A drilling type deep soil respiration measuring device and its measuring method

Abstract

The invention discloses a drilling type deep soil respiration measuring device. The drilling type deep soil respiration measuring device comprises a measuring frame, a drilling assembly and a measuring assembly; the drilling assembly comprises a drilling pipe, a mounting plate and a drilling motor; the mounting plate is connected with the measuring frame, drilling teeth are arranged at the bottomof the mounting plate, a limiting ring sleeves the drilling pipe, the drilling pipe is clamped with the mounting plate through the limiting ring, the drilling motor is arranged on the mounting plate,and the drilling motor provides power for the drilling pipe; the measuring assembly comprises a CO2 detector, a detecting pipe and a floating soil grabbing assembly. The detection pipe is sleeved withthe drilling pipe, the detection pipe is in threaded connection with the upper end of the drilling pipe, the CO2 detector is arranged on the mounting plate, a detection probe of the CO2 detector is located at the lower position in the detection pipe, and the floating soil grabbing assembly is movably arranged on the detection pipe and used for grabbing floating soil on the ground surface to be measured. The measuring device is reasonable in structural design, convenient to operate, high in soil respiration measurement accuracy and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of soil respiration detection equipment, in particular to a drilling type deep soil respiration measurement device and a measurement method thereof. Background technique [0002] Soil respiration refers to the process by which soil releases carbon dioxide, and strictly speaking refers to the production of CO in undisturbed soil. 2 All the metabolic effects of the soil, including three biological processes and one non-biological process, that is, the chemical oxidation of carbon-containing minerals, people regard the determination of soil respiration intensity as a measure of the total activity of soil microorganisms, or as an indicator for evaluating soil Therefore, research on the storage capacity of soil carbon pool and its dynamic changes will help to discuss issues such as reducing anthropogenic carbon emissions, increasing soil carbon storage, and prolonging the fixation time of soil carbon. A small ch...

Problems solved by technology

[0003] Existing soil respiration measurement devices generally have complex structures and are not easy to operate. Moreover, when the existing drilling-type soil respiration measurement devices drill the soil layer, they can easily interfere with the natural discharge of the original soil layer, causing the measurement results to be out of order. error; on the other hand, after the existing drilling soil respiration measurement device is used up, the soil at the detection point cannot be restored, resulting in the destruction of the original soil environment
