Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing carbon dioxide collection device measures the soil respiration intensity on a relatively flat ridge, ignoring the difference between the ridge and the ridge to the soil respiration, and the dead angle at the ridge leads to large measurement errors and low precision. Problems, proposed A carbon dioxide harvesting device for measuring soil respiration rate in ridge farming

specific Embodiment approach 1

[0008] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, the collection device of this embodiment is made of outer cover 1, fan 2, support 3, collection bottle 4 and screw plug 5, and described support 3 is arranged in the ditch 7 of measured soil, and described collection bottle 4 is arranged On the platform of the support 3, the outer cover 1 is surrounded by four side walls and an upper cover, the support 3 and the collection bottle 4 are arranged in the outer cover 1, and the outer cover 1 is arranged on two adjacent sides of the measured soil. On a ridge platform 6, and the lower part of the outer cover 1 is inserted into the soil to be measured, the side wall in the outer cover 1 is provided with a fan 2 for fully mixing the gas, and the screw plug 5 is plugged in the collecting bottle 4. Inside the bottle mouth, the collection bottle 4 is filled with 1.0-1.5mol / L NaOH solution.

specific Embodiment approach 2

[0009] Specific implementation mode two: combination figure 1 The present embodiment will be described. The housing 1 of the present embodiment is made of tinplate. The advantage of this structure is that the tinplate is a dark metal, which can better eliminate the influence of light and the test effect is good. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0010] Specific implementation mode three: combination figure 2 To describe this embodiment, the shape of the lower opening of the housing 1 of this embodiment is a square, and the length of each side of the square is equal to the distance between the ridges of the soil to be measured. The advantage of this structure is to avoid dead angles in furrows and ensure accurate measurement results. Other components and connections are the same as those in the first embodiment.

Abstract

The invention provides a carbon dioxide collecting device for measuring the respiratory rate of ridge culture soil, which relates to a carbon dioxide collecting device for measuring the respiratory rate of soil. The invention aims to solve the problems that by measuring the soil respiration intensity on a relatively flat ridge platform, the current detection device neglects the difference to soil respiration between a ridge ditch and the ridge platform, and the ridge ditch has dead corners, thereby causing large measurement error and low accuracy. A bracket is arranged in the ridge ditch of the soil to be measured; a collection bottle is arranged on the platform of the bracket; four side walls and an upper cover are integrated into an outer housing; the bracket and the collection bottle are arranged in the outer housing; the outer housing is arranged on two ridge platforms of the soil to be measured; the lower part of the outer housing is inserted into the soil to be measured; and a fan for fully mixing gases is arranged on the side wall in the outer housing. The carbon dioxide collecting device of the invention is used for collecting carbon dioxide released by soil respiration.

Description

technical field [0001] The invention relates to a carbon dioxide collection device for measuring soil respiration rate. Background technique [0002] At present, with the advancement of science and technology and the increase of greenhouse gases in the atmosphere, people's research methods and means of soil respiration have been deepened, and the impact of soil respiration on the greenhouse effect has become more clear. Greenhouse gas scientists at home and abroad attach great importance to the study of soil respiration. As a necessary process of soil carbon pool turnover, soil respiration is the emission of CO from soil to the atmosphere. 2 Therefore, it has become a hotspot and a breakthrough in greenhouse gas research. [0003] The traditional carbon dioxide collection device generally uses a circular cover to absorb carbon dioxide on a relatively flat ridge and measure the soil respiration intensity, ignoring the ridge and mistakenly assuming that the soil respiration ...
