Small-sized automatic weighing type lysimeter
Technical field
The utility model relates to a kind of small-sized automatic weighing type lysimeter of measuring soil evaporation and plant transpiration, is particularly suitable for the long-term observation automatically of original position, belongs to hydrology, meteorology and agricultural ambit.
Background technology
For a long time, lysimeter enjoys the attention of related scientific research department as the necessary device of research soil evaporation and plant water consumption rule always.Lysimeter mainly is divided into large-scale lysimeter and small-sized lysimeter.Though large-scale lysimeter is owing to the volume that holds soil is bigger, can make the physicochemical property of soil in the container and the growthform of plant keep relative consistent, but because its equipment cost is higher, project scale is big with natural conditions, have immovability, be unfavorable for that the field installs whenever and wherever possible.And small-sized lysimeter is simple owing to its equipment, cost is low, and assay method is easy, is the focus that scholars study always.Traditional many employings of small-sized lysimeter reading of data (as the miniature lysimeter CN200820096811.6 of vega soil) of manually weighing, field operation is very inconvenient, personal error is also bigger, be not suitable for long-term Continuous Observation under the field condition, and traditional lysimeter needs to safeguard the round-the-clock lysimeter of weather such as rare suitable sleet at any time.Therefore, provide a kind of simple in structure, be convenient to install, automatic data collection and to be fit to the small-sized lysimeter of round-the-clock mensuration necessary for research soil evaporation and plant transpiration.
The utility model content
The purpose of this utility model is to provide the small-sized automatic weighing type lysimeter of the long-term ocean weather station observation of a kind of suitable original position, and continuous performance issue is lacked, lacked to the acquisition and recording data thereby overcome the cycle data that brings owing to observation inconvenience under the field condition automatically.
Solution of the present utility model is:
A kind of small-sized automatic weighing type lysimeter, this lysimeter be provided with LOAD CELLS, upper bracket, edaphophyte container, lower sleeve, the ground upper bracket is arranged on the above ground of above and below ground interphase, the ground lower sleeve is arranged in the following heatable adobe sleeping platform of above and below ground interphase, the LOAD CELLS level is installed on the ground upper bracket, the edaphophyte container is arranged at lower sleeve inboard, ground, and the edaphophyte container is suspended on the LOAD CELLS by suspension line.
Described small-sized automatic weighing type lysimeter, frame bottom is equipped with pin on the ground, and pin is inserted in ground.
Described small-sized automatic weighing type lysimeter, LOAD CELLS is at least two.
Described small-sized automatic weighing type lysimeter, rain cover is equipped with in the outside of LOAD CELLS.
Described small-sized automatic weighing type lysimeter, ground lower sleeve are permeable structures up and down.
Described small-sized automatic weighing type lysimeter, the bottom of edaphophyte container is drilled with osculum.
In the utility model, " small-sized " is meant: in the general assembly (TW) limit 200Kg of the soil that lysimeter can be measured, plant and edaphophyte container.
The beneficial effects of the utility model are:
The utility model can make things convenient for measures the edaphophyte evapotranspiration instantaneously, particularly is fit to open-air long-term in-site detecting, and simple in structure, be convenient to install.
Description of drawings
Fig. 1 is the stereographic map of an embodiment of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Among the figure, 1. rain cover; 2. LOAD CELLS; 3. upper bracket; 4. suspension line; 5. above and below ground interphase; 6. pin; 7. edaphophyte container; 8. osculum; 9. lower sleeve.
Embodiment
Shown in Fig. 1-2, the small-sized automatic weighing type lysimeter of the utility model mainly comprises: rain cover 1, LOAD CELLS 2, upper bracket 3, suspension line 4, pin 6, edaphophyte container 7, osculum 8, lower sleeve 9 etc., concrete structure is as follows:
The ground upper bracket is arranged on the ground of above and below ground interphase more than 5, and ground lower sleeve 9 is arranged in the heatable adobe sleeping platform of above and below ground interphase below 5.
Ground upper bracket 3 be used to install LOAD CELLS 2, ground upper bracket 3 bottoms be equipped with pin 6 (as the welding etc.), pin 6 is inserted in ground, with guarantee ground upper bracket 3 can firmly place ground.
LOAD CELLS 2 levels are installed on the ground upper bracket 3, generally use plural LOAD CELLS, and LOAD CELLS 2 requires to select according to measuring, and rain cover 1 is equipped with in the outside of LOAD CELLS 2.
Ground lower sleeve 9 be about permeable structures, be used to isolate the root system and the soil of surrounding plants, with the anti-tampering effect of weighing to edaphophyte container 7.
Edaphophyte container 7 is arranged at lower sleeve 9 inboards, ground, leave unsettled space between the heatable adobe sleeping platform bottom surface at the side of edaphophyte container 7 and bottom surface and ground lower sleeve 9 and lower sleeve 9 places, ground, the shape and size of edaphophyte container 7 are looked concrete research to be needed and the soil layering structural adjustment, the bottom of edaphophyte container 7 is drilled with osculum 8, osculum 8 is a plurality of, diameter 3-6mm.Edaphophyte container 7 horizontally suspends on LOAD CELLS 2 by suspension line 4, and LOAD CELLS 2 is connected with PC or data acquisition unit, can obtain soil evaporation and plant transpiration data message effectively.
