Manufacturing method for liquid film closed type plant primary-color herbarium specimens

Abstract

The invention discloses a manufacturing method for liquid film closed type plant primary-color herbarium specimens. The manufacturing method comprises the procedures of dehydrating the specimens, spraying, drying and storing, wherein the specimen dehydration procedure is to clear leaves of the collected fresh plants, remove dust and dirt and absorb water by using absorbent paper or perform plasticizing dehydration by using polyethylene glycol; the spraying procedure is to spray varnish serving as a film medium onto the surfaces of the plant leaves, so that one layer of paint film covers the surfaces of the leaves uniformly; the painted leaves are placed on a rack and the varnish film is dried; and the specimens which are inspected to be qualified are stored. The varnish is sprayed on the herbarium specimens based on a paint film-forming technological principle, so that one layer of paint film is adhered to and wrapped on the surface of each specimen; and each herbarium specimen is subjected to film sealing by drying the surface of each specimen. The adopted varnish is transparent and colorless; and after the film is sealed, the light transmittance is high, the original state of the specimen is not damaged and destroyed and the original color can be observed. After the varnish is formed into the film, air can be isolated, so color fading and deterioration are avoided, the storage condition is simplified and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of plant specimen production, and in particular relates to a method for producing a liquid-film-enclosed plant natural-color wax leaf specimen which not only maintains the original color of the plant wax leaf specimen, but also can be stored for a long time by using liquid film-forming technology to seal the specimen. Background technique [0002] In the prior art, wax leaf specimens of plants are important carriers for teaching and scientific research. At present, there are mainly four methods of preservation: sealing in a glass box, pasting with table paper, plastic sealing, and embedding. Sealing in a glass box and sticking table paper are the most commonly used methods, which are suitable for the preservation of flat and three-dimensional plant wax leaf specimens. The preservation method is simple and easy, but the disadvantage is that the preservation conditions are high. The plastic sealing method, suc...

Problems solved by technology

But the disadvantage is that the temperature is high when pressing the film, and the improper time control will easily cause the specimen to change color and break, and it is only suitable for the preservation of the plane plant wax leaf specimen.

The embedding method mainly uses plasticizers (Chinese invention patent ZL 01107910.X), crystal glue (Chinese utility model patent ZL 200920140004.4), water-soluble gum (Chinese invention patent publication number CN101935447A) and other easily solidified materials to embed specimens , solidification, this method is suitable for the preservation of flat and three-dimensional plant wax leaf specimens, especially for the preservation of three-dimensional specimens, and has the advantages of long storage period and convenient use. The disadvantage is that the sealing process is complicated, the cost is relatively high, and the materials are not obtained Convenience, limited range of applications
