Technical Field

The invention relates to the field of agricultural product detection, in particular to a quick agricultural product detection device.

Background

In agricultural production, pesticides for killing insects, bacteria and harmful animals (or weeds) are often applied to ensure and promote the growth of plants and crops. However, due to the use of a large amount of pesticides, the applied pesticides remain on the produced agricultural products after the pesticides are applied to crops, and various diseases caused by pesticide residues become serious day by day, so that the life health of human beings is threatened unprecedentedly. Research shows that after long-term consumption of fruits and vegetables with pesticide residues, a certain amount of residual pesticide can be deposited in human bodies, and the pesticide can reach joints of each neuromuscular system through blood circulation to seriously damage neurons and even cause central nerve death, so that the immunity of each organ of the bodies is reduced, and various diseases are caused to outbreak.

In the prior art, the main methods for detecting pesticide residues in agricultural products are as follows:

a dissolution detection method: the agricultural products are placed in a container filled with a dissolving solution, the pesticide left on the agricultural products is dissolved in the dissolving solution, and the dissolving solution is collected for analysis and detection. The detection method can not damage the detected agricultural products and can carry out comprehensive detection, but a great deal of time is consumed for dissolving the residual pesticide on the agricultural products, and the agricultural products are also accelerated to be rotten after being soaked in water for a long time.

Mashing detection method: the agricultural products are smashed, and then the smashed juice and vegetables are collected for analysis and detection. The detection method is high in detection speed, but can damage detected agricultural products, waste occurs in the detection process, and the detection method is only suitable for sampling detection and cannot carry out comprehensive detection.
