Embodiment 1

[0050] The teaching plant resin specimen of the embodiment of the present invention, preparation method is as follows:

[0051] Step 1, collect the green plants that need to be made into resin specimens as plant specimens, and perform conventional pretreatment on the collected plant specimens; the conventional pretreatment is to remove soil, decayed leaves and other dirt from the collected green plants, and trim to remove excess branches and leaves.

[0052] Step 2, preparation of dry powder: grind anhydrous silica gel into anhydrous silica gel powder that can pass through a 50-100 mesh screen, and then mix it with alumina powder at a mass ratio of 1:1.5 to obtain a mixed dry powder.

[0053] Step 3, placing the plant specimens in a drying box, using the obtained mixed dry powder to completely embed the plant specimens, and then drying them;

[0054] Embedding plant specimens with mixed dry powder is carried out as follows: spread 2 cm of mixed dry powder on the bottom of the...

Embodiment 2

[0065] The teaching plant resin specimen of the embodiment of the present invention, preparation method is as follows:

[0066] Step 1, collect the green plants that need to be made into resin specimens as plant specimens, and perform conventional pretreatment on the collected plant specimens; the conventional pretreatment is to remove soil, decayed leaves and other dirt from the collected green plants, and trim to remove excess branches and leaves.

[0067] Step 2, preparation of dry powder: grind anhydrous silica gel into anhydrous silica gel powder that can pass through a 50-100 mesh screen, and then mix it with alumina powder at a mass ratio of 1:3 to obtain a mixed dry powder.

[0068] Step 3, placing the plant specimens in a drying box, using the obtained mixed dry powder to completely embed the plant specimens, and then drying them;

[0069] The embedding of plant specimens with mixed dry powder is carried out as follows: spread 5cm of mixed dry powder on the bottom of...

Embodiment 3

[0080] The teaching plant resin specimen of the embodiment of the present invention, preparation method is as follows:

[0081] Step 1, collect the green plants that need to be made into resin specimens as plant specimens, and perform conventional pretreatment on the collected plant specimens; the conventional pretreatment is to remove soil, decayed leaves and other dirt from the collected green plants, and trim to remove excess branches and leaves.

[0082] Step 2, preparation of dry powder: grind anhydrous silica gel into anhydrous silica gel powder that can pass through a 50-100 mesh screen, and then mix it with alumina powder at a mass ratio of 1:2 to obtain a mixed dry powder.

[0083] Step 3, placing the plant specimens in a drying box, using the obtained mixed dry powder to completely embed the plant specimens, and then drying them;

[0084] The embedding of plant specimens with mixed dry powder is carried out as follows: spread 3 cm of mixed dry powder on the bottom o...

Abstract

The invention relates to a manufacturing method of a plant resin specimen for teaching. The method comprises the following steps that (1) plant specimens are collected and are subjected to conventional pretreatment; (2) anhydrous silica gel is ground into powder; the powdery anhydrous silica gel and aluminum oxide powder are uniformly mixed according to a certain proportion to obtain mixed drying powder; (3) the plant specimens are put into a drying box, are completely embedded by the obtained mixed drying powder, and are then subjected to drying treatment; (4) the dried and treated plant specimens are taken out from the drying box, the redundant mixed drying power on the surface is cleared away, and then, a 30W ultraviolet lamp is irradiated for 3 to 5 minutes for sterilization inactivation treatment; (5) the treated plant specimens are put into a mold to be subjected to epoxy resin glue embedding; (6) after the epoxy resin glue is solidified, the plant resin specimen is obtained. The specimen manufactured by the method has the characteristics of transparency, sealing, oxidation resistance, long-time color retention, lightweight, portability, no toxicity, no harm and the like; the problem that the existing resin specimen cannot perfectly protect the plant pigment can be solved.

Description

technical field [0001] The invention relates to the technical field of plant specimens, in particular to a method for making plant resin specimens for teaching. Background technique [0002] At present, the plant specimens used for teaching in scientific research institutions mainly include wax leaf specimens and soaked specimens. The production of wax leaf specimens is mainly made through the steps of shaping-pressing and drying-binding-preservation, etc., but due to the non-sealed binding, the specimens are easy to regain moisture and cause moldy damage to the specimens, and exposure to the air can easily cause the leaves to be oxidized and turn yellow. Therefore, wax leaf specimens cannot be preserved for a long time, and major scientific research institutes must replace them regularly, otherwise the use effect will be affected. As we all know, some precious specimens have a small stock, or are rare and endangered species, or have been extinct. The possibility is extreme...
