The portable device used for collecting cornfield greenhouse gas is simple in structure, is convenient to use, avoids influences on plant growth caused by an overlarge air-taking device, guarantees normal growth of plants, rapidly and accurately monitors the greenhouse gas emissions of cornfield soil, and meanwhile lowers experimental cost.
Description
Technical field
The utility model relates to a kind of mancarried device, especially relates to a kind of for the mancarried device of collecting the wheatland greenhouse gases.
Background technology
In recent years, scientific circles build consensus, the increase of the atmosphere percent of greenhouse gases concentration that human activity causes is the main cause that causes climate change, the farmland is as the part of terrestrial ecosystems, be important greenhouse gas emission source, so the monitoring of soil greenhouse gas emissions also become one of people's attention focus.What present existing farmland greenhouse gas emission was adopted is the static chamber experimental provision, and most volumes are bigger, and plant is grown in the collector, and along with the growth of crop, the volume of static chamber can not satisfy the normal growth of crop, needs to change static chamber; When more exchanging the static chamber of gas for, except the cost of changing static chamber was higher, the replacing process caused the disturbance of soil easily, causes the destruction of soil prototype structure, had influenced the original experimentation environment of soil greenhouse gases samplings, also can influence the growth of crop; The greenhouse gas emission of the wheatland ecosystem mainly comes from soil, and wheat plant itself is less to the influence of greenhouse gas emission; Therefore, along with the continuous growth of crop, existing collector has not been suitable for the collection of wheatland percent of greenhouse gases.
The utility model content
The utility model proposes a kind of simple in structure, easy to use, and avoided because the excessive influence to plant strain growth of collector, guaranteed the normal growth of crop, monitor wheatland soil greenhouse gas emissions quickly and accurately, reduced the mancarried device that is used for collecting the wheatland greenhouse gases of experimentation cost simultaneously.
In order to realize this purpose, the utility model is taked following scheme:
A kind of for the mancarried device of collecting the wheatland greenhouse gases, comprise annular base and static chamber, described annular base cooperates with static chamber, the top of annular base is provided with the water seal groove, the bottom of static chamber is opening, the top of static chamber is provided with first perforate and second perforate, is provided with the high elasticity silica rubber plug in first perforate.
As preferably, the xsect of described static chamber is round-shaped.
As preferably, the top of described static chamber is provided with handle.
As preferably, described handle arrangements is between first perforate and second perforate.
As preferably, described handle is arcuate shape.
As preferably, the xsect of described first perforate is round-shaped.
As preferably, the xsect of described second perforate is round-shaped.
As preferably, described first perforate is identical with the second hole shape size.
The beneficial effects of the utility model: because described annular base cooperates with static chamber, the top of annular base is provided with the water seal groove, the bottom of static chamber is opening, the top of static chamber is provided with first perforate and second perforate, be provided with the high elasticity silica rubber plug in first perforate, so being used for installing for syringe, first perforate gathers the high elasticity silica rubber plug that gaseous sample is used, insert the syringe that has T-valve when being used for getting gas, when getting gas, insert syringe and spur syringe repeatedly so that the gas mixing in the static chamber begins to get gas, syringe is moved to the scale place that will get, close threeway, extract syringe and gas is injected the pipe that vacuumizes in advance; After each sampling finishes, open static chamber; Second perforate is used for installing the thermometer of measuring temperature, to be used for measuring the inside and outside temperature of static chamber; The result of study that the monitoring of adopting this device to carry out the farmland greenhouse gas emission obtains, consistent with the result of study of conventional static chamber gas collector, avoided simultaneously because the excessive influence to plant strain growth of collector, guaranteed the normal growth of crop, monitor wheatland soil greenhouse gas emissions quickly and accurately, reduced experimentation cost simultaneously.
