A soil-vegetation environment monitoring simulation device

Abstract

The present invention relates to the technical field of ecological monitoring simulation, in particular to a soil-vegetation environment monitoring simulation device, which includes a controller. device, the potting cylinder includes a cylindrical frame and a telescopic cylinder, the bottom of the cylindrical frame is provided with a mesh plate, the positioning frame includes a vertical frame and several positioning mechanisms, and the drainage device includes a ring Pipe fittings, the bottom end of the cylindrical frame is provided with several sampling holes, and the annular pipe is connected to the sampling holes through several diversion pipes. The invention dynamically monitors soil temperature, humidity and electrical conductivity, and injects isotope tracers into different soil layers of potted drums. , can detect the trend of ions in the soil; collect soil solutions in different soil layers for solute migration process, can simulate groundwater, simulate different soil layer thicknesses, and restore the degree of compaction of different soil layers in the soil to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of ecological monitoring simulation, in particular to a soil-vegetation environment monitoring simulation device. Background technique [0002] The increase in global temperature in recent years has brought new challenges and opportunities to scientific research. [0003] The growth of wheat requires a suitable temperature. As the global climate warms, the yield of wheat will be greatly affected. How to study the growth of wheat roots under soil warming and high-temperature ring culture has always been a technical problem in this field. The existing warming devices only increase the air temperature but cannot study the influence of warming on wheat roots. The growth situation of the wheat will also greatly affect the growth situation of the wheat, so the experimental data obtained are not accurate enough. [0004] The disclosed application number is 201821217863.4, which is used to analyze the influence of...

AI Technical Summary

Problems solved by technology

[0006] (1) The structure of the drawers in this scheme is the same and cannot be adjusted. For important parts, the sampling area needs to be refined, and the width of the drawer cannot be adjusted, which brings unnecessary trouble to the experiment. The drawer is prone to displacement and needs to be adjusted in real time

[0007] (2) The soil tamping degree of this scheme cannot be adjusted, and the soil in the drawer box cannot be made to be as close as possible to the tamping degree of each soil layer of the ground soil, which affects the authenticity of the experimental results

[0008] (3) staff sampling, the existing method is to manually insert a bobbin into the soil, the sampling strength is relatively large, and it is relatively troublesome, and the height of the potted drum is relatively high. The samples that need to be sampled are relatively difficult, which increases the safety hazard when working in the air

[0009] (4) The simulation of groundwater flow is not involved, the accuracy of the experimental results is low, and it is impossible to simulate the real environment of vegetation growth

[0010] (5) There are no factors involved in simulating the influence of precipitation changes (rainfall increase and decrease) outdoors;
