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.
