Problems solved by technology

[0006] 1. None of the methods disclosed in the above patents and documents can meet the requirements of color retention and mildew resistance at the same time
Although the invention of "A Method for Preparing Specimens of Cured Leaves with Primary Color of Tobacco Leaf" (Application No. CN201110209776) has done a good job in color preservation, the method is relatively deficient in anti-mold and has limitations in material selection.
[0007] 2. There is a common problem of cumbersome production process
[0008] 3. High requirements on the environmental conditions in the production process
[0009] 4. Both the method of "quickly making wax leaf specimens with a microwave oven" and the specimen making method disclosed in "Using Ultrasonic Method to Make Plant Wax Leaf Specimens" (application number CN85105503) have the defect that the operating space is limited
[0010] 5. Varnish was used in "A liquid-film-enclosed method for making natural-color waxed leaf specimens of plants" (application number CN201110330787), and latex was used in the "rapid pressing method of natural-colored plant waxy leaf specimens" (application number CN90109901). The above chemical products There are security issues

Abstract

The invention relates to a method for preparing herbarium specimens. The method comprises the following steps: (1) collecting plant specimens and routinely preprocessing the specimens; (2) preparing a Chinese herbal medicine solution; (3) scalding the preprocessed fresh specimens in the Chinese herbal medicine solution under 10-100 DEG C for 1 second to 10 minutes; (4) drying the scalded specimens in air or absorbing all water from the scalded specimens, and flatly pressing in a specimen clip; (5) carrying out low-temperature airing treatment on the prepared specimens for 5-160 hours at the temperature of 5-20 DEG C. According to the method, the Chinese herbal medicine solution is directly utilized to scald the fresh plant specimens, has very good effects of killing bacteria and insects and preventing molds, and can be used for killing insect eggs and spores attached to the surfaces of plants to ensure that the plants are relatively bright in color. In addition, the low-temperature airing treatment can ensure that the plants can keep the original color and are prevented from being mildewed, so that the specimens can be stored for a relatively long time by using the method.

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. Background technique [0002] Wax leaf specimens, also known as pressed specimens, are a type of dried plant specimens. It is of great significance to the work of plant classification. The rapid development of plant classification in the second half of the 16th century was largely caused by the new technology of wax leaf specimens. Wax leaf specimens allow botanists to check specimens collected from different regions throughout the year. At present, some large herbariums often collect more than one million wax leaf specimens, and botanists use these specimens for description and identification. Collect a leafy branch of a plant with flowers and fruits, or a whole plant with flowers or fruits, flatten and dry it in a specimen holder, and stick it on table paper to form a wax leaf specimen. [0003] In the production proc...
