Abstract
The utility model provides a kind of forest soil respiration sampler, including PVC cylindrical, and the insertion section of uniform dentation is provided with into bottom PVC cylindrical.The utility model material easily obtains, is simple in structure, is easy to use, removing and installing easy and good seal performance, can ensure field continuous observation.
Description
Technical field
It the utility model is related to a kind of measuring device, more particularly to a kind of forest soil respiration sampler.
Background technology
Soil respiration refers to that soil discharges CO2Process, be mainly derived from oxidation of the Soil Microorganism to organic substance
Decomposition and root system respiration, seldom partly come to the breathing of Soil Protozoan and chemical oxidation.In recent years, as global climate becomes
It is melted into the hot fields for the public and scientific research, CO2As one of most important greenhouse gases, the standard in its source, remittance and flux
Really measure is particularly important.Soil is a carbon storehouse huge in nature, is Atmospheric CO2Important source or remittance, its flux
It is huge, CO in soil2Slight change can also cause Atmospheric CO2The significant change of concentration.So in soil respiration continuous mode
In, CO2The accurate measure of flux becomes very urgent problems.And the device for measuring forest soil respiration at present is ring
Shape, since root system in forest or chad are relatively more so that existing forest soil respiration measure ring installation is inconvenient, insecure, close
Envelope property is poor, directly results in measurement result and deviation occurs.
Utility model content
The purpose of this utility model is that solve the problems of the above-mentioned prior art, there is provided it is a kind of it is easy for installation firmly,
And the forest soil respiration sampler of good airproof performance.
A kind of forest soil respiration sampler, including it is PVC cylindrical, it is provided with into bottom PVC cylindrical equal
The insertion section of even dentation.
Further, forest soil respiration sampler as described above, is fixedly connected with cylinder PVC
One outer sleeve, is tightly connected between the outer sleeve and cylinder PVC.
Further, forest soil respiration sampler as described above, in the exterior outer spiral shell of setting PVC cylindrical
Line, in the internal thread that is internally provided with of outer sleeve, the outer sleeve is threadedly coupled for PVC with cylinder.
Further, forest soil respiration sampler as described above, a diameter of 20cm of cylinder PVC,
Highly it is 5-10cm；The height of insertion section is 5-10cm.
Beneficial effect：
The utility model material easily obtains, is simple in structure, is easy to use, removing and installing easy and good seal performance, energy
Enough ensure field continuous observation.
Brief description of the drawings
Fig. 1 is the utility model forest soil respiration sampler structure diagram；
Fig. 2 is the utility model forest soil respiration sampler part-structure schematic diagram.
Embodiment
To make the purpose of this utility model, technical solution and advantage clearer, below technical side in the utility model
Case is clearly and completely described, it is clear that and described embodiment is the utility model part of the embodiment, rather than all
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the present embodiment provides a kind of forest soil respiration sampler, including cylindrical PVC cylinders 2, in circle
The bottom of cylindricality PVC cylinders 2 is provided with into the insertion section 1 of uniform dentation.
Preferably, as shown in Fig. 2, forest soil respiration sampler as described above, on the cylinder PVC cylinders 2
An outer sleeve 3 is fixedly connected with, is tightly connected between the outer sleeve 3 and cylinder PVC cylinders 2.
Further, forest soil respiration sampler as described above, in order on the basis for guaranteeing accurately to sample
On, also realize the function being convenient for carrying, a diameter of 20cm of the cylinder PVC cylinders 2, is highly 5-10cm；The height of insertion section 1
Spend for 5-10cm.
Preferably, forest soil respiration sampler as described above, exterior in cylindrical PVC cylinders 2 set external screw thread,
In the internal thread that is internally provided with of outer sleeve 3, the outer sleeve 3 is threadedly coupled with cylinder PVC cylinders 2.
The utility model is simple in structure, easy to operate, and using PVC cylindrical, structure stress intensity is big, durable firm,
Measure sample is directly squeezed into the case where not destroying original forest soil and root system, two are connected above it with gas leaf chamber set
Carbonoxide infrared gas analyser measures soil respiration, using the dentation bottoms of PVC it is possible to prevente effectively from the chad in soil
With root system etc., improve seal, measurement accuracy is high, helps to study soil carbon discharge process, solve because of scientific research condition and
Caused by restriction, gained measured value can meet scientific research requirement, be particularly suitable for forest ecosystem field long term monitoring and use.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It can still modify the technical solution described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model technology
The spirit and scope of scheme.
