Abstract
The utility model discloses a sleeve lysimeter, which comprises a lysimeter inner cylinder, a lysimeter outer cylinder, rubber gasket rings, a weighting sensor and a concrete base, wherein the lysimeter outer sleeve is fixed on the concrete base; the weighting sensor is fixed at the bottom of the lysimeter outer cylinder; the lysimeter inner sleeve is fixed on the weighting sensor; and the rubber gasket rings are connected to the tops of the lysimeter inner cylinder and the lysimeter outer cylinder. The sleeve lysimeter reduces the difference between the temperature of soil in the cylinders and the temperature of external field soil, and decreases the distance between the lysimeter cylinders and the external soil to enable soil in the same layer can exchange heat via heat radiation, and besides, the lysimeter cylinders are isolated with a basement, influence of the basement on the temperature of the lysimeter cylinder is lowered as soon as possible, therefore, the temperature of the soil in the lysimeter approximates that of the soil in the external field soil, and the growth environment of plants in the cylinders approximates natural conditions.
Description
Technical field
The utility model belongs to the lysimeter technical field, particularly a kind of telescopic lysimeter.
Background technology
Lysimeter (Lysimeter) is an instrument of measuring evaporation from land or evapotranspiration and soil moisture seepage speed and leakage; Since can be continuously directly weighing steam the weight change of oozing an interior soil body, be to evapotranspire and the reference instrument and the method for rainfall and soil moisture vertical movement in mensuration ground.The factor that influences the soil animal and plant growth is a lot, soil texture, the soil texture, moisture content supply, aeration, temperature etc.In these factors; Soil texture; We can make that soil property is close with the land for growing field crops in the cylindrical shell through undisturbed soil filling or artificial on demand proportioning the soil textures etc., and the difference of temperature factor will be brought inside and outside the cylindrical shell very big-difference of animals and plants and microorganism, thereby influences the evapotranspiration data.
Under the identical situation of soil property, temperature plays important effect to the growth and the plant of root system of plant to absorbing of soil moisture.At present, domestic a lot of lysimeter users build the very big basement of volume, and steaming is oozed cylinder and directly is placed in basement.There is very large difference in the indoor temperature of basement with normal field soil temperature with the degree of depth, and this directly influences the interior earth pillar temperature of cylindrical shell and field soil creates a difference.The lysimeter user is abroad arranged, and the soil moisture at basement installation constant temperature air conditioning, changes the extraneous soil moisture of basement temperature following with consistent with degree of depth field soil temperature synchronously in the earth pillar in order to make.So, increased system complexity, increased equipment investment and operating cost, only if outside the special research project needs, the general user is beyond affordability
Summary of the invention
The utility model fundamental purpose is in order to address the above problem; A kind of difference that reduces the interior soil moisture of cylindrical shell and extraneous field soil temperature is provided; Reduce the distance of the lysimeter cylindrical shell body and the extraneous soil body as far as possible; Make with layer soil body by the heat radiation heat-shift, keep apart lysimeter cylindrical shell and basement simultaneously, reduce basement as far as possible the temperature effect in the lysimeter cylindrical shell; Make the inner soil moisture of lysimeter and extraneous field soil temperature approaching, guarantee the growing environment and the approaching telescopic lysimeter of natural situation of tube implants.
In order to achieve the above object, the technical scheme that the utility model provides is: a kind of telescopic lysimeter, and it comprises lysimeter inner core, lysimeter urceolus, rubber seal, LOAD CELLS and concrete bed; The lysimeter urceolus is fixed on the concrete bed, and LOAD CELLS is fixed in the outer tube bottom of lysimeter; The lysimeter inner core is fixed on the LOAD CELLS; Top between lysimeter inner core and the lysimeter urceolus is connected with rubber seal;
The material of lysimeter urceolus is steel plate or concrete;
Distance is 30mm-100mm between lysimeter inner core and the lysimeter urceolus.
The size of the utility model, we can need by the user, and evaporation area is 1M
2, 2M
2, 4M
2The high 1M of earth pillar, 2M, 3M, or fully by the customization size, the gap between lysimeter inner core and the lysimeter urceolus, as far as possible little under the prerequisite that can satisfy the construction and installation requirement, at we 1M
2In the lysimeter, this spacing is 40mm; Can accomplish to be not more than 100mm for large tracts of land lysimeter again, reduce the distance of the lysimeter inner core and the extraneous soil body, make the inner soil moisture of lysimeter and extraneous field soil temperature approaching with minimizing; Rubber seal is arranged at lysimeter inner core and lysimeter urceolus top, and space and extraneous space between lysimeter inner core and the lysimeter urceolus are isolated fully.
