Abstract

The invention discloses a method for collecting and manufacturing a suspension type thin-layer soil monolith, and relates to a method for collecting and manufacturing a soil monolith. The problem that the monolith hardly moves, lacks of continuity and integrity and has a severely damaged shape in the process of manufacturing the soil monolith is solved. The method comprises the following steps of: manufacturing a soil sampler, a movable sealing cap and a monolith supporting box; excavating a soil profile pit; cultivating a soil pillar with the same inner diameter as the soil sampler on the soil profile, and sleeving the soil pillar by using a soil sampler frame; flatly supporting the soil sampler and the soil pillar to the ground; invertedly fastening the smoothened soil pillar in the monolith supporting box coated with polyvinyl alcohol sol, and selecting different volume ratios of polyvinyl acetate emulsion to water according to different soil textures; spraying an adhesive on the soil pillar so as to make the adhesive naturally infiltrate saturation, and conveying the monolith after the adhesive is dry and the monolith is solidified; and exhibiting the monolith in a show window, and giving character and picture caption to the monolith. The method is suitable for collecting and manufacturing the thin-layer soil monolith.

Description

technical field [0001] The invention relates to a method for collecting and manufacturing a whole section of soil sample, in particular to a method for collecting and making a whole section of a suspended thin layer of soil sample, and belongs to the technical field of soil research. Background technique [0002] The whole soil sample is a soil product made by selecting a relatively representative soil profile, collecting objective, true, continuous and complete soil samples according to the soil occurrence level, and processing them. [0003] The whole soil sample is an indispensable auxiliary tool for the teaching and scientific research of physical geography and soil science. By reading and studying soil profiles, geographers and soil scientists can understand the biological cycle characteristics and geochemical migration characteristics of elements in the soil from its morphological characteristics and physical and chemical properties, and obtain environmental informatio...
