Abstract
The utility model discloses an experimental device for measuring the soil mineralization potential in large batches. The experimental device comprises soil sample containers, leacheate containers and a suction filtration device, wherein liquid guide pipes are connected between the leacheate containers and the soil sample containers; the liquid guide pipes are connected with flow controllers; and the soil sample containers and the suction filtration device are connected through the liquid suction pipes. In the experimental device, the liquid guide pipes provided with the flow controllers are connected between the leacheate containers and the soil sample containers, so that the flow velocity and the flow rate of leacheate can be well controlled; the soil sample containers and the leacheate containers are respectively arranged on a sample holding layer and a leaching device holding layer of a testing bracket, so that a plurality of samples can be measured at one time, and the experimental device is more time-saving, labor-saving and efficient compared with the conventional testing manner; and in addition, the soil moisture content can be adjusted through the extraction of a vacuum pump, so that the accurate water content control can be achieved, the manual labor can be saved further, and the work efficiency can be improved.
Description
Technical field
The utility model relates to a kind of experimental provision of batch testing mineralising gesture, belongs to the laboratory and uses the testing equipment technical field.
Background technology
Drip washing cultivation in gap is by the Soil Nitrogen mineralising gesture assay method of extensive employing.This method extracts existing inorganic nitrogen in the soil through constantly in the pedotheque of cultivating, adding leacheate, takes to control the mode of hydraulic pressure afterwards, soil moisture content is adjusted to optimum condition continues to cultivate, and this process need consumes great amount of time.At present, in the experimental implementation process, mostly leacheate is to add through the hand-held dropper of laboratory technician, and single can only be operated 1-2 sample, and this has not only reduced work efficiency, and manpower also is great waste.Cause puzzlement for the detection of Soil Nitrogen mineralising potentiality, be difficult to large-scale application.
Summary of the invention
The technical matters that the utility model will solve provides a kind ofly can control the leacheate flow, and can control soil moisture content easily, can also realize once measuring the experimental provision of the batch testing mineralising gesture of a plurality of samples, can overcome the deficiency of prior art.
The utility model solves the technical scheme that its technical matters adopted: it comprises the soil sample container containing, drenches liquid container containing and suction filtration device; Be connected liquid conduits drenching between liquid container containing and the soil sample container containing; On liquid conduits, be connected with flow controller, be connected through liquid suction pipe between soil sample container containing and the suction filtration device.
Described soil sample container containing is one or more with the quantity of drenching the liquid container containing, and more than one soil sample container containing is placed on respectively on the sample placed layer and leaching device placed layer of test bracket with pouring liquid container containing.Liquid suction pipe is made up of arm and house steward, and arm one end is connected with the leakage mouth of soil sample container containing respectively, and the other end all is connected on the house steward.
On the suction filtration device, be connected with vacuum meter and pressure control valve.
Described soil sample container containing is identical with syringe solution splendid attire tubular construction with the structure of drenching the liquid container containing, can use in test syringe solution splendid attire pipe to substitute.
Compare with prior art, the utility model passes through at the liquid conduits that drenches connecting band flow controller between liquid container containing and the soil sample container containing, but like this with regard to better controlled leacheate flow velocity and flow; With a plurality of soil sample container containings with drench the liquid container containing and be placed on respectively on the sample placed layer and leaching device placed layer of test bracket, but like this with regard to a plurality of samples of single-time measurement, have now relatively test mode save time more, laborsaving, efficient; The adjusting of soil moisture content is extracted through vacuum pump, and vacuum pump is connected with the suction filtration device, on the suction filtration device, connects vacuum meter and pressure control valve, can realize water percentage control accurately like this, can further save manpower, increases work efficiency.Liquid suction pipe is connected and composed by arm and house steward, so just can the draining of a plurality of soil sample container containings be accomplished with a cover suction filtration device, can reduce cost like this, conserve space.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment 1: as shown in Figure 1; A plurality of soil sample container containings 1 are placed on respectively on the sample placed layer 6 and leaching device placed layer 7 of test bracket with pouring liquid container containing 2; Between the port of the liquid outlet that drenches liquid container containing 2 and soil sample container containing 1, be connected liquid conduits 4, on liquid conduits 4, be connected with flow controller 5; Can adopt syringe solution splendid attire pipe as soil sample container containing 1 and pouring liquid container containing 2 respectively in the laboratory, the liquid conduits 4 of band flow controller 5 can use the woven hose of intercepting to substitute.Suction filtration device 3 is made up of vacuum pump and airtight container; Vacuum pump is connected on the airtight container; On airtight container, be connected with simultaneously vacuum meter, pressure control valve and liquid suction pipe, liquid suction pipe is made up of with house steward 9 arm 8, and arm 8 one ends are connected with the leakage mouth of soil sample container containing 1 respectively; The other end all is connected on the house steward 9, and house steward 9 is connected with airtight container.
In this example the airtight container of suction filtration device with two lid rubber stoppers bottle,suction replace; Connect with sebific duct between two bottle,suctions; On the stopper of each bottle,suction, open two holes; Two holes among Fig. 1 on the bottle,suction of left side connect vacuum pump 10 and vacuum meter respectively, and two holes on the bottle,suction on right side connect house steward 9 and baroswitch 11 respectively.
Its concrete operating process excessively is: will be connected with liquid conduits 4 (processing with woven hose) with the pouring liquid container containing 2 that syringe is processed; The pouring liquid container containing 2 that is connected with liquid conduits 4 is placed on the upper strata-leaching device placed layer 7 of test bracket; Lower floor's 1-sample placed layer 6 is placed the soil sample container containing 1 that culture sample is housed, and in drenching liquid container containing 2, behind the adding leacheate, opens flow controller 5; Adjust to suitable flow velocity, carry out the drip washing of sample.With rubber stopper sealing on soil sample container containing 1 upper end cover of drip washing, the bottom was connected with the arm 8 of liquid suction pipe after drip washing finished, and house steward 9 water delivering orifice and suction filtration device join, and vacuumized after connection finishes, and realized the soil moisture content adjusting.
