Description
Technical field
The utility model relates to karst stuay field, is specifically related to a kind of monitoring device of soil carbon dioxide concentration.
Background technology
As shown in Figure 1, in the past to the research of the gas concentration lwevel gradient of different depth soil, due to the restriction of technological means, bury the probe 1 be placed in soil be very easily subject to the impact of soil moisture and scrap, (after rainfall 14 continuous during rainy season, soil moisture content raises, and even reaches capacity to cause monitoring to be interrupted, probe 1 is directly immersed in water, causes internal short-circuit of popping one's head in).And, the mode of directly excavation is adopted: first in the place needing to install probe 1 when installing probe 1, exclude plant and the dry branches and fallen leaves on earth's surface, with instruments such as spade, shovel, pick, soil is removed again, dig the required degree of depth, and then at different depth place, the side fluting in hole, probe 1 is installed, finally soil is backfilled.There is following defect in above-mentioned research mode: (1) is too large to the disturbance of soil, even if strictly backfill by undisturbed soil 2, also will the part soil constituent of new backfill, factor of porosity and undisturbed soil be caused widely different, when particularly having rainwash 3 to produce, the preferential interface 5 from undisturbed soil 2 and backfill soil 4 flows into soil horizon by rainwash 3, be similar to pipeline stream, instead of evenly infiltrate, the representativeness of monitoring result is had a greatly reduced quality.The result of study of going together in the world shows, due to the disturbance to soil, and the probe that this mode is installed, after generally will waiting half a year, or after the rainfall of more than six, wait soil natural closely knit to close to original state, monitoring result ability is representative; (2) be only applicable to monitor the soil of Arid&semi-arid area, as the words used in tropical, rainfall more regions, subtropics, only be useful in latter stage in rainy season and withered season monitors, now soil moisture content is lower, does not reach capacity, less to the infringement of probe, and when continuous rainfall in rainy season, because soil moisture content sharply rises, reach 80%-100%, easily make probe be immersed in for a long time in the holard and cause damaging.
Another field condition is also had to measure the mode of soil profile gas concentration lwevel, as shown in Figure 2, first couple together removing the detector tube after terminal 7 with hand-operating vacuum-pump 8 with one section of flexible pipe, the other end of detector tube 7 connects the flexible pipe 6 being about 50cm, then the dry branches and fallen leaves on earth's surface is pushed aside, the drill rod 10 with iron hammer 9 diameter being about 1.5cm pounds certain depth in soil, be generally 20cm or 50cm, then the drill rod 10 hammering designated depth into shape is extracted, rapidly the flexible pipe 6 connected is inserted in hole, and aperture grave is closed, finally form vacuum with hand-operating vacuum-pump 8, gas in extraction aperture is by detector tube 7, by the degree of the reagent reacting variable color in carbon dioxide and detector tube 7, the data that artificial interpretation is last.The defect of this method mainly contains: (1), in hammering drilling process, the soil of drill rod 10 pairs of hole wall peripheries exists dense extrusion effect, by the pore closure of hole wall periphery; In withered season, when soil moisture content is low, extremely difficulty creeps into darker position again; (2) when detecting gas concentration lwevel, close owing to only having near aperture, under vacuum, make the gas in whole hole, gas in even each deep soil layer likely enters into detector tube, the result of test is the concentration of mixed gas, cannot the soil carbon dioxide concentration of true representations certain depth; (3) detector tube consumptive material use amount is large; (4) reading is by manually carrying out interpretation according to reagent discoloration, and error is comparatively large, and precision is little.
Utility model content
In sum, in view of the defect of above traditional monitoring mode, in order to can be reduced to minimum to the disturbance of soil, the monitoring of soil carbon dioxide can be carried out again for a long time continuously in tropical and subtropical region, not by the impact of continuous rainfall on monitoring, technical problem to be solved in the utility model is to provide a kind of monitoring device of soil carbon dioxide concentration.
