Method for rapidly detecting pesticide residues in food

The invention discloses a method for rapidly detecting pesticide residues in food, which comprises the following steps of: during detection, respectively pouring a buffer solution and an extracting solution into a comparison reaction bottle and a test reaction bottle, and arranging a material storage tank for containing a substrate on one side of two liquid storage tanks, the two liquid storage tanks above each reaction bottle are respectively connected with the corresponding comparison reaction bottle or test reaction bottle through gate valves, the two opposite gate valves share a switch mechanism for controlling injection of enzyme liquid and a color developing agent, and the switch mechanism further controls n ml of substrate to be pre-placed into one buffer tank; after the enzyme liquid and the color developing agent are added, the switching mechanism rotates reversely and resets and stands still, the buffer tank discharges all substrates into the reaction bottles, liquid in the two reaction bottles is p
