Abstract

The invention provides a making method of a herbarium specimen. The method includes: collection treatment, pressing finishing, drying treatment, freezing treatment and other steps. The specific stepsinclude: collecting specimens, pretreating the specimens by a conventional method, stacking the specimens in a specimen holder by absorbent paper, corrugated paper and a moisture absorbent, carrying out constant-temperature color-retaining shaping for 18-24h in an environment of 25-35DEG C, replacing the absorbent paper, and then carrying out constant-temperature drying for 12-24h in an environment of 55-65DEG C, fixing the specimens on graph paper, then conducting low temperature freezing for 12-24h, and placing the specimens to room temperature so as to obtain the herbarium specimen. The method provided by the invention has faster specimen making speed, shortens the time than the conventional pressing method, also maintains the original color of plant and prevents insect damage, therefore the making method of a herbarium specimen provided by the invention can enable longer preservation of the specimen.

Description

technical field [0001] The invention relates to the field of preparation of plant specimens, in particular to a preparation method of wax leaf specimens. The preparation method comprises the steps of collecting, pressing, drying, freezing and the like. Background technique [0002] Wax leaf specimens, also known as pressed specimens, are a type of dried plant specimens. Collect a leafy branch of a plant with flowers and fruits, or a whole plant with flowers or fruits, press and dry in a specimen holder, and stick it on table paper to form a wax leaf specimen. Wax leaf specimens are important materials for teaching and scientific research, and are widely used in scientific research, teaching, drawing, exhibition, viewing, etc., and are of great significance to plant classification. [0003] Chinese patent (application number CN200410011050) discloses a "preparation method of plant wax leaf specimen". Chinese patent (Application No. CN90210953) discloses two inventions of "...
