Abstract

The invention relates to the technical field of soil respiration measurement, in particular to an indoor soil culture and soil respiration measuring system. The indoor soil culture and soil respiration measuring system comprises an air inlet system, a first control valve, a CO2 filtering device, a soil culture system, a second control valve, a measurement analyzer and a main control computer, wherein the air inlet system is connected with the soil culture system through the first control valve, the CO2 filtering device is connected with the first control valve, the soil culture system is connected with the measurement analyzer through the second control valve, and the main control computer is in signal connection with the first control valve, the second control valve and the measurement analyzer. By means of the indoor soil culture and soil respiration measuring system, it can be achieved that CO2 released when indoor soil microorganisms respire is continuously automatically measured in real time, and research and development requirements of current indoor soil culture measurement are met.

Description

technical field [0001] The invention relates to the technical field of soil respiration measurement, in particular to an indoor soil cultivation and soil respiration measurement system. Background technique [0002] At present, in scientific research experiments such as ecology, grass science, earth science and soil science, soil sampling and analysis are carried out, especially the analysis of microorganisms in the soil, and the changes of microorganisms in the soil are determined. Determination of soil microbial respiration is an important indicator for the determination of microbial changes in soil, and plays an important role in the study of the decomposition and turnover of organic matter in soil, and the carbon cycle between soil and the atmosphere. Indoor soil culture can accurately control external conditions such as humidity, temperature and light according to research needs, as well as internal soil conditions such as soil moisture and nutrients, to cultivate soil ...
