[0001] This utility model relates to the technical field of soil experimental equipment, and in particular to a soil salinity simulation device under different meteorological conditions. Background Technology

[0002] Soil salinity is a crucial factor affecting soil quality and agricultural production. Excessive soil salinity can lead to soil structure deterioration, stunted plant growth, and even desertification. The dynamic changes in soil salinity are influenced by various factors, with meteorological conditions (such as temperature, humidity, sunlight, and precipitation) being a major driving force. Therefore, studying the patterns of soil salinity changes under different meteorological conditions is of great significance for saline-alkali land improvement, agricultural irrigation optimization, and ecological environmental protection.

[0003] In existing technologies, traditional laboratory simulation devices have relatively limited functions, typically only able to simulate single meteorological conditions (such as temperature or humidity), and cannot comprehensively reflect the changes in soil salinity under the combined effects of multiple meteorological conditions. Furthermore, existing devices have low integration in real-time soil salinity monitoring, data acquisition, and analysis, making it difficult to achieve efficient and accurate experimental research.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] A soil salinity simulation device under different meteorological conditions, such as Figure 1-4 As shown, the system includes: an environmental controller 1, a soil sample container 2, a water storage tank 3, and a connector 4. The environmental controller 1 includes a gate controller 11, a display screen 12, a temperature control module 121, a water control module 122, and a data monitoring and processing module 123. The display screen 12 is electrically connected to the temperature control module 121, the water control module 122, and the data monitoring and processing module 123. The display screen 12 is used to display real-time data on temperature, precipitation, and salinity monitoring. The temperature control module 121 is used to control the internal temperature of the device. The water control module 122 is used to simulate different amounts and frequencies of precipitation and adjust the internal humidity of the device. The data monitoring and processing module 123 is used to collect and process data from the environmental control unit and the salinity monitoring unit. The gate controller 11 is electrically connected to the air vent 221 of the disassembly sieve 22, and the gate controller 11 can control the gate plate 222 of the disassembly sieve 22 to close. The soil sample container 2, including the supporting plate 21, the disassembly sieve 22, the sampling port 23, and the handle 24, are all made of metal. The disassembled sieve 22 has a sampling port 23 on its side and a vent 221 that can be closed. The water tank 3 is made of glass and is connected to the conduit 31, which controls the on / off state of the nozzle 32. The conduit 31 is made of rubber, and the nozzle 32 is made of glass. The connector 4 includes a connecting post 41, a lampshade 42, and a bulb 43. The connecting post 41 and lampshade 42 are made of metal, and the bulb 43 is made of glass. The bulb 43 can simulate different light intensities and light cycles to adjust the internal temperature of the device.

[0021] In the use of this invention, researchers can fill soil sample container 2 with clay (or loam or other soils with different physical and chemical properties) to ensure that each layer of soil is evenly distributed. The disassembly screen 22 is installed at depths of 0.3m, 0.6m and 1m in the soil sample container 2. In the initial state, the pores 221 are closed to prevent water penetration. Water with different salt concentrations, nutrients, pH values ​​and heavy metal contents is prepared in the water storage tank 3 to simulate scenarios such as seawater intrusion, fertilization, acid rain and heavy metal pollution. Different temperature and precipitation conditions are set by the environmental controller 1. The brightness and temperature of the bulb 43 are adjusted by the temperature control module 121 to simulate high temperature, low temperature or day and night temperature difference. The water spray volume and frequency of the nozzle 32 are adjusted by the water control module 122 to simulate drought, normal precipitation or rainstorm conditions. After completing the preliminary preparations, the water tank 3 is opened, and the prepared water is evenly sprayed onto the soil sample surface through the nozzle 32. Depending on the experimental requirements, the air vents 221 of the disassembly sieve 22 are selectively opened to allow water to penetrate to different soil depths. Soil samples are periodically collected through sampling ports 23 at different depths to determine their salinity, pH value, nutrient elements, and heavy metal content. The data monitoring and processing module 123 compares the salinity changes of different soil types under different meteorological conditions, analyzing the impact of various scenarios such as seawater intrusion, fertilization, acid rain, and heavy metal pollution on soil salinity, and studying the salinity distribution patterns at different soil depths. This experimental setup can effectively simulate various meteorological conditions and pollution scenarios, providing a reliable experimental platform for studying soil salinity changes. By comparing salinity changes at different soil types and depths, a scientific basis can be provided for agricultural production, environmental protection, and soil remediation.
