Description
Technical field
The utility model relates to a kind of soil permeability amount sampling apparatus.
Background technology
After World War II, countries in the world fertilizer amount increases severely.According to Food and Agricultural Organization of the United Nations (FAO) statistics, 1972 ~ 1973 years world's per hectare land equalization applied nitrogens 2.3 kilograms, 1.5 kilograms, phosphate fertilizer, 1.2 kilograms, potash fertilizer.Any kind of using in farmland and the chemical fertilizer of form, all can not all be absorbed and used by plants.Chemical fertilizer utilization ratio, nitrogen is 30-60%, and phosphorus is 2-25%, and potassium is 30-60%.Not by the nitrogen compound that plant utilizes in time, if exist with the form of the NH4-N that can not be adsorbed by soil colloid, will with under the holard that oozes be transferred to below root system dense layer and pollute.
The environmental problem that pollution by chemical fertilizer causes mainly contains:
(1), the eutrophication in rivers and creeks, lake, inland sea: along with using in a large number of chemical fertilizer, the utilization factor of fertilizer reduces widely, the chemical fertilizer of a large amount of unconverted utilization with water permeation in underground water, cause the eutrophication of river and lake water quality, especially the loss of nitrogen is the important root of groundwater contamination.
(2), soil polluted, and soil physical properties worsens.Excessive for a long time and use merely chemical fertilizer, can soil acidification be made.And directly affect the seed output and quality of agriculture production cost and crop.
Therefore, for effectively improving chemical fertilizer utilization ratio, environmental protect pollutes effectively, most important to the moving distribution dynamic research of element.In research process, the water collecting infiltration is generally adopted to carry out the method for analyzing and researching.
The device of existing collection soil permeability water, is and directly from soil layer, extracts water sample, be applicable to the soil that the water cut such as paddy field are higher, very undesirable compared with the effect of the soil permeability water of arid area to collection.
Utility model content
The utility model object is that the device collecting efficiency in order to solve existing collection farmland infiltration water sample is lower, is not suitable for the problem compared with arid area, provides a kind of soil permeability amount sampling apparatus.
Soil permeability amount sampling apparatus described in the utility model, it comprises water gathering tube, rotary seat, aqueduct, support, fixed plug, water leg and hanger, described water gathering tube sidewall is provided with water seepage hole, inside is filled with seepage material, one end of water gathering tube is cone, the other end of water gathering tube is arranged on rotary seat, rotary seat is driven by the output shaft of motor and rotates, aqueduct is " L " type pipe, water gathering tube is communicated with one end of aqueduct, the main body of the other end of aqueduct is fixed on the cross tube of support by fixed plug, two side levers of support are fixed with a hanger respectively, water leg is " U " type groove, the link of both sides is " n " type, water leg is suspended on two hangers by the link of both sides,
It also comprises switch valve and level sensor, and switch valve is arranged on aqueduct, and is positioned at the lower end of support cross tube, and level sensor is arranged on the upper end of water leg sidewall, and after level sensor detects water level signal, gauge tap valve cuts out.
Advantage of the present utility model: infiltration water sample collection tube of the present utility model adopts tapered tube, and be arranged on rotating base, increase the area of infiltration water sampling, improve the collecting efficiency of infiltration water sample, apply more extensive, be not only applicable to the higher soil of the water cut such as paddy field, also be applicable to comparatively arid area, and this apparatus structure is simple, is easy to carry, provide acquisition mode easily for gathering infiltration water sample.
