Description
Technical field
The utility model relates to a kind of fertilizer nutrient dissolution rate determinator, belongs to soil fertilizer science field.
Background technology
Sustained-controll-release fertiliser utilizes physics or chemical method to change fertilizer self character, thus reduce fertilizer dissolution velocity, extends plant to the term of validity of nutrient uptake and utilization, belong to one of new-type fertilizer.Sustained-controll-release fertiliser has raising utilization rate of fertilizer, reduces nutrient loss, alleviates improper fertilization to plurality of advantages such as the pollution of environment and simplification measures of fertilizer.The nutrient release rate of sustained-controll-release fertiliser and fertilizer efficiency period are two crucial judge index of reflection sustained-controll-release fertiliser quality.At present, the detecting and assessing method of sustained-controll-release fertiliser nutrient release rate and fertilizer efficiency period is numerous, as soil dissolution rate method, diffusion and permeability rate method, electro ultrafiltration method and isotope method etc. have been used to detecting and assessing sustained-controll-release fertiliser Nutrient Properties all.Wherein, soil dissolution rate method considers the diversity of soil colloid on the own environmental baseline of nutrient ion, molecular adsorption and soil to the impact of sustained-controll-release fertiliser nutrient release rate, comparatively close with the actual service condition in field, be therefore considered to the method that can reflect the Nutrient Release of sustained-controll-release fertiliser in field soil.
In order to measure sustained-controll-release fertiliser nutrient soil dissolution rate better, need to use soil eluviation simulator to measure sustained-controll-release fertiliser nutrient dissolved percentage.But because the operation of existing soil eluviation simulator is too complicated and can not meet the demand that multiple native fish carries out testing simultaneously, be therefore not easy to large quantities of sustained-controll-release fertiliser sample tests.In addition, the leaching column bottom of existing soil eluviation simulator can not be dismantled, and the soil be added in leaching post is difficult to take out, and is unfavorable for the cleaning of sampling and device.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide simple, the easy dismounting of a kind of structure and is convenient to the fertilizer nutrient dissolution rate determinator of cleaning.
For achieving the above object, the utility model takes following technical scheme: a kind of fertilizer nutrient dissolution rate determinator, is characterized in that: it comprises a fixed support, and described fixed support removably arranges multiple leaching post; Described leaching post comprises a leaching pipe, and the lower end of described leaching pipe and is fastenedly connected in the funnelform large end drenching pipe; Described drench in pipe be provided with one for placing the waffle slab of Soil and Fertilizer potpourri.
Described fixed support is a framed structure, comprises the two-layer fixed station be oppositely arranged, described fixed station is arranged at intervals with multiple fixed orifice; A stationary pipes be connected with described fixed orifice is fastenedly connected in the upper end of described leaching pipe.
Described stationary pipes, described leaching pipe and describedly drench pipe and all adopt PVC plastic to make.
Described fixed support adopts stainless steel material to make.
In the junction of described stationary pipes and described leaching pipe and described leaching pipe and the described junction drenching pipe, sealed by band.
The utility model is owing to taking above technical scheme, and it has the following advantages: 1, leaching post of the present utility model removably connects due to each several part, therefore when filling sample and cleaning leaching post more for convenience.2, fixed support of the present utility model is owing to being provided with fixed station and being provided with fixed orifice on fixed station, therefore can carry out batch sample determination test, improves test efficiency.3, the utility model apparatus structure simple, be easy to installing/dismounting, operating process is convenient and practical.
Accompanying drawing explanation

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises a fixed support 1, dismountablely on fixed support 1 arranges multiple leaching post 2.Wherein, leaching post 2 comprises a leaching pipe 22, and the lower end of leaching pipe 22 and is fastenedly connected in the funnelform large end drenching pipe 23.Be provided with one for placing the waffle slab 24 of Soil and Fertilizer potpourri drenching in pipe 23.
In above-described embodiment, fixed support 1 is a framed structure, comprises the two-layer fixed station 11 be oppositely arranged, fixed station 11 is arranged at intervals with multiple fixed orifice 12.A stationary pipes 21 is fastenedly connected, because stationary pipes 21 diameter is greater than leaching pipe 22 diameter, therefore, it is possible to be fixedly connected with it after making leaching pipe 22 penetrate fixed orifice 12 in the upper end of leaching pipe 22.
In above-described embodiment, seal by teflon seal tape, to prevent leaching liquor seepage with the junction drenching pipe 23 in the junction of stationary pipes 21 and leaching pipe 22 and leaching pipe 22.
In above-described embodiment, stationary pipes 21, leaching pipe 22 and drench pipe 23 and all adopt PVC plastic to make.
In above-described embodiment, fixed support 1 adopts stainless steel material to make.
The utility model operationally, first nylon net cloth is positioned on waffle slab 24, then in the leaching pipe 22 of leaching post 2, add the sand of 25g, add the soil of 100g again as cushion, soil reinstalls the wind desiceted soil of 400g and the uniform mix of fertilizer, finally at a small amount of silica sand of earth pillar surface coverage in case leaching time upset soil layer.Be inserted into after leaching post 2 has been filled in the fixed orifice 12 of fixed support 1, and fixed by stationary pipes 21 and fixed orifice 12.Then placing a leaching liquor receiving flask below the small end going out pipe 23 in the pouring of leaching post 2 and collect test specimen, for measuring nutrient content in leaching liquor, calculating fertilizer dissolution rate.
The various embodiments described above are only for illustration of the utility model; wherein the structure, connected mode etc. of each parts all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
