Problems solved by technology
[0004] In the past studies, the growth environment of plants was mainly simulated with flowerpots of various materials, which can simulate karst habitats in terms of soil volume and thickness, but they cannot be very good for the unique chemical and physical characteristics of karst niches. simulation, therefore, the present invention proposes a kind of experimental device for simulating karst niche

Embodiment Construction
[0015] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0016] Embodiments of the present invention: the structural representation of the experimental device for simulating the karst soil niche is as follows Figure 1~3 As shown, it includes a carbonate rock floor 1, a carbonate rock wall 2 and a carbonate rock partition 3, and the carbonate rock wall 2 is fixed on the carbonate rock floor 1 and forms a Rectangular trough, in the rectangular trough surrounded by carbonate rock slabs 2, a carbonate rock partition 3 is fixedly installed, and the carbonate rock partition 3 divides the inner space of the rectangular trough into a four-grid soil holding tank or Jiugong grid soil holding tank. Carbonate rock heightening plates 4 are fixedly installed on the tops of the carbonate rock wall 2 and the carbonat...

The invention discloses an experimental device for simulating the ecological niche of karst soil. The device comprises a carbonate rock floor, carbonate rock coamings and carbonate rock clapboards, the carbonate rock coamings are fixed on the carbonate rock floor to form a rectangular trough, the carbonate rock clapboards are fixed in a rectangular trough formed by the carbonate rock coamings, andthe carbonate rock clapboards divide the internal space of the rectangular trough into a four-box soil accommodating trough or a nine-box soil accommodating trough. All above materials are made of carbonate rocks, so the simulated ecologic niche is consistent with actual karst ecologic niche in chemical properties and physical properties, so the authenticity and reliability of the experiment areimproved; and the soil accommodating trough having different sizes can be formed through combining carbonate rock plates having different sizes, and carbonate rock elevation plates also can be arranged on the soil accommodating trough, so the karst ecologic niche of soil having different thicknesses can be simulated.
Description
technical field [0001] The invention relates to an experimental device for simulating a karst soil niche, belonging to the technical field of niche experimental devices. Background technique [0002] The formation process of karst landforms is mainly the dissolution of carbonate rocks. Affected by the tendency of rock formations and differential dissolution of rocks, the bedrock in relatively high places is exposed, and the low-lying parts contain soil, which makes the soil distribution uneven and discontinuous. A variety of soils contain microenvironments and become niche habitats for plant growth. There are several types of niches, such as stone surface, soil surface, stone ditch (including stone crevices and troughs), and stone pits. The main difference lies in the total amount and thickness of the soil. The process of forming soil by carbonate rock dissolution is slow, so the total amount of regional soil and soil thickness are relatively low compared with the normal la...
