Novel technology for making soil monolith for exhibition and teaching

Abstract

The invention discloses a novel technology for making a soil monolith for exhibition and teaching, which belongs to the field of soil specimen making. The technology includes the following steps: S1,determining the specification and shape of a specimen according to the soil property and the teaching or exhibition need; S2, carrying out physical finishing and drying of a whole original soil profile; S3, carrying out moth prevention and impregnation treatment; S4, selecting and sticking a specimen bearing backboard; S5, carrying out surface treatment of a rough specimen; and S6, carrying out specimen stereotyping and moisture-proof and oxidation-proof treatment. The specification and shape of the specimen made in the invention can be determined according to the needs of experimental teaching of soil courses and popularization of common knowledge of natural sciences, the specimen can directly reflect the structure and hierarchy of soil profiles, and the physical and chemical properties of soil basically remain in the original state. The specimen is portable and easy to transport and store, and is suitable for long-term use. The specimen can be displayed arbitrarily in classrooms andexhibition halls, including being placed uprightly, obliquely or horizontally.

Description

technical field [0001] The invention relates to the field of making soil samples, in particular to a new process for making whole sections of soil samples for exhibition and education. Background technique [0002] The whole soil specimen is a longitudinal section specimen from topsoil to subsoil and across the entire soil profile. After collection and production, it is often used for scientific research, teaching, museum collection, and popularization and display of natural science knowledge. Compared with other forms of soil samples, the collection and manufacture of whole soil samples is difficult, costly, and easily damaged. [0003] The original production technology was not systematic, and the soil samples were exhibited and stored for a long time, and they were prone to oxidative discoloration, cracking, falling off, dampness or insect infestation. In addition, the display form of the exhibition is dull and boring, lacks aesthetic feeling, and is not attractive enoug...

Problems solved by technology

Compared with other forms of soil samples, the collection and manufacture of whole soil samples is difficult, costly, and easily damaged

[0003] The original production technology is not systematic, and soil samples are prone to oxidative discoloration, cracking, falling off, moisture return or insect infestation after being exhibited and stored for a long time

In addition, the display form of the exhibition is dull and boring, lacks aesthetic feeling, and is not attractive enough, which is an important factor hindering the popularization of soil knowledge and science
