Problems solved by technology

[0002] Plant specimens dipped in primary colors not only play a very important role in teaching and scientific research, but also have important value in specimen display, display and artistic appreciation. The chemical composition contained in the body is complex, and its chemical change law is difficult to grasp, which brings great difficulties to the production of primary color plant soaked specimens
At present, there are the following main problems in the traditional preparation of primary color specimens of plants: First, some toxic reagents such as formalin and sulfurous acid are often used in the preservation solution. These substances are unstable, volatile, and harmful to the human body; Fixatives and preservation solutions for preserving plant material of different colors, such as green herbarium fixation and preservation solutions, red herbarium fixation and preservation solutions, purple herbarium fixation and preservation solutions, white herbarium fixation and preservation solutions, and Yellow plant specimen fixing solution and preservation solution, etc.; 3. These traditional methods of immersion of plant primary color specimens need to prepare numerous fixation solutions and preservation solutions, which is a lot of work, and it is often caused by excessive preparation of fixation solutions and preservation solutions. Bring a lot of waste; four, the more important point is that the branches, leaves, flowers, and fruit colors of any plant are often not consistent, and it cannot be preserved as a whole by traditional methods.
Generally speaking, the traditional herbarium infusion method is narrow, impractical and expensive

Embodiment 1

[0030] The present invention is an economical and environmental-friendly plant primary-color dipped sample preparation method used for dipping and preserving yellow Chinese rose specimens. The specific steps are:

[0031] Step 1, collection and pretreatment of yellow Chinese rose

[0032] Select yellow rose plant specimen materials with normal growth and no pests and diseases, and cut off diseased and dead leaves, incomplete flowers, and excessive branches and leaves. It is required to preserve the integrity of yellow roses as much as possible, and retain its classification and identification characteristics. Wash the fresh yellow Chinese rose material with tap water, disinfect with 70% alcohol for 5 min, and soak and rinse with distilled water twice.

[0033] Step 2, fixative kill and fix

[0034] 1) Preparation of fixative

[0035]First weigh 15 g of ketone acetate and dissolve it in 250 mL of 50% acetic acid by volume, then add 250 ml of distilled water to dilute, then ad...

Embodiment 3

[0057] A kind of preparation method of the soaking specimen of environmental protection plant primary color of the present invention is used for the process method of soaking preservation of red carnation specimen, and concrete steps are:

[0058] Step 1. Collection and pretreatment of red carnation specimen materials

[0059] Choose red carnation specimen materials that grow normally and are free from diseases and insect pests, and cut off diseased and dead leaves, incomplete flowers, and excessive branches and leaves. It is required to preserve the integrity of the red carnation specimen as much as possible, and to preserve its taxonomic identification characteristics. After washing the fresh red carnation specimens with tap water, disinfect them with 70% alcohol for 5 min, then soak them in distilled water and rinse them 3 times.

[0060] Step 2, fixative kill and fix

[0061] 1) Preparation of fixative

[0062] First weigh 15 g of ketone acetate and dissolve it in 250 m...

Embodiment 4

[0070] The preparation method of an environment-friendly plant primary-color soaked specimen of the present invention is used for re-colored plant specimens, that is, a process for simultaneously soaking and preserving red rose flowers and yellow carnations, and the specific steps are:

[0071] Step 1. Collection and pretreatment of red rose and yellow carnation specimen materials

[0072] Choose red rose flowers and yellow carnation specimen materials that grow normally and are free of diseases and insect pests, and cut off diseased and dead leaves, incomplete flowers, and excessive branches and leaves. It is required to preserve the integrity of the specimen as much as possible, and retain its taxonomic identification characteristics. After washing the fresh red rose and yellow carnation specimens with tap water, they were disinfected with 70% alcohol for 5 min, and then rinsed with distilled water for 3 times.

Abstract

The invention provides a preparation method of a plant unbleached impregnated specimen. In the invention, the fixative of the operation process adopts a composite biocidal formula and simplifies the fixing and biocidal procedures, and the operation is simple; and the preservation solution for preserving the plant specimens adopts nontoxic and inexpensive biological extracts, such as garlic extract, ginger extract, carboxylation chitosan and the like, and solves the problem of environmental pollution when preserving and storing the plant specimens. The preparation method of invention can be applied to the impregnation and preservation of monochromatic plants, such as green, yellow, red, white plants and the like, multi-color plants and whole plant specimen, and provides a novel way for preparing the plant unbleached impregnated specimens.

Description

Technical field: [0001] The invention relates to a method for preparing a specimen, in particular to a method for preparing a specimen soaked in primary colors of plants. Background technique: [0002] Specimens soaked in primary colors of plants not only play a very important role in teaching and scientific research, but also have important value in specimen display, display and artistic appreciation. Due to the complex chemical components contained in plants, it is difficult to grasp the law of chemical changes. The production of herbarium-infused specimens in primary colors poses great difficulties. At present, there are the following main problems in the traditional preparation of primary color specimens of plants: First, some toxic reagents such as formalin and sulfurous acid are often used in the preservation solution. These substances are unstable, volatile, and harmful to the human body; Fixatives and preservation solutions for preserving plant material of differe...
