Preparation method of plant unbleached impregnated specimen

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...

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
