Soil-vegetation environment monitoring simulation device

Abstract

The invention relates to the technical field of ecological monitoring simulation, in particular to a soil-vegetation environment monitoring simulation device. The device comprises a controller, the simulation device comprises a plurality of potting barrels stacked from top to bottom, a positioning framework and a plurality of drainage devices, and each potting barrel comprises a cylinder frame and a telescopic cylinder; a mesh plate is arranged at the bottom of the cylindrical frame, the positioning skeleton comprises a vertical frame and a plurality of positioning mechanisms, the drainage device comprises an annular pipe fitting, a plurality of sampling holes are formed in the bottom end of the cylindrical frame, and the annular pipe fitting is communicated with the sampling holes through a plurality of flow guide pipes. According to the invention, soil temperature, humidity and conductivity are dynamically monitored; wherein isotopic tracers are injected into different soil layers of the potting barrel, so that the trend of ions in the soil can be detected; and then the soil solutions of different soil layers are collected for a solute transport process, underground water and different soil layer thicknesses can be simulated, and the compaction degrees of different soil layers in the soil are reduced to the maximum 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 heating and high-temperature ring culture has always been a difficult problem in this field. In the process of scientific research, how to deal with it? The existing heating devices only increase the air temperature and cannot be well studied. The influence of temperature increase on the root system of wheat and the growth of the root system will also greatly affect the growth of wheat, so the experimental data obtained are not accurate enough.

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;
