Description
Technical field
The utility model is related to ecology and soil field, specifically a kind of portable soil gas flux sampling cartridges
It sets.
Background technology
In the 1940s, carbon dioxide (the CO that land source carbon storehouse is discharged to air2) total amount has been more than geology source fossil
The input quantity of fuel combustion.Terrestrial ecosystems become CO2, methane (CH4) and nitrous oxide (N2O) greenhouse gases is important
Emission source.Field carries out soil gas acquisition and analysis to the different type ecosystem on the spot has research greenhouse gas emission
Important scientific meaning.The device for acquiring soil gas domestic at present is more, but focuses mostly in large-scale, heavy, fixed
It is long-term field fixed point observation, not portable, at high price, and it is less suitable for the light portable device of different soil modes,
Especially field forest ecosystem, with a varied topography, understory species are rich and varied, heterogeneous strong, frequently by different vegetation
The progress acquisition of gas of multipoint random, test analysis under type, it is therefore desirable to it is a kind of be convenient for carrying, the gas of strong applicability is adopted
Sampling device.Large-scale fixed sampling apparatus mainly has firm banking, babinet, upper cover, battery, ground temperature sensor etc., into promoting the circulation of qi
The acquisition of body, used in research.
Problem of the existing technology：
(1) more demanding to wild environment, soil wants smooth with firm banking first, and the followed by soil texture is uniform, different
Matter is small, and in addition sampling site is broad, and tall and big vegetation is few on the ground, and block is weak.
(2) large-scale sampler babinet is heavier, and fixed sampled point can be just carried to by being typically necessary transporting equipment, to can not
Into vehicle sampling will also expend a large amount of human resources, increase the difficulty of sampling, hit research enthusiasm, influence entire
Experimental study.
Utility model content
In view of the deficiencies in the prior art, the utility model provides a kind of portable soil gas flux sampling apparatus, adopts
With bilateral babinet, the sampling of soil gas flux is realized.
In order to achieve the above object, the utility model uses the following technical solution：
A kind of portable soil gas flux sampling apparatus, device include：Lower box and upper box, lower box and upper box
It is connected by screw thread, upper box is connected by upper cover interface with lid sealing, and lid is equipped with handle, gas production hole and venthole,
Gas-guide tube one end is connected with gas production hole, and the other end is blocked using rubber stopper, and syringe can fill in air guide trimmer valve across rubber
Gas production.
Preferably, sharp below lower box, soil can be easily inserted.
Preferably, lower box is equipped with scale, and the threaded adjusting by being connected with upper box is inserted into the depth of soil.
Preferably, it is opened when venthole close the cover, to alleviate air pressure in case, resistance when closing lid is reduced, to alleviate case
Interior air pressure, acquisition gas are closed after starting using rubber stopper.
Advantageous effect：The beneficial effects of the utility model are：Simple in structure, easy to operate, material is slim and graceful, and babinet is small
Ingeniously, portable, it is at low cost, it is applicable to field condition complex environment condition, it may be convenient to it is mobile, to be adopted to different
Sampling point carries out multi-point sampling, increases the stability and repeatability of experimental result.

Case illustrate only the structure and/or processing step closely related with scheme according to the present utility model in the accompanying drawings, and omit
Relationship little other details.
Embodiment 1
A kind of portable soil gas flux sampling apparatus is present embodiments provided, as shown in attached drawing 1-2, device includes：
Lower box 1 and upper box 2, lower box 1 are connected with upper box 2 by screw thread, and upper box 2 is sealed by upper cover interface 3 and lid 4
It is connected, lid 4 is equipped with handle 7, gas production hole 8 and venthole 9, and 5 one end of gas-guide tube is connected with gas production hole 8, and the other end uses rubber
Leather plug blocks, and syringe 10 can fill in 6 gas production of air guide trimmer valve across rubber.
Further, 1 lower section of lower box is sharp, can be easily inserted soil.
Further, lower box 1 is equipped with scale, and by the threaded adjusting being connected with upper box 2 and measures insertion
The depth of soil.
Further, venthole 9 is opened in close the cover, to alleviate air pressure in case, reduces resistance when lid lid, acquisition
Gas is closed after starting with rubber stopper.
Embodiment 2
A kind of portable soil gas flux method of sampling is present embodiments provided, there will be the round box of blade to insert first
Enter deep about 3-6cm in soil, the gap on covering babinet periphery is put into thermometer, about covers upper cover after ten minutes, from the rubber of long tube
The acquisition of gas is carried out at Jiao Kou with three unicom needle tubings, the number and time interval of sampling can be set according to research purpose, flexibly
It is convenient, it is simple and practical.
