Problems solved by technology

Although this method produces plasticized specimens, the pretreatment time of the specimens is long and the soaking time for plasticization is long (5-20 days), and the production of plant specimens has not been studied in depth, so it cannot be directly used for the production of plant plasticized specimens.

Embodiment 1

[0043] Collect Coptis chinensis plants with normal growth and no pests and diseases as specimen materials, and cut off diseased and dead leaves, incomplete flowers and excessive branches and leaves. It is required to preserve the integrity of the plant as much as possible and retain its taxonomic identification characteristics. Wash the collected fresh Coptis chinensis with tap water, soak and rinse with distilled water for 3 times, and arrange the leaves and flowers. Heating the pretreated coptis plants in 10% copper acetate aqueous solution until the plants first turn yellow-green and then green, and then rinse the plants with clear water. Put the color-fixed plants into 10%, 30%, 50%, 70%, and 100% plasticizing solution (PEG-400) for gradient soaking, and the soaking time is 6, 10, 15, 15, and 20 hours respectively . Remove after soaking and rinse off residual solution with clean water. The plasticized specimens were blown and heated at 40°C until the plants were complet...

[0045] Collect Coptis chinensis plants with normal growth and no pests and diseases as specimen materials, and cut off diseased and dead leaves, incomplete flowers and excessive branches and leaves. It is required to preserve the integrity of the plant as much as possible and retain its taxonomic identification characteristics. Wash the collected fresh Coptis chinensis with tap water, soak and rinse with distilled water for 3 times, and arrange the leaves and flowers. Heating the pretreated coptis plants in 36% copper acetate aqueous solution until the plants first turn yellow-green and then green, and then rinse the plants with clear water. Put the color-fixed plants into 20%, 40%, 60%, 80%, and 100% plasticizing solution (PEG-400) for gradient soaking, and the soaking time is 8, 10, 12, 12, and 15 hours respectively . Remove after soaking and rinse off residual solution with clean water. The plasticized specimens were blown and heated at 40°C until the plants were complet...

Embodiment 3

[0047] Collect Coptis chinensis plants with normal growth and no pests and diseases as specimen materials, and cut off diseased and dead leaves, incomplete flowers and excessive branches and leaves. It is required to preserve the integrity of the plant as much as possible and retain its taxonomic identification characteristics. Wash the collected fresh Coptis chinensis with tap water, soak and rinse it twice with distilled water, and arrange the leaves and flowers. Heating the pretreated coptis plants in 15% copper acetate aqueous solution until the plants first turn yellow-green and then green, and then rinse the plants with clear water. Put the color-fixed plants into 20%, 40%, 70%, 85%, and 100% plasticizing solution (PEG-500) for gradient soaking, and the soaking time is 6, 12, 16, 16, and 20 hours respectively . Remove after soaking and rinse off residual solution with clean water. The plasticized specimens were blown and heated at 40°C until the plants were completely...

Abstract

The invention relates to a preparation method of a plant plasticized specimen. The preparation method comprises the steps: sequentially soaking plants after color fixing into five solutions, wherein the mass fractions of polyethylene glycol of the five solutions are sequentially increased, the difference value between the mass fraction of the polyethylene glycol of the two adjacent solutions is 15-30 DEG C, and the mass ration of the polyethylene glycol of the final solution is 100 percent; controlling each soaking time within 5-20 hours, wherein the subsequent soaking time is no less than that of the prior soaking. With the adoption of the preparation method, as the polyethylene glycol is adopted to carry out permeation and plasticizing on the plant specimen, a plasticizing agent is cheap and easily obtained, and the plasticizing period is short. Particularly, a coptis chinensis plasticized specimen prepared by virtue of the preparation method keeps the primary posture and color, is not easy to discolor and has the artistry; in addition, in the storage process, the intrinsic green color of the coptis chinensis plasticized specimen is not influenced by environment factors of illumination, humidity, temperature and the like, and the preservation time of the coptis chinensis plasticized specimen is long.

Description

technical field [0001] The invention belongs to the technical field of preservation of animals and plants or their parts, and in particular relates to a method for making plasticized plant specimens. Background technique [0002] Plant specimens, especially medicinal plant specimens, provide a three-dimensional cognitive space and a visual learning model for learning Chinese medicine knowledge. They not only play an important role in teaching and scientific research, but also play an important role in specimen display, display and artistic appreciation. important value. Due to the complex chemical components contained in plants, it is difficult to grasp the law of chemical changes, which brings great difficulties to the research on the preparation methods of primary color plant specimens. [0003] Preparation methods of medicinal plant specimens include pressing method, dipping method and so on. Among them, the preparation method of pressed specimens is the most convenient...
