Abstract
The utility model relates to a root system removal device for soil respiration measurement. The root system removal device comprises a cylindrical steel barrel, wherein small holes are uniformly formed in the side wall of the cylindrical steel barrel. The root system removal device is simple in structure and convenient to operate; the cylindrical steel barrel is adopted, so that the root system removal device is high in structure stress strength and durable and stable, and is directly driven into a measurement sample area for measurement under the circumstance of not destroying original soil and organisms; the transfer of air, soil colloid solutions, minerals and the like in soil cannot be limited by virtue of the small holes, so that the measurement accuracy is high, the study on a rhizosphere system and soil underground carbon distribution mechanism is facilitated, the restrictions caused by scientific and research conditions are eliminated, and the obtained measurement value can meet the scientific and research requirements; the root system removal device is especially suitable for long-term field monitoring.
Description
Technical field
The utility model dependent territory earth respiration monitoring technical field relates to a kind of root system remover, specifically a kind of root system remover of soil respiration mensuration.
Background technology
Global carbon and carbon revenue and expenditure are not only one of key problem of current climate change and Region Sustainable Development research, also are the themes of current a series of large-scale international co-operation scientific research plans (IGBP, WCRP, IHDP, GCTE and LUCC etc.).Soil is CO
2Important Yuan Hehui is the important ecological factor in the Global Biogeochemical Cycle, there are some researches show that carbon base in soil in the terrestrial ecosystems is 2 times of global atmosphere carbon storehouse, is 3 times of vegetation carbon storehouse.The variation of soil organic matter and inorganic carbon reservior is considered to cause the main cause of large gas carbon storehouse and Global climate change.
Important role, soil respiration CO are being played the part of in soil respiration in the carbonaceous subterranean cyclic process
2The size of burst size is the important indicator of estimation carbon base in soil dynamic change.The root system autotrophic respiration is the important composition part of soil respiration, affected by biology, abiotic factor, and soil respiration also presents corresponding variation.Root system respiration is reflecting also that to the response of whole world change soil respiration is to the respective degrees of whole world change.
At present, the comparatively general assay method of soil respiration is the amount of carbon dioxide that discharges from soil surface by direct or indirect mensuration, each method all has its benefit and limitation, because difference and the parameter of each assay method and technology are selected and space and time difference, accurate quantification to soil respiration causes scarcely determinacy, brings certain difficulty also for the comparability of the soil respiration emission flux data on the large scale space-time unique.At present, MAIN SOILS respiration monitoring method has following several: 1, indoor cultivation; 2, static chamber-vapor-phase chromatography; 3, static gas-CO
2Infrared gas analyzer (IRGA) method; 4, dynamic air chamber-CO
2Infrared gas analyzer (IRGA) method; 5, microclimate method (eddy covariance technique); 6, correlation analysis computing method (Indirect Determination).
The Components of Soil Respiration separation is respiratory rate or the ratio by direct or indirect each constituent of mensuration of distinct methods.In conjunction with present soil respiration measuring method, the research that relevant each composition of differentiation soil respiration divides mainly contains following technical measures: 1, root exclusive method; 2, root test tube method; 3, root biomass regression method; 4, composition overall approach; 5, tracer method.
Above-mentioned Components of Soil Respiration separating measure is devoted under existence conditions to distinguish in the soil respiration each component to the total contribution of breathing of soil with effective method, employed root system remover is the totally enclosed pvc pipe of tube wall, need to excavate soil puts into, destroy original soil texture, and the migration of the gas in the soil, soil colloid solution and mineral matter etc. is restricted, the accuracy that impact is measured causes the precision of quantitative examination soil carbonaceous subterranean balance inaccurate.
The utility model content
The purpose of this utility model provides the root system remover that a kind of soil respiration is measured, do not destroying the in site measurement of fixing a point in original soil and the biological situation, get rid of root system component respiratory components value in the separable soil respiration, be conducive to disclose Components of Soil Respiration and soil carbonaceous subterranean balance mechanism.
The technical scheme that the utility model adopts:
The root system remover that a kind of soil respiration is measured comprises cylindrical steel cylinder, and aperture evenly is set on the sidewall of cylindrical steel cylinder.Directly squeeze into when carrying out soil respiration and measure sample ground and can support the use the widely soil respiration of present domestic and international application and measure system (such as LI-8150) or portable light assembly system (such as LI-6400+09 leaf chamber) the soil carbon flux mensuration of being correlated with, because the fixed point original position is measured in the situation of not destroying original soil and biology, can make the migration of gas, soil colloid solution and mineral matter etc. in the soil unrestricted, prevent the intrusion of ground flora root system, increase the accuracy of measuring.
The diameter of described cylindrical steel cylinder is 25-30cm, the high 50-55cm of being.
The distribution density of the aperture on the described cylindrical steel cylinder is 1/4-6cm
2
The utility model is simple in structure, easy to operate, adopt cylindrical steel cylinder, structure stress intensity is large, durable firm, directly squeezing into mensuration sample ground in the situation of not destroying original soil and biology measures, utilize aperture can make the migration of gas, soil colloid solution and mineral matter etc. in the soil unrestricted, measurement accuracy is high, help to study Rhizosphere System and soil Total belowground carbon allocation mechanism, solved the restriction that causes because of scientific research condition, the gained measured value can satisfy the scientific research requirement, is particularly suitable for open-air long term monitoring and uses.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, cylindrical steel cylinder; 2, aperture.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing with by examples of implementation, but not as to restriction of the present utility model.
In the structure shown in the figure, the utility model comprises cylindrical steel cylinder 1, and the diameter 25cm of cylindrical steel cylinder 1, high 50cm evenly arrange aperture on the sidewall of cylindrical steel cylinder, and the aperture of aperture is 0.5cm, and distribution density is 1/4cm
2
Getting 3 ~ 5 cylindrical steel cylinder 1 horizontal intervals in selected good mensuration sample ground is that 2m(suitably adjusts in conjunction with sample ground soil is heterogeneous) 47 ~ 50cm vertically is driven underground; (reason has two: one, begins to measure after rotting etc. original root system of plant, to get rid of this interference again after installing 6 ~ 12 months; The 2nd, recover original situation and measure in soil texture) can support the use the widely soil respiration of present domestic and international application and measure system (such as LI-8150) or portable light assembly system (such as LI-6400+09 leaf chamber) the soil carbon flux mensuration of be correlated with.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
