Abstract
The utility model discloses a soil temperature controller. The overall soil temperature controller forms a flat box body, and is matched with a temperature controller and a compressor for use; soil is contained in the flat box body; the flat box body is formed by a foam plate wrapped by an iron sheet; a plate loop condenser pipe is arranged below an iron sheet bottom plate, and sequentially connected and matched with the compressor and a cooling fin outside the flat box body; a probe is inserted into the center position at the bottom inside the flat box body; the probe is externally connected with the temperature controller; a sun-proof heat-insulation sunshade aluminum foil is paved above the soil of the flat box body. The soil temperature controller can provide equipment guarantee and technical support for simulation of effects on crops caused by soil temperature by a researcher.
Description
Technical field
The utility model relates to a kind of crops ground temperature control instrument, refers in particular to the soil ground temperature controller for greenhouse by solar heat and booth.
Background technology
At present, greenhouse by solar heat has become the critical facility that northern China winter hard vegetable is produced, but because greenhouse by solar heat is generally without warming-up device, all improves indoor air temperature and ground temperature by savings solar energy.In the time of fine day, indoor air temperature raises rapidly, reaches very soon plant growth thermophilic, and the rising of soil temperature is comparatively slow, and therefore, low ground temperature obstacle has become the key factor of restriction Greenhouse in North fruit vegetables overwintering cultivation.At present, sunlight indoor envirobnmental control research is more with temperature aspect, but relatively less to the research of root zone temperature, and main cause is also not yet to have a kind of device that can simulate ground temperature and carry out correlative study.Based on above situation, develop a kind of instrument of simulating winter greenhouse soil ground temperature, be conducive to researcher and carry out this type of research.
Utility model content
The technical problems to be solved in the utility model has been to provide a kind of soil ground temperature controller, this controller is according to the top-down Temperature Distribution of Winter Solar Greenhouse soil layer, circulating condensing pipe processed snakelike dish is laid on to the active position of soil layer bottom, variations in temperature is identical mutually with Winter Solar Greenhouse from bottom to top to make soil layer.This controller can be to be carried out simulation ground temperature research a set of new equipment is provided, and affects crop growth mechanism technical support is provided for probing into soil temperature.
The technical problems to be solved in the utility model is realized by following scheme: soil ground temperature controller, entirety is flat casing, be used in conjunction with temperature controller, compressor, in flat casing, hold soil, it is characterized in that: described flat casing is made up of cystosepiment outsourcing iron sheet, dish circulating condensing pipe processed is set below iron sheet base plate, compressor, fin outside described dish circulating condensing Guan Yubian processed casing connect cooperation successively, probe is inserted in flat casing inner bottom part center, the external temperature controller of described probe, sunshade thermal insulation sunshade aluminium foil is laid in flat casing soil top.Flat casing inner bottom part four circles are fixedly added with angle steel.
The utility model has the advantages that: soil ground temperature controller is the simulation winter greenhouse soil temperature device of decline trend from top to bottom, is not affected by the external environment, and fluctuation is little, can adjust at any time temperature, its volume is little, mobile convenient, easy to operate.With the bottom-up transmission of dish circulating condensing pipe cold air processed, meet soil temperature feature in winter greenhouse, be applicable to very much carrying out the correlative study of simulated soil temperature aspect.Soil ground temperature controller is in control soil temperature process, as need control 10cm soil layer ground temperature, in flat casing, lay the thick test of 10cm with native, then seeding row spacing field planting trial crops on soil layer of the each concrete testing program of foundation, regularly water and topdress, temperature controller is adjusted to and requires temperature to start test.This pattern is simulated soil temperature effectively, and obtains good result of the test.Compressor, temperature controller and fin are fixed by the external support of flat casing.
Brief description of the drawings
Further describe embodiment below in conjunction with accompanying drawing
Fig. 1 is soil ground temperature controller schematic perspective view.
Embodiment
As shown in Figure 1, soil ground temperature controller entirety is flat casing 1, is used in conjunction with temperature controller 2, compressor 3, in flat casing 1, holds soil, and sunshade thermal insulation sunshade aluminium foil (not shown) is laid in top.Flat casing 1 is made up of cystosepiment outsourcing iron sheet, and length × wide × height is 100cm × 80cm × 30cm.Flat casing 1 inner bottom part four circles are fixedly added with angle steel 4.Bottom is the thick high-density foam plate 5 of 5cm.On cystosepiment 5 and between iron sheet base plate below, there is 3cm space, (pipe is apart from 5-8cm to be provided with snakelike dish circulating condensing pipe 6 processed, tubing is copper pipe, and caliber is Φ 8-12), compressor 3 and fin 7 that it is 70-80W that two ends are all stretched out with flat casing 1 external power are connected cooperation successively.Watertight transducer 8 is inserted in flat casing 1 inner bottom part center, and watertight transducer 8 is by 2 meters of external temperature controllers 2 of long line, and temperature controller 2 adopts electronic full-automatic digital display temperature controller SM3.
Claims (2)
1. soil ground temperature controller, entirety is flat casing, be used in conjunction with temperature controller, compressor, in flat casing, hold soil, it is characterized in that: described flat casing is made up of cystosepiment outsourcing iron sheet, dish circulating condensing pipe processed is set below iron sheet base plate, compressor, fin outside described dish circulating condensing Guan Yubian processed casing connect cooperation successively, probe is inserted in flat casing inner bottom part center, the external temperature controller of described probe, and sunshade thermal insulation sunshade aluminium foil is laid in flat casing soil top.
2. soil ground temperature controller according to claim 1, is characterized in that: flat casing inner bottom part four circles are fixedly added with angle steel.
