Background
The preparation of the plant into the specimen has great significance for the plant classification work. Leaf specimens are one of the common and traditional methods for making plant specimens. The preparation method comprises collecting a section of plant with flower and fruit, or the whole plant with flower or fruit, pressing in a specimen clamp, drying, and pasting on a paper.
Typha angustifolia, Typha latifolia and the like belong to Typhaceae. The typhaceae is perennial herb, and has high economic value and ornamental value. The inflorescence or the fruit sequence of the typhaceae plant is cylindrical, and the surface of the typhaceae plant is densely covered with villi, which is one of the important characteristics of the typhaceae plant. If the traditional wax leaf specimen pressing method is used for manufacturing the specimen, the inflorescence or the fruity of the typhaceae plant is easy to break and deform, and the significance of manufacturing the plant specimen is lost. However, if the material is not pressed, the traditional indoor storage is difficult, and the material is light and soft, is easy to break and fly, and is difficult to store the inherent shape.

Preferably, the paraffin wax is melted by heating: and (3) placing the paraffin into a crucible, and heating and melting by using an induction cooker.
Further preferably, the heating temperature is 60 ℃.
Preferably, the paraffin is applied several times until the inflorescence or the infructescence of the typhaceae plant is no longer absorbed, i.e. the paraffin has completely penetrated into the interior thereof, and the application is stopped.
Preferably, the specific method of the collection trimming and drying treatment is as follows: collecting typicality and integrity inflorescence or inflorescence Typhaceae plant, cutting off excessive leaves, trimming to make it beautiful, and air drying in indoor ventilation place.
Preferably, the specific method for preserving the specimen is as follows: and (5) storing the specimen obtained in the color-preserving and mildew-proof treatment step in a ventilated and dry place.
Preferably, the color-preserving and mildew-proof treatment further comprises a pretreatment before paraffin coating, and the method comprises the following two steps:
(1) placing inflorescences or infructescence of typhaceae plants into a treating agent at 50-60 ℃ for dipping treatment for 8-12 hours, wherein the treating agent is prepared by mixing the following components in parts by weight: 3-6 parts of citric acid, 5-8 parts of sulfurous acid, 8-10 parts of acrylamide, 8-10 parts of N, N' -methylene bisacrylamide, 10-15 parts of tetramethylethylenediamine, 10-15 parts of boric acid, 30-40 parts of PEG 400and 100 parts of water;

Citric acid
The invention has the beneficial effects that:
1. the method is simple, convenient and feasible, has low cost, avoids the defect that the cylindrical typhaceae plant inflorescence is easy to break by adopting the traditional preparation method of the cured leaf specimen, and well preserves the inherent shape.
2. The paraffin has low price, is harmless to human bodies, can play a good role in fixing the specimens in the preservation process, and also has the functions of preventing moisture, alleviating worm damage, facilitating preservation and prolonging the service life of the specimens.
3. If the paraffin is directly coated on the surfaces of inflorescences or infructescence of typhaceae plants, the paraffin is easy to fall off in dry air, and the service life of a specimen is further influenced; in the invention, the paraffin penetrates into the typhaceae plant by a method of coating the inflorescence or the infructescence of the typhaceae plant layer by layer after baking, thereby effectively avoiding the paraffin from falling off.
4. The specimen is also pretreated before being coated with paraffin wax to play a role in color retention and mildew resistance, and tests prove that the specimen can keep good color and luster for more than 5 years, and has no discoloration and mildew.

Test example 1
Taking the inflorescence (dark brown) of Typha angustifolia as an example, the Typha angustifolia in the same area of the map is collected at the same time, and Typha angustifolia with the size, shape and color close to the inflorescence is selected and the specimens are prepared by the methods of examples 1-5 and comparative examples 1-2 respectively. And (3) placing the obtained specimen in a room with the temperature of 20-25 ℃ and the humidity of 50-60% for storage, wherein the examination time is five years. The results are shown in Table 1.
TABLE 1 color retention Effect examination results
As can be seen from Table 1, in comparative example 1, paraffin is directly coated on the surface of the inflorescence, and the paraffin easily falls off in dry air, so that the protection of the paraffin is lost, and the color of the inflorescence is obviously faded soon. Comparative example 2 omits the pretreatment step before paraffin coating, and the color retention effect is significantly slightly poor. The specimens prepared in the embodiments 1 to 5 have good color retention effect, and the color and luster of the specimens are basically unchanged after the specimens are placed for five years, so that the color fading phenomenon is avoided.
Test example 2
Taking the inflorescence (dark brown) of Typha angustifolia as an example, the Typha angustifolia in the same area of the map is collected at the same time, and Typha angustifolia with the size, shape and color close to the inflorescence is selected and the specimens are prepared by the methods of examples 1-5 and comparative examples 1-2 respectively. The obtained specimen was suspended in a constant temperature and humidity chamber (temperature 30 ℃ C., relative humidity 93%), and the generation of mold spots on the specimen surface was observed every day, and the results of examination are shown in Table 2.

As can be seen from table 2, in comparative example 1, paraffin is directly coated on the surface of the inflorescence, although no shedding occurs in a high-humidity environment, the mildew-proof effect of only one layer of paraffin is limited, and rare hyphae can be seen by naked eyes after three months; in comparative example 2, paraffin penetrated into the inside of the inflorescence, the mildew-proof effect was superior to that of comparative example 1, but the pretreatment step before paraffin coating was omitted, the mildew-proof effect was limited, and visible rare hyphae also inevitably appeared after twelve months. The specimens prepared in examples 1 to 5 have a good mildew-proof effect, and do not mildew under high humidity conditions.
Although the present invention has been described with reference to the specific embodiments, it is not intended to limit the scope of the present invention, and various modifications and variations can be made by those skilled in the art without inventive changes based on the technical solution of the present invention.
