Abstract

The utility model relates to an ecological observation instrument for soil measurement and observation, and aims at providing a multifunctional small lysimeter. The multifunctional small lysimeter provided by the utility model comprises a soil column container, a base and a weighing platform sequentially connected from top to bottom, wherein a leakage device is arranged in the base; the upper end of the leakage device is covered with a leakage film; the surface of the soil column container is provided with multiple rows of sensor insertion holes from top to bottom; and the sensor insertion holes are used for inserting an oil temperature, moisture, water potential and profile carbon dioxide monitoring sensor and a soil solution sampler. The multifunctional small lysimeter provided by the utility model measures the data including temperature, moisture, water potential, soil profile carbon dioxide, plant stem flow and the like at different layers of soil while measuring the weight change of the soil column, and realizes diverse functions.

Description

The multifunctional small-size lysimeter

Technical field

The utility model relates to a kind of device of soil DATA REASONING, particularly relates to a kind of multifunctional small-size lysimeter.

Background technology

Lysimeter is an important soil ecology monitoring instrument, by precise monitoring and analysis earth pillar weight to original position soil-plant cartridge system, soil moisture, with research SOIL CARBON AND NITROGEN water circulation, comprise water balance, material balance, Water Transport, solute transfer, the transpiration soil ecology situation such as evapotranspire, be fit to the farmland, the grassland, forest, riverine wetland, the marsh, the root cellar for storing things, the long term monitoring of the ecosystems such as building foundation, be widely used in agronomy, forestry, environmental protection, meteorological, the hydrology, the research fields such as water conservancy, because of its system complex, so volume is relatively huge, be not easy to mobile, some small-sized portable lysimeters are arranged in the market, put down in writing by the 20102051587.X patent document such as application number, only has the edaphophyte container, the devices such as LOAD CELLS, can realize soil moisture is changed, the detection that material changes, but the variation of just measuring moisture and material is inadequate to analyzing the soil ecology situation, because the ecologic regime of soil needs many-sided data, affected by several factors, such as temperature, soil water retention degree etc., so existing portable small-sized lysimeter function is too dull, can not satisfy the detection that soil ecology is changed various data.

The utility model content

The technical problems to be solved in the utility model provides a kind of multifunctional small-size lysimeter.

The utility model multifunctional small-size lysimeter, comprise the earth pillar container, base and the weighing unit that connect successively from top to bottom, establish leak device in the described base, described leak device upper end is coated with the seepage film, described earth pillar vessel surface offers many row's sensor jacks from top to bottom, and described sensor jack is used for plugging the soil moisture, moisture, the flow of water, section carbon dioxide monitoring sensor, soil liquid sampler.

Compared with prior art the utility model offers many row's sensor jacks from top to bottom at the earth pillar vessel surface, the sensor jack is used for plugging the soil moisture, moisture, the flow of water, section carbon dioxide monitoring sensor, soil liquid sampler, can measure simultaneously the data such as material composition, soil layer root system development situation of the temperature of observing different soil, moisture, the flow of water, section gas flow, the soil liquid, than more comprehensively understanding the soil ecology situation, than the transpiration of the understanding soil and plant of science and the evaporation of moisture.

The utility model multifunctional small-size lysimeter, wherein said leak device is funnel-form, described leak device bottom is communicated with aqueduct, the described aqueduct upper surface that is connected with described leak device is provided with the diafiltration plate, adopt this kind structure to prevent soil loss, the water that oozes out in the soil layer is assembled, drainage is gone out, in time measure the infiltration situation of soil, can prevent the electronic scale in the moisture damage weighing unit.

Below in conjunction with accompanying drawing the utility model multifunctional small-size lysimeter is described further.

Embodiment

As shown in Figures 1 and 2, the utility model multifunctional small-size lysimeter comprises the earth pillar container 1 that connects successively from top to bottom, base 3 and weighing unit 4, establish leak device 2 in the base 3, leak device 2 is funnel-form, leak device 2 upper ends are coated with seepage film 22, leak device 2 bottoms are communicated with aqueduct 23, aqueduct 23 upper surfaces that are connected with leak device 2 are provided with diafiltration plate 21, earth pillar container 1 surface offers many row's sensor jacks 5 from top to bottom, is used for plugging the soil moisture in the sensor jack 5, moisture, the flow of water, section carbon dioxide monitoring sensor, soil liquid sampler.

The utility model multifunctional small-size lysimeter; can be laboratory and open-air the use; earth pillar container 1; leak device 2; the parts such as base 3 and weighing unit 4 can split as required and be used in combination; be easy to carry; diverse in function; can also install protective cover additional on its surface; can be placed on the utility model under the rugged surroundings and use for a long time; the utility model in use; get one with the identical earth pillar of earth pillar container 1 length in the measurement place; can also be coated with vegetation on the earth pillar; earth pillar is placed in the earth pillar container 1; in sensor jack 5, insert required sensor according to the data that will survey; sensor other end connection data collecting unit; analyze again after collecting data; thereby can learn the temperature of different soil; humidity; stemflow; the situations such as gas section distribution; leak device 2 can be collected the water that earth pillar in the earth pillar container 1 oozes out aqueduct 23 and discharge; diafiltration plate 21 and seepage film 22 can prevent that the soil property in the sealing flows away with water; to conserve water and soil; weighing unit 4 under the base 3 can weigh up earth pillar moisture and substance weight variation in the earth pillar container 1 very accurately like this; calculate more accurately the transpiration of the plant of soil percolation and upper soll layer, comprehensively the ecological condition of reflect soil.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
