Technical field
This utility model relates to a kind of detection device, especially with regard to the determinator of a kind of soil alkali-hydrolyzable nitrogen.
Background technology
Soil alkali-hydrolyzable nitrogen is one of index of reflection Soil Nitrogen Supplying, is nitrogen fertilizer recommendation in fertilization compositions based on earth measurement
Important evidence.Alkali-hydrolyzable nitrogen includes the little molecule organic nitrogen of ammonium nitrogen and facile hydrolysis, such as: aminoacid, acyl ammonium and
Facile hydrolysis protein.The assay method of alkali-hydrolyzable nitrogen is to use base extraction soil, the organic nitrogen of facile hydrolysis and ammonium nitrogen
It is converted into ammonia, with boric acid absorbing ammonia, then uses standard acidometric titration, calculate hydrolyzable nitrogen content.Conventional method measures
Soil alkali-hydrolyzable nitrogen needs to use the diffusion boat of a kind of band cover glass, and diffusion boat is divided into interior mistress, generally in interior room
The middle addition boric acid solution containing indicator, mistress adds pedotheque to be measured and NaOH (sodium hydroxide), and with one
Block clouded glass cover plate covers diffusion boat.In order to prevent gas leakage, coat alkalescence glue at the mistress edge of diffusion boat.
But this diffusion boat exists following defect: 1, owing to interior mistress is adjacent and volume is shallower, cause the acid of interior room with outer
The aqueous slkali of room the most mutually pollutes；Readily diffuse in diffusion boat when 2, being coated with alkalescence glue at mistress edge, pollute
Sample or solution；3, the alkaline glue not easy cleaning at diffusion boat edge, impacts easily to next mensuration, surveys
Making existing error or mistake, need to be repeatedly measured to obtain result accurately, this gives operator or experiment point
Analysis process brings bigger burden and trouble；When 4, testing with this device, after adding aqueous slkali, ammonia
Diffusion needs 24 hours, due to overlong time, thus have impact on the determination efficiency of soil alkali-hydrolyzable nitrogen.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of soil testing efficiency and the high soil of accuracy
The determinator of earth alkali-hydrolyzable nitrogen.
For achieving the above object, this utility model takes techniques below scheme: the mensuration of a kind of soil alkali-hydrolyzable nitrogen fills
Put, it is characterised in that: it includes the bottle that an open at one end one end is closed, detachable at the bottleneck of described bottle
Ground connects a sealing lid, and the support extended inside described bottle by the described bottom sealing lid supports one
Hold ware.
Described support includes the many connecting rods being fastenedly connected with described close closure base portion, and many described connecting rods are altogether
With supporting a pallet；The described ware that holds is detachably connected on described pallet.
Described bottle uses glass to make.
The described lid that seals all uses resin material to make with described pallet.
Described support uses stainless steel material to make.
The capacity of described bottle is 460mL, a diameter of 90mm of described sealing lid, described pallet a diameter of
72mm, described in hold a diameter of 60mm of ware.
This utility model owing to taking above technical scheme, it has the advantage that 1, this utility model due to
The bottleneck of bottle detachably connected one seals lid, arrange in the bottom sealing lid one extend inside bottle
Frame, on support, detachably connected one holds ware, and wind desiceted soil sample the most to be measured and sodium hydroxide solution can be put
Being placed in bottle body bottom, the boric acid solution containing indicator can be positioned over and hold in ware, effectively prevent sodium hydroxide and
The mutual pollution of boric acid solution.2, this utility model decreases the pollution of soil alkali-hydrolyzable nitrogen mensuration process and artificially misses
Difference, improves soil testing efficiency and accuracy.3, the ware that holds of the present utility model is owing to detachably connecting with support
Connecing, and wind desiceted soil sample to be measured and sodium hydroxide are positioned over bottle body bottom, the boric acid solution containing indicator is positioned over
Holding in ware, therefore this device is easy to clean.This utility model can be widely applied in fertilization compositions based on earth measurement.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, this utility model includes that one is vertically arranged and the bottle 1 of open at one end one end closing, at bottle
