Description
Technical field
It the utility model is related to soil water experiment equipment technical field, more particularly to a kind of soil organic carbon mineralization culture dress
Put.
Background technology
Soil organic matter plays extremely important role in global carbon.Soil organic carbon mineralization is geobiont
Own metabolism is completed by own activity, decomposition and using organic carbon in soil, while discharges CO2Process, directly close
It is the release and supply and the maintenance of soil quality etc. of the nutrient into soil, is the key for influenceing plant growth and vegetation productivity
Factor.Disclose the effective control of scientific management and global warming of the rule of organic carbon mineralization in soil for nutrient etc. all
There is highly important practice significance.
The purpose of soil organic carbon mineralization culture experiment, is wanted in the analytical unit time caused by soil organic carbon mineralization decomposition
The amount of carbon dioxide, its principle are as follows:Organic carbon in soil, under aerobic conditions, by the effect of microorganism, most divide at last
Solve as CO2And H2O, the CO discharged2It can absorb in the sodium hydroxide solution of excess, the barium chloride of excess is added to hydrogen-oxygen
In the absorbing liquid for changing sodium, it is in barium carbonate sediment to make carbonate, is then titrated in sodium hydroxide absorbing liquid and remained with standard hydrochloric acid solution
Remaining alkali lye, according to above-mentioned reaction, you can calculate the CO that test sample is disengaged2Amount.Soil organic carbon mineralization measure is generally adopted
It is as follows with alkali liquor absorption titration, concrete operations：The soil of constant weight is put into wide-mouth bottle, added water to equivalent to for examination soil
The 60% of earth saturation moisture capacity, then the vial for filling sodium hydroxide is put into wide-mouth bottle, then screw the closure of bottleneck.
The incubator that wide-mouth bottle is placed in certain temperature is cultivated.During measure, bottle cap is opened, takes out the vial in blake bottle, together
When change to another vial for filling sodium hydroxide, capping continues to cultivate.Due to soil need to be maintained at for examination soil moisture content
The 60% of saturation moisture capacity, a deionized water is added for examination soil so generally being given every 2-3 days.In this way exist with
Some lower weak point：(1) bore of wide-mouth bottle is typically smaller than 70mm, be put into, take out fill sodium hydroxide vial and
It is inconvenient for operation during to for examination soil sprinkling deionized water；(2) wide-mouth bottle and the bottle equipped with sodium hydroxide are all glass system
Product, sodium hydroxide can react with glassware in experimentation；(3) when to deionized water is added for examination soil, often
Secondary bottle cap of opening can cause the carbon dioxide in air to enter in sodium hydroxide, cause experimental result bigger than normal；(4) due to cultivating
Cheng Zhong, wide-mouth bottle are constantly in air-tight state, when cultivation temperature is more than 25 DEG C, can be gone forward side by side for the moisture in examination soil by evaporation
Enter in sodium hydroxide, so as to reduce naoh concentration, cause experimental result deviation；(5), it is necessary to repeatedly open during testing
Closure, sealed tank cap can be caused to be reduced with tank body composition surface sealing property, cause the carbon dioxide in outside air to enter close
In sodium hydroxide in sealed cans, increase experimental result.
Utility model content
For technical problem present in above-mentioned prior art, this application provides a kind of soil organic carbon mineralization culture dress
Put.
To solve above-mentioned technical problem, the utility model uses following technical scheme：A kind of soil organic carbon mineralization training
Support device, including bore 90mm 1L plastic seals tank and respectively for trying soil, sodium hydroxide, deionized water are loaded on respectively
100ml, 50ml, 50ml plastic tank, the 1L plastics that 100ml, 50ml, 50ml plastic tank is together put into the bore 90mm are close
In sealed cans.
The beneficial effects of the utility model are:(1) bore 90mm 1L plastic seal tanks are used, are filled being put into, taking out
The vial of sodium hydroxide and during to for examination soil sprinkling deionized water, it is more easy to operate, and avoid hydroxide in experimentation
The problem of sodium can react with glassware；(2) will for examination soil, sodium hydroxide, deionized water respectively loaded on 100ml,
In 50ml, 50ml plastic tank, then three plastic tanks are together put into bore 90mm 1L plastic seal tanks, it is possible to reduce go from
The sprinkling number of sub- water, both reduced to the interference for examination soil, and also reduced Carbon Dioxide in Air and made into sodium hydroxide
Into experimental result deviation；(3) because in experimentation, neutralizing the water in the plastic tank equipped with deionized water for examination soil can lead to
Pervaporation enters in the plastic tank equipped with sodium hydroxide, so before the plastic tank equipped with sodium hydroxide is put into and taking-up
After weighed, with calculate determine when plastic tank in naoh concentration, reduce experimental bias；(4) sodium hydroxide is put into every time
After water is added, in the circumferential groove on sealed tank cap and tank body composition surface, smearing vaseline, then screwing hermetic tank are close
Capping, to increase sealing property.
