Abstract

The invention relates to an overground and underground synchronous carbon flux measuring experimental device comprising a monitoring device for studying the soil carbon flux and a transparent cylindrical body for cultivating plants. A partition plate is arranged at the middle part of the transparent cylindrical body and is used for separating a ground portion and a soil portion of the plant in twoseparate chambers. A liquid supply interface for providing a nutrient solution for the plant is further disposed on the side wall of the chamber for accommodating the soil portion of the plant. Through holes through which plants pass are formed in the partition plate. The two ends of the transparent cylindrical body are connected to monitoring holes of the monitoring device respectively. According to the invention, the overground and underground synchronous carbon flux measuring experimental device is used for monitoring parameters related to soil respiration below the surface as well as thecarbon flux variation parameters above the ground to obtain two groups of overground and underground monitoring data, thereby analyzing the soil respiration relationship. The overground and underground synchronous carbon flux measuring experimental device has the great significance in prompting the study on the carbon flux in the terrestrial ecosystem.

Description

technical field [0001] The invention relates to the technical field of soil carbon flux measurement, in particular to an experimental device for synchronous measurement of aboveground and underground carbon flux. Background technique [0002] Soil respiration is the main way for carbon to return to the atmosphere from terrestrial ecosystems, and it is also a characterization of life activities in soil. Accurate determination of its release is the key to evaluating biological processes in ecosystems. By monitoring soil respiration and its related parameters, the responses of roots and soil microbes to climate change can be estimated. Soil CO 2 Fluxes are affected by a variety of complex physical and biological processes in time and space. Long-term, continuous, and accurate measurement of soil carbon fluxes is of great significance to the study of carbon fluxes in terrestrial ecosystems. [0003] At present, relevant researchers in this field have achieved some results in t...
