Preparation method of green plant immersed specimens

Abstract

The invention provides a preparation method of green plant immersed specimens. The method comprises the following steps: (1) treating native plants, pretreating the collected native plants, then removing visible solid purities on the plants; (2) fixing the plants by immersing the disinfected and washed plants into a fixing solution for carrying out destruction and fixation, completing fixation when the color of the plant material is turned from green to yellow or even brown and is finally returned to green, and taking the plants out instantly; (3) preserving the plants by immersing the plantsafter completing fixation in the step (2) into a specimen bottle filled with a preservation solution, sealing and preserving to complete preparation of the plant specimens. The prepared immersed specimens have the characteristics that the primary color can be stably retained for a long time, and the plant specimens are long in preservation time, are not easily rotten and do not easily go bad.

Description

technical field [0001] The invention relates to a method for preparing a plant specimen, in particular to a method for preparing a green plant soaked specimen. Background technique [0002] Plant specimens are a form of preservation of living plants. You can visually observe the living plants at any time, understand the shape and color of plants, and store plant specimens in real time for future observation, research and collection. It is widely used in medicine Collection, teaching and scientific research. Among them, the effect of soaking specimens from plants is the best, which can best reflect the original characteristics of plants and can preserve the original colors of plants. [0003] The general steps of the preparation method of the traditional plant soaked specimen are pretreatment, disinfection, fixation and preservation. Among them, the traditional plant soaking specimen first trims the plants and then disinfects and cleans the plants. The general disinfection ...

Problems solved by technology

[0004] But, in the preparation method process of above-mentioned herbarium, there are many problems

For example, 1. The branches and leaves of many plants are relatively loose and brittle after being collected and desoiled, and the integrity of plant specimens and the preservation of their original identification characteristics are one of the keys to plant specimens. It is easy to affect the integrity of plant specimens; 2. In the current fixation and preservation process of plant specimens, most of them will use formaldehyde to fix and preserve them. Because formaldehyde is volatile, toxic and harmful to human body, it has reproductive toxicity, mutagenicity and carcinogenicity. , it is very easy to cause a safety impact on the human body, and it is the cause of many diseases; 3. The plant-infused specimens made by traditional methods will often rot and deteriorate after being sealed in specimen bottles for 1 to 2 years, which is not conducive to the preservation of the original plants. Preservation, can not meet the needs of scientific research, teaching and practical application
