Problems solved by technology

[0004] The purpose of the present invention is to provide a preparation method for preserving soaked specimens of tropical plants. Combining the environment in which tropical plants grow and the characteristics of physiological changes of the plants themselves, the fixative and preservation solutions are combined, which can effectively solve the problem of the color and luster of existing soaked specimens. Problems such as short storage time and incomplete plant form are simple, easy to implement, low in cost, long in storage time, strong in three-dimensionality, and can effectively preserve the original form of the original plant, greatly improving the quality of teaching and scientific research

Abstract

The invention relates to a method for preparing a tropical plant preserving humid preparation. The method comprises the following steps of trimming and cleaning a collected fresh preparation body, sterilizing and soaking the preparation body in stationary liquid, taking out and cleaning the preparation, trimming the preparation for the second time, fixing the trimmed preparation onto a glass plate, sealing the preparation in a preparation bottle filled with preserving liquid and storing the preparation in a dark place at the temperature of 20-25 DEG C, wherein the stationary liquid is prepared in the following steps of adding a copper sulfate solution, boric acid, a sulphurous acid solution, a magnesium chloride solution, an ethanol solution and a magnesium chloride water solution into a formaldehyde solution, fully and uniformly mixing; the preserving liquid is prepared in the following steps of adding the sulphurous acid solution, formaldehyde, glycerol and the magnesium chloride solution into purified water and then fully and uniformly mixing. The method is simple in process and capable of quickly sterilizing, fixing and storing an original fresh plant product, can be used for effectively storing original shapes of multiple organs of an original plant, has the characteristics of low cost, long storage time, high stereoscopic sensation and the like, and is favorable for improving the quality of teaching and scientific research.

Description

technical field [0001] The invention belongs to the technical field of plant specimen production, and relates to a production method of soaked specimens of original plants, in particular to a production method of preserved tropical plant soaked specimens. Background technique [0002] The production of plant specimens occupies a very important position in medical collection, teaching and scientific research, and is also essential. When a certain plant is involved in class or research, it is best to have a living body of this plant in order to deepen understanding . However, most plants are regional and seasonal, and living plants cannot be obtained at any time, which affects teaching and scientific research. The use of plant specimens allows researchers to observe plants visually at any time without being restricted by regional and seasonal characteristics. At the same time, plant specimens are also convenient for preserving plants for re-observation and research in the fut...
