Description
Technical field
The utility model relates to a kind of leaching test device, belongs to soil investigation detection technique field.
Background technology
China be one populous, the large agricultural country of shortage of resources.Chemical fertilizer, agricultural chemicals occupy very important status in China's grain-production, are goods and materials investments maximum in peasant's productive investment.But heavy dressing year after year, spraying pesticide, some negative effects also display gradually, as phenomenons such as body eutrophication, soil compaction, disease incident increase, energy serious waste.The not important agricultural problem still such as Nitrogen In Soils element leaching loss, phosphorus element body eutrophication, heavy metal pollution, pesticide residual contamination, and be the major issue that threatens human health and existence.Therefore, in research soil the leaching of special component for preventing soil pollution, preserve the ecological environment significantly, also kind of a plant is had to valuable help effect.
Utility model content
The purpose of this utility model is to provide a kind of leaching test device, to can carry out leaching test for soil better.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of leaching test device, comprise demountable tube, support, receiving vessel, wherein, demountable tube is arranged on support, and support is arranged on receiving vessel, demountable tube bottom is provided with gauze parcel, the upper position of demountable tube installs and is equipped with internode and agrees with the square texture structure of structure and cross, and support inner side surface is provided with circular arch support, and receiving vessel oral area is provided with groove, circular arch frame bottom is provided with screw thread mouth bottle cap screw closure structure, and circular arch support agrees with by groove and receiving vessel.
In the utility model device, the every joint regular length of demountable tube is 5cm, and effect is splendid attire soil sample; Support effect is the weight of bearing demountable tube, and receiving vessel effect is to accept leaching liquor and bear demountable tube and the weight of support.Leaching test conventionally need to be cut the pipe of one to carry out partial analysis, works comparatively loaded down with trivial details, is also difficult to cut neatly simultaneously, is made demountable tube and test procedure can be simplified, and has the effect economizing on resources simultaneously.Every pipe joint bottom adopts 1/2nd groove structures and the square texture structure of cross, and its advantage is: 1/2nd groove dislocation are inserted, screwed, just can connect demountable tube; / 2nd grooves are outwarded winding, taken out, can disconnect demountable tube, the square texture structure of cross can fitly cut internode soil sample simultaneously.Holder part, circle arched structure holding capacity is stronger; The pipe of the interior swallow collocation 5cm of 5cm, can fix two sections of internode structures, reaches the effect of firm pipe.Screw thread mouth bottle cap screw closure structure, advantage is: the screw thread mouth structure of bottle cap can be strengthened holding capacity; Hollow out bottle cap can not affect water droplet and fall.Container part, can make container and use, and directly accepts leaching liquor, reduces the loss; Boundary groove is agreed with circular arch support, plays a supporting role; Container bottoms area is large, plays firm effect.
The beneficial effect of this utility model is: above test unit is easy to connect, contributes to carry out leaching test, and can economize in raw materials, and do not affect test structure, install comparatively firm, be convenient to test.

Description of symbols in figure: 1, demountable tube; 2, support; 3, receiving vessel; 4, internode agrees with structure; 5, the square texture structure of cross; 6, circular arch support; 7, screw thread mouth bottle cap screw closure structure; 8, groove.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, to better understand the utility model.
Leaching test device as shown in Figure 1 and Figure 2, comprise demountable tube 1, support 2, receiving vessel 3, wherein, demountable tube 1 is arranged on support 2, support 2 is arranged on receiving vessel 3, demountable tube 1 bottom is provided with gauze parcel, the upper position of demountable tube 1 installs and is equipped with internode and agrees with the square texture structure 5 of structure 4 and cross, support 2 inner side surfaces are provided with circular arch support 6, receiving vessel 3 oral areas are provided with groove 8, circular arch support 6 bottoms are provided with screw thread mouth bottle cap screw closure structure 7, and circular arch support 6 agrees with by groove 8 and receiving vessel 3.
In the utility model device, the every joint regular length of demountable tube 1 is 5cm, and effect is splendid attire soil sample; Support 2 effects are the weight of bearing demountable tube 1, and receiving vessel 3 effects are to accept leaching liquor and bear demountable tube 1 and the weight of support 2.Leaching test conventionally need to be cut the pipe of one to carry out partial analysis, works comparatively loaded down with trivial details, is also difficult to cut neatly simultaneously, is made demountable tube 1 and test procedure can be simplified, and has the effect economizing on resources simultaneously.Every pipe joint bottom adopts 1/2nd groove 8 structures and the square texture structure 5 of cross, and its advantage is: 1/2nd groove 8 dislocation are inserted, screwed, just can connect demountable tube 1; / 2nd grooves 8 are outwarded winding, taken out, can disconnect demountable tube 1, the square texture structure 5 of cross can fitly cut internode soil sample simultaneously.Holder part, circle arched structure 6 holding capacity are stronger; The pipe of the interior swallow collocation 5cm of 5cm, can fix two sections of internode structures, reaches the effect of firm pipe.Screw thread mouth bottle cap screw closure structure 7, advantage is: the screw thread mouth structure of bottle cap can be strengthened holding capacity; Hollow out bottle cap can not affect water droplet and fall.Container part, can make container and use, and directly accepts leaching liquor, reduces the loss; Boundary groove 8 is agreed with circular arch support 6, plays a supporting role; Container bottoms area is large, plays firm effect.
The process that uses said apparatus to test is as follows:
(1) this device is installed from bottom to top.
(2) orlop tube coupling bottom is sealed with nylon gauze, get 2 qualitative filter papers and be laid on pipe filling cloth, then add the about 2cm of silica sand thick, then soil sample is packed in pipe.
(3) by experiment increase in demand tube coupling number, screw in tube coupling, add soil sample.
(4) to be installed to final section, add after soil sample, place again at soil sample top the silica sand that about 2cm is thick, mouth of pipe upper end need stay about 1cm deep space as the use of pouring water.
(5) Xiang Guanzhong adds deionized water 200ml balance 48h.
(6) add the each 150mL of certain density nutrient solution, infiltrate 24 h.
(7) carry out leaching 3 times with the deionization moisture of 450ml, leaching interval time is 24 h.
(8) each tube coupling is from top to bottom outwarded winding and taken off successively, incline and soil sample, can measure each soil layer total nitrogen content.Repeat 3 times, with mean value mapping, investigate its migration situation in soil.
