Problems solved by technology

However, at present, researchers mainly use single-channel or manual methods to complete relevant testing work, and the multi-channel, automatic switching rapid and continuous measurement device for soil microbial respiration has not been developed and developed, so that the analysis and testing work cannot be carried out in large quantities. Fundamentally address the limiting factors of soil microbial respiration (soil carbon mineralization) testing efforts

Abstract

The invention relates to the field of machinery, and in particular provides a device for automatically continuously testing soil microbial respiration. The device comprises a constant temperature culture system, a CO2 initial concentration control and gas sampling system and a CO2 concentration analyzer. The device can adjust CO2 concentration and gas flow and flow velocity in the device at the beginning of a test according to requirements, and has a function of automatically switching different test specimens. By the device, the indoor soil microbial respiration can be quickly and continuously tested on line successfully, and the device can be widely applied to the related fields of soil carbon turnover, microorganisms and the like.

Description

Technical field: [0001] The invention relates to the field of agricultural machinery, and specifically provides an automatic and continuous measurement device for indoor soil microbial respiration. Background technique: [0002] Soil carbon storage and carbon cycle are currently research hotspots in the fields of ecology, soil science, and environmental science at home and abroad; the study of soil microbial respiration (also known as carbon mineralization in culture experiments) is of great help in revealing the decomposition and turnover of soil organic matter, soil carbon sources, etc. The sink function and so on play an important role. In recent years, the research on global change has been popular, and the research work in soil respiration and related fields has been widely valued by scientific researchers from all over the world. [0003] Soil indoor incubation experiment (Incubation experiment) can precisely control various experimental factors, such as temperature, ...
