Abstract: In this paper, exploration and improvement to the primary technical section was discussed base on the material of various leaves and roots from several plants including trees, bush and liane. During staining, Turpentine was used as transparent agent, and arabic gum was employed as adhesive. The safranin and fast green were binatively utilized in the staining process. A wealth of results showed that the ontamination from xylene could be avoided via our staining method, and the marked decline of pollution to environment was significant. Furthermore, the effectiveness and quality of the section were significantly improved with a shorter duration.
