the system for detecting the pesticide residue of the vegetables, the degree of pesticide residue of the vegetables is determined through the reflection spectrum information of the vegetables to be detected, the pre-established pesticide residue index model and the preset threshold value, so that real-time nondestructive examination is achieved, the detection process is safe, convenient and quick, and the detection result is high in accuracy.

Description

technical field [0001] The invention relates to the technical field of spectral analysis, in particular to a method and system for detecting pesticide residues in vegetables. Background technique [0002] In recent years, due to the excessive use of chemical pesticides by vegetable farmers in the process of preventing and controlling vegetable diseases and insect pests, the amount of pesticide residues in vegetables has become higher and higher, directly endangering vegetable exports and the health of the people. Moreover, food poisoning incidents caused by excessive residues of various pesticides in vegetables have been frequently reported. Therefore, how to detect whether there are excessive pesticide residues in vegetables on the market is an urgent problem to be solved in current vegetable production. At present, governments around the world are also continuously strengthening the detection of pesticide residues. The requirements for the sensitivity and efficiency of pe...
