Abstract

The invention discloses a soil carbon flux measuring device. The device comprises an air storage cylinder (7), a base (2), a rack (4), a movable air storage cylinder cover (12), a cylinder cover lifting device (13), a cylinder cover translation device (15), a sensor, a display and a system control microcomputer, an air storage cylinder is formed by combining an upper fixed cylinder body (16), a lower movable cylinder body (17) and a thin elastic sleeve (24) sleeving the two cylinder bodies, the lower movable cylinder body is defined by a plurality of arc-shaped surface sliding pieces which arelongitudinally and circumferentially arranged, and each arc-shaped surface sliding piece can be adjusted in an up-down telescopic mode along with unevenness of a sample plot. The device is speciallyused for measuring the carbon flux of the soil, and has the advantages of strong adaptability to the surface condition of the ample plot to be measured, high sealing performance, strong representativeness of collected and extracted sample gas, conformity to design requirements, low error and the like. Power transmission of translation or vertical lifting of the device is carried out under the two-dimensional condition, positioning is accurate, the joint closing performance is good, and faults and damage are not likely to happen.

Description

technical field [0001] The invention relates to a soil carbon flux measuring device, in particular to a soil carbon flux measurement device in a certain area and its plant roots, microorganisms, earthworms and other animals breathing CO 2 Reflected in the carbon flux measurement setup. Background technique [0002] Carbon flux is one of the most basic concepts in carbon cycle research, which represents the total amount of carbon in an ecosystem passing through a certain ecological section. Soil carbon flux can well reflect soil respiration and its related parameters, and plays an important role in the study of carbon cycle in terrestrial ecosystems. Therefore, it is necessary to measure soil carbon flux for a long time, continuously and accurately. In an environment requiring airtightness, create airtight conditions as much as possible to reduce measurement errors, thus placing high demands on the measuring device. Some existing related soil carbon flux measurement devices...
