The invention discloses a histochemistry method capable of fast displaying a latex vessel of a bark of a rubber tree. The histochemistry method comprises the following steps: a) copping the bark of the rubber tree into section tissue blocks with the dimension of 0.5cm (length) * 0.5cm (width) and placing the section tissue blocks into a centrifugal tube containing stationary liquid; b) opening a lid of the centrifugal tube, placing the centrifugal tube into a glass dryer connected with a vacuum pump and exhausting air for 1-2min; c) exchanging fresh stationary liquid and rinsing for 3 times by buffer solution after fixing for 4-6h at room temperature, wherein the rinsing lasts 30min at each time; d) transiting the material in the step c) to protective agents with different concentration gradients from the stationary liquid; e) embedding the material in the protective agent with the highest concentration in the step d) into an OCT (Ornithine Carbamyl Transferase) embedding agent, placing the material on a refrigeration platform at -20 DEG C and condensing for 20min; f) taking out the material in step e) and sectioning the material by a conventional frozen section method; g) sticking sections by a common glass slide at room temperature; h) mounting the sections with a mounting medium and observing the sections by a fluorescence microscope. The histochemistry method disclosed by the invention has the advantages that the operation is simple, labor and land are saved, the repeatability and the universality are good, and batch screening can be realized.
