In, one is placed in setting the constant incubator of cultivation temperature.Soil Trace Gases emission monitoring can be by certain time
The gaseous sample in closed container is gathered within section, is contained by specific greenhouse gases in gas chromatography analysis gaseous sample
Amount, is changed with time by gas content to calculate rate of discharge.Soil incubation and the perfect condition of gas sampling are sealings
Ventilation is good in preceding incubator, and gas mixture ratio is more uniform after sealing, and the sample obtained in sample collection is representative, energy
Enough distribution situation of the image study gas in container.But in practical study, gaseous sample mainly passes through in culture vessel
Syringe connection sampling pipe is manually or by suspension built-in fans mixing, and manually air blast is taken a breath, to a certain degree
On internal gas or culture sample are interfered（Such as temperature caused by fan electromotor fever raises, sample surfaces structure
By flow perturbation etc.）, and in terms of mixed effect there are it is certain the defects of.Meanwhile sample collection mainly passes through one end open
Straight tube complete, main collection accumulates in the larger sample of incubator bottom density, thus sample collection representativeness is not good enough, to grinding
There is the influence that can not ignore in the accuracy for studying carefully result.Similar research is such as：Deng Bangliang etc., Increases in
soil CO2 and N2O emissions with warming depend on plant species in restored
Alpine meadows of Wugong Mountain, China, 2016, Journal of Soils and Sediments,
16（3）：777-784.The research of Deng Bangliang etc. carries out sample mixing and sampling only with the air collecting pipe of one end open,
Disturbed in the presence of to culture sample, gas mixing is uneven, the possibility of the representative deficiency of gas sampling.
