Abstract

The invention provides an automatic microbial respiration rate measuring device, and relates to the field of instruments for scientific research on agriculture and the ecological environment, aiming at solving the problem that in the prior art, the microbial respiration rate can not be automatically and continuously measured on a large scale. The automatic microbial respiration rate measuring device comprises at least one culture flask, a multi-channel control system, a carbon dioxide analyzer and a data acquisition unit, wherein the multi-channel control system comprises at least one channel,and the channels are respectively connected with the culture flasks in a corresponding way; the channels are used for obtaining gas to be tested in the culture flasks; the carbon dioxide analyzer isconnected with the multi-channel control system and is used for measuring the concentration data of carbon dioxide in the gas to be tested; the data acquisition unit is connected with the carbon dioxide analyzer, and is used for acquiring the concentration data of the carbon dioxide and determining the microbial respiration rate according to the concentration data of the carbon dioxide.

Description

technical field [0001] The invention relates to the field of instruments for scientific research on agriculture and ecological environment, in particular to an automatic measuring device for microbial respiration rate. Background technique [0002] Soil microbial respiration rate data is an important indicator reflecting the decomposition process of soil organic carbon and microbial activity, and plays an important role in the study of ecosystem ecology and the process of global carbon cycle. In traditional research, the measurement methods for obtaining soil microbial respiration rate data are all based on manual measurement methods such as lye absorption method, infrared analyzer method, or gas chromatography, which require a lot of manpower and material resources when the sample volume is large. An automatic determination device based on multiple sample automatic switching technology will be able to solve these problems well. Although relevant equipment is available at p...
