Description

Technical Field

[0001] The invention relates to the technical field of specimen preparation, in particular to a plasticizing liquid for algae plants and application of the plasticizing liquid in preparing algae plant specimens. Background Art

[0002] At present, green plants are mostly preserved by pressing, traditional immersion, plastination and other plant specimen preparation methods. Among them, pressed specimens are easy to fall off and fade, have a single shape and are extremely easy to damage; the traditional immersion method specimens retain color close to the original color, but its preservation solution containing formaldehyde has defects such as volatility, toxicity, and irritating odor; plasticized specimens prepared by the plastination method are not easy to deteriorate, have diverse forms and are pollution-free, and are very popular, but they have the defects of poor color retention and color retention time, and contain a certain amount of formaldehyde, which is toxic. Therefore, a specimen preparation method that can preserve plant morphology and color for a long time is disclosed, which has important value in teaching and scientific research, specimen display, exhibition and artistic appreciation. Summary of the invention

[0003] The purpose of the present invention is to provide a plasticizing liquid for algae plants and its application in preparing algae plant specimens, so as to solve the problem that the pressing method and the plasticizing method in the existing methods for preparing algae plant specimens cannot keep the original color of the plants for a long time, and the problem that the preservation liquid obtained by the immersion method contains the volatile toxic substance formaldehyde.

[0004] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0005] The present invention provides a plasticizing liquid for algae plants, comprising the following raw materials in parts by weight:

[0006] 50-55 parts of polyethylene glycol, 35-40 parts of methanol, 5-10 parts of glycerol, 10-15 parts of color retaining solution;

[0007] The color preserving solution is a saturated copper acetate acetic acid solution.

[0008] Preferably, the molecular weight of the polyethylene glycol is 400.

[0009] Preferably, the color preserving solution is prepared by adding copper acetate to a 50% acetic acid solution until saturated to obtain the color preserving solution.

[0010] The present invention also provides an application of the above-mentioned plasticizing liquid for algae in preparing algae specimens, comprising the following steps:

[0011] 1) The algae samples are sequentially cleaned, disinfected with alcohol, washed with water, and then immersed in a plasticizing solution for algae;

[0012] 2) After the soaking is completed, the algae sample is taken out and dried to obtain an algae specimen.

[0013] Preferably, the soaking time in step 1) is 48 to 72 hours.

[0014] Preferably, the drying temperature in step 2) is 20-28° C. and the drying time is 10-15 days.

[0015] The present invention has at least the following beneficial effects:

[0016] This application changes the original configuration of the plant plasticizing preservation solution. The polyethylene glycol in the plasticizing solution acts as a solvent and softens, methanol plays a fixing role, glycerol cooperates with the polyethylene glycol to soften, and the color preserving solution preserves the color. During use, the cell fluid in the algae plant cells is replaced with the preservation solution by soaking. The specimens after plasticizing are not easy to deteriorate, have complete morphology, excellent softness, are not easy to be damaged, are not easy to get damp, and can be placed in the air for a long time. This not only plays an important role in teaching and scientific research, but also has important value in specimen display, exhibition and artistic appreciation. BRIEF DESCRIPTION OF THE DRAWINGS
