Description
Technical field
This utility model relates to a kind of soil available nitrogen detection kit.
Background technology
Soil available nitrogen refers to the nitrogen that can be utilized by this season Crop rapidly in soil, mainly includes being present in soil
In earth aqueous solution or partial adsorbates on soil colloid granule by and nitrate anion, also small part can be the most absorbed by crops
The aminoacid of the little molecule utilized.The method measuring soil available nitrogen mainly has the direct culture method of soil (include aerobic and dislike gas
Cultivate) and the big class of chemical method two, chemical method is simple and quick, is suitable for conventional determining, and conventional has direct distilled nitriding, change
Learn extraction and alkaline hydrolysis diffusion method.There is presently no the chemical method measuring soil available nitrogen felt quite pleased, alkaline hydrolysis diffusion method is also
Claim Kang Wei ware diffusion method, be that current China applies to compare a kind of mensuration soil available nitrogen widely simple and quick method.
Its ultimate principle is to use certain density aqueous slkali, within specified temperatures, the organic nitrogen of facile hydrolysis in soil can be made to hydrolyze
For ammonia, also make by being converted into ammonia, and absorbed by boric acid solution.By this boric acid solution of standard acidometric titration, according to the consumption of standard acid
Amount just can calculate the amount of boric acid institute absorbing ammonia, that is the nitrogen quantity of soil alkaline hydrolysis diffusion.
If the content of nitrate anion in soil to be measured, then while adding aqueous slkali, reduction must be added to soil
Material, as every 2g soil adds the saturated solution of 0.2gFeSO4 7H2O and 0.1mlAg2SO4, increases the concentration of alkali simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of convenient test, accurately a kind of soil available nitrogen detection kit.
For achieving the above object, this utility model provides following technical scheme:
A kind of soil available nitrogen detection kit, including box body and the lid that is tightly connected mutually with this box body, its feature exists
In: be provided with the round turntable of one and this inboard wall of cartridge sliding contact in described box body, the central shaft hole of described round turntable with set
The output shaft being placed in the electric rotating machine bottom this round turntable fixes connection, and described round turntable is refractory ceramics matrix or gold
Belonging to matrix, its upper surface covers connection to be had Electric radiant Heating Film, the upper end of described round turntable also to shelve to be provided with diffusion boat, on described lid
It is provided with the filling opening corresponding with the mistress of described diffusion boat.
Preferably, above-mentioned a kind of soil available nitrogen detection kit, wherein said Electric radiant Heating Film includes the most successively
Inner insulating layer, thick film circuit zone of heating and external insulation layer.
Preferably, above-mentioned a kind of soil available nitrogen detection kit, wherein said electric rotating machine is interior with described box body
Fill between wall and be provided with vibration-absorptive material.
Preferably, above-mentioned a kind of soil available nitrogen detection kit, wherein said vibration-absorptive material is polyurethane foam.
Preferably, above-mentioned a kind of soil available nitrogen detection kit, wherein said lid is additionally provided with vacuum orifice.
Relatively prior art, this utility model Advantageous Effects is mainly reflected in: traditional soil available nitrogen is straight when detecting
Connect the quantitative sample uniform spreading that accurately weighs in diffusion boat mistress, then rotate diffusion boat with hands gently, make sample pave,
In traditional operating process, anthropic factor is too much, operation inconvenience, directly uses electric rotating machine to drive circle to turn in this technical scheme
Dribbling is moved diffusion boat and is rotated, and uses electric heating film to control the temperature in test process, and temperature control is simple and convenient, easily operates, and adopts
Arranging filling opening with lid, it can more preferably ensure the sealing property between lid and box body.
Accompanying drawing explanation
Fig. 1: this utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in further detail, so that technical solution of the present invention is more
Should be readily appreciated that and grasp.
As it is shown in figure 1, a kind of soil available nitrogen detection kit, including box body 1 and the lid that is tightly connected with this box body 1 phase
Body 2, is provided with the round turntable 3 of one and this box body 1 inwall sliding contact, the center of described round turntable 3 in wherein said box body 1
Axis hole is fixing with the output shaft of the electric rotating machine 5 being arranged at bottom this round turntable 3 to be connected, and described round turntable 3 is high temperature resistant
Ceramic matrix or metallic matrix, its upper surface covers connection has Electric radiant Heating Film, the upper end of described round turntable 3 also to shelve and be provided with diffusion
Ware 4, described lid 2 is provided with the filling opening 8 corresponding with the mistress 9 of described diffusion boat 4.
Wherein said Electric radiant Heating Film includes inner insulating layer, thick film circuit zone of heating and external insulation layer the most successively.
Fill between wherein said electric rotating machine 5 and the inwall of described box body 1 and be provided with vibration-absorptive material 6.
Wherein said vibration-absorptive material 6 is polyurethane foam.
It is additionally provided with vacuum orifice 8 on wherein said lid 2.
During traditional soil available nitrogen detection directly by the quantitative sample uniform spreading that accurately weighs in diffusion boat mistress, so
Rotating diffusion boat afterwards with hands gently, make sample pave, in traditional operating process, anthropic factor is too much, operation inconvenience, this technology
Scheme directly uses electric rotating machine drive round turntable to drive diffusion boat to rotate, and use electric heating film to control in test process
Temperature, temperature control is simple and convenient, easily operates, and use lid filling opening is set, it can more preferably ensure between lid and box body
Sealing property.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
