Method for efficient color retention, insect prevention and corrosion prevention of plant specimens

Abstract

The invention relates to a method for efficient color retention, insect prevention and corrosion prevention of plant specimens. The method comprises the steps of collecting fresh branches, correcting the specimens, wrapping the specimens with absorbent paper, pressing the specimens with an iron, sterilizing the specimens for a short time by using high-pressure steam, dipping the specimens in stationary liquid and preserving liquid, sealing with mixed molten wax, binding and the like. According to the method, branches and leaves are made into specimens in a split mode; according to the cell permeability and body color differences of the leaves and the branches, a copper sulfate solution with a concentration of 2.8-3.2 wt% is used as the stationary liquid for the branches, sulfurous acid with a concentration of 2.8-3.2 wt% is used as the preserving liquid for the branches, and the branches are soaked in a specimen bottle for preservation; and for leaves, the leaves are soaked in alcohol with a concentration of 14-16% for 3-4 days, then sulfurous acid is added until a concentration is 15% after spots appear on the surfaces of the leaves, then the leaves are soaked for 1-2 days, then the leaves are washed with distilled water and soaked in alcohol with a concentration of 19-22% for hardening and bleaching until spots are eliminated, and the leaves are soaked in a specimen bottle for preservation with a mixed solution containing 1-2% of sulfurous acid and 1-2% of glycerinum as the preserving liquid. The specimens prepared by the method have the characteristics that the color of the specimens is bright, the stereoscopic impression of the specimens is strong, the forms of the specimens are vivid, the morphological characteristics of plants are convenient to observe, and the identification of the 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...

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.
