Description

Technical Field

[0001] This utility model relates to the field of soil technology, and more specifically to a field measurement device for soil carbon sequestration and emission reduction. Background Technology

[0002] As the global climate change problem becomes increasingly severe, soil carbon sequestration and emission reduction are of great significance for mitigating the greenhouse effect. Accurately measuring the amount of carbon sequestration and emission reduction in field soils is crucial for assessing soil ecosystem functions and formulating agricultural strategies to cope with climate change.

[0003] Currently, the main methods for measuring soil carbon sequestration and emission reduction include laboratory analysis and in-situ field measurement. However, existing soil carbon sequestration and emission reduction measurement devices have many shortcomings.

[0004] Laboratory analysis: This usually requires collecting soil samples and sending them to the laboratory for chemical analysis. Although it has high precision, it has the following drawbacks: high time cost, as the cycle from sampling to obtaining analysis results is long and data cannot be obtained in real time; destructive sampling, as the sampling process can damage the soil structure and affect subsequent continuous monitoring; and transportation and preservation issues, as soil samples may undergo physical or chemical changes during transportation and preservation, affecting the accuracy of the test results.

[0005] In-situ field measurement: Although some existing field measurement equipment can achieve in-situ monitoring, the following problems still exist: low degree of automation, the sampling and analysis process relies on manual operation, which is inefficient and prone to human error; poor portability, existing equipment is bulky and difficult to use flexibly in complex field environments; single function, most equipment can only measure a single indicator (such as soil organic carbon or gas emissions), which cannot comprehensively reflect the soil's carbon sequestration capacity; power supply problem, field operation environments usually lack a stable power supply, and the equipment's endurance is insufficient.

[0006] Therefore, how to provide a simple-to-operate, comprehensive, and rapid field measurement device for soil carbon sequestration and emission reduction that can measure multiple related factors is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
