Manufacturing method of magnoliaceae color-retaining specimen

The invention discloses a manufacturing method of a magnoliaceae color-retaining specimen. The method can shorten the color retention time in the manufacturing process, so that the specimen is long in color retention and preservation time. The method comprises the following steps: (1) putting magnoliaceae into ethyl alcohol to be soaked for 20-40 min; (2) adding copper acetate powder into 50% glacial acetic acid until the solution is saturated, and diluting the solution to 3 times to obtain a color-retaining solution; (3) putting the magnoliaceae obtained in the step (1) into the color-retaining solution, performing heating and soaking until the color is greened again, and then soaking and cleaning the magnoliaceae with water; and (4) putting the magnoliaceaeon a water-absorbing towel to absorb surface moisture, putting the magnoliaceae into water-absorbing paper, pressing the magnoliaceae by using a specimen holder, drying the magnoliaceae by using a specimen dryer to obtain a magnoliaceae specimen, and perf
