Problems solved by technology

At present, when making wax leaf specimens of plants, it is necessary to perform dust removal, disinfection, fixation, moisture absorption and other treatments. When the specimens are stored for a long time, the specimens will turn yellow, moldy, etc., and some leaves will fall off and grow insects, especially in the In terms of color preservation, the color of wax leaf specimens after storage for a period of time is very different from that of fresh specimens.

Embodiment 1

[0035] A method for highly efficient color preservation, insect-proof and anti-corrosion of wax leaf plant specimens, specifically comprising the following steps:

[0036] (1) Collection:

[0037] Collect fresh and disease-free branches, and the collected branches need to strive for complete branches and leaves.

[0038] (2) trimming and pressing:

[0039] After the specimen is repaired, the leaves and branches are flattened, and the back side of the thicker branches is removed by blades and scissors to make them thinner. The flattened leaves and branches are sandwiched between two absorbent papers. The absorbent paper is made of high-quality straw paper. Put several layers of absorbent paper on both sides, and dry it quickly with an electric iron. When ironing, you need to repeatedly reverse the upper and lower sides of the absorbent paper so that the specimen can be dried evenly in the middle of the two absorbent papers. Iron until the leaves of the specimen are completely ...

Embodiment 2

[0053] On the basis of Example 1, in step (4), before preparing the fixative and preservation solutions, clean and disinfect the utensils, instruments, glass rods, specimen bottles (including bottle caps), etc.: various glassware used for making specimens (Beakers, measuring cylinders, glass rods, specimen bottles and bottle caps) must be washed with washing powder or decontamination powder, and rinsed repeatedly with clean water; then disinfected with 75% alcohol.

Embodiment 3

[0055] On the basis of Example 1, in step (1), remove impurities, dead branches and residual leaves from the collected specimens, after trimming, wash them with clear water, and then use 75% alcohol to disinfect the specimens, and use a rag to dip them in according to the specimens. Use alcohol to scrub all parts of the branches.

Abstract

The invention relates to a high-efficiency color-preservation, insect-proof and anti-corrosion method for plant specimens, which includes collection of fresh branches, specimen correction, iron pressing with absorbent paper wrapped, short-term high-pressure steam disinfection, fixative and preservation liquid immersion treatment, mixed melting wax sealing, binding, etc. step. The branches and leaves are made separately. According to the difference in the cell permeability and body color of the leaves and branches, the branches are soaked with 2.8-3.2wt% copper sulfate solution as the fixative solution, and 2.8-3.2% sulfurous acid as the preservation solution. Preserve in specimen bottles; soak the leaves in 14‑16% alcohol for 3‑4 days, add sulfurous acid to a concentration of 15% after spots appear on the surface and soak for 1‑2 days; wash with distilled water and then immerse in 19‑22% Hardened and bleached in alcohol until the spots disappear, the leaves are preserved in a specimen bottle with a mixture of 1-2% sulfurous acid and 1-2% glycerin as a preservation solution. The specimen produced by the invention has bright color, strong three-dimensional effect and lifelike shape, which is convenient for observing the morphological characteristics of plants, and the identification of plants is not limited by seasons.

Description

technical field [0001] The invention relates to a method for making a plant specimen, in particular to a method for efficiently preserving the color of a plant specimen, preventing insects and antisepsis. Background technique [0002] Wax leaf specimens are a kind of dried plant specimens, which collect a leafy branch of a plant with flowers and fruits, or a whole plant with flowers or fruits, and after being flattened and dried in the specimen holder, they are mounted on table paper On it, it becomes a wax leaf specimen, which is used for plant taxonomy research. At present, when making wax leaf specimens of plants, it is necessary to perform dust removal, disinfection, fixation, moisture absorption and other treatments. When the specimens are stored for a long time, the specimens will turn yellow and moldy, and some leaves will fall off and grow insects, especially in the In terms of color preservation, the color of wax leaf specimens after storage for a period of time is...
