Abstract
The invention relates to a crop root zone day and night temperature difference control system which mainly comprises a fluid circulation pipe, a temperature sensing element, a heat storage box, a cold storage box, a fluid heating and cooling device, a temperature display, a temperature controller, pipelines and circuits, wherein the fluid circulation pipe, the temperature sensing element and the heat storage box are arranged in a crop root zone, and the pipelines are mutually connected with the circuits. The system sets the operation temperature of the temperature controller according to different varieties of crops and the optimum day and night temperature needed by the crops in different periods, the day temperature and the night temperature which are different are provided for the crop root zone, the effective day accumulative temperature of the crops is maximized, respiration-based consumption of the crops at night is minimized, crop yield and quality are improved, and limit of distribution of existing crops is broken.
Description
Technical field
The present invention relates to plant husbandry, especially with to plant crops and mushroom in earth's surface closely related.
Background technology
Temperature, directly affect growth, growth, output, quality and the limit of distribution of crops, and day and night temperature is the key of higher yield of crops.Existing plant husbandry does not arrange Crop Root district day and night temperature control system, crops root zone temperature can only change with surface soil, and soil temperature, with temperature and hysteresis temperature Change, causes root zone temperature not increase daytime, crops are vigorous state in Asia, and organic matter accumulation is inadequate; Night, temperature was unable to come down, and crops are in semidormancy state, and organic substance consumption is too much, therefore, had suppressed the raising of crop yield, had limited the Regional Distribution of crops.
Summary of the invention
The object of the invention is to control the day and night temperature in Crop Root district, for the coring of crops provides an optimum temperature environment, allow crops draw Nutrients uptake photosynthesis daytime as far as possible, accelerate organic matter accumulation; Complete dormancy at night, reduces organic substance consumption, impels crops effective accumulated temperature on daytime to maximize, and night, respiration consumption minimized, and reaches raising crop yield and quality so that breaks through the object of existing crops limit of distribution.
Solution of the present invention is such:
Fluid circulation tubes (2) and temperature-sensing element (3) are set in Crop Root district (1); Fluid circulation tubes import (4) one end is connected with heat storage box (8) through ebullator (6), and the other end is connected with cool-storing box (12) through ebullator (14); Fluid circulation tubes outlet (5) one end is connected with heat storage box through ebullator (7), and the other end is connected with cool-storing box (12) through ebullator (13), then one end is connected with retaining valve (11); Temperature-sensing element (3) connects fluid heating, refrigerating plant (9) and ebullator (6), (7), (13) and (14) again after being connected with temperature indicator (15) and temperature controller (10), the heating part of fluid heating, refrigerating plant is connected with heat storage box, and refrigerating part is connected with cool-storing box; Set the operating temperature of temperature controller with the required optimum temperature round the clock of crops different times of living in, system between round the clock around two kinds of different design temperature alternate runs.
The present invention has the following advantages:
The coring that Crop Root district day and night temperature control system is crops provides an optimum temperature environment, crops daytimes can vigorous growth, dormancy completely at night, growth, the organic matter accumulation of crops are accelerated, the effective accumulated temperature of crops is fulfiled ahead of schedule, yield and quality is improved, and the limit of distribution of existing crops will give breakthrough.
Accompanying drawing explanation:
Fig. 1 is the vertical view of Crop Root district day and night temperature control system, and Fig. 2 is A-A cut-open view, and Fig. 3 is B-B cut-open view; (1) be Crop Root district, (2) are fluid circulation tubes, and (3) are temperature-sensing element, (4) be fluid circulation tubes import, (5) are fluid circulation tubes outlet, and (6), (7) are ebullator, (8) be heat storage box, (9) are fluid heating, refrigerating plant, and (10) are temperature controller, (11) be retaining valve, (12) are cool-storing box, (13), (14) be ebullator, (15) be temperature indicator, (16), (17), (18) and (19) are valve, and (20) are fluid.
With reference to the accompanying drawings, with regard to embodiments of the invention, be further described:
As shown in the figure, fluid circulation tubes (2) and temperature-sensing element (3) are set in Crop Root district (1), fluid circulation tubes import (4) one end is connected with heat storage box (8) through ebullator (6), and the other end is connected with cool-storing box (12) through ebullator (14); Fluid circulation tubes outlet (5) one end is connected with heat storage box through ebullator (7), and the other end is connected with cool-storing box (12) through ebullator (13), then one end is connected with retaining valve (11); Temperature-sensing element (3) connects fluid heating, refrigerating plant (9) and ebullator (6), (7), (13) and (14) again after being connected with temperature indicator (15) and temperature controller (10), the heating part of fluid heating, refrigerating plant is connected with heat storage box, and refrigerating part is connected with cool-storing box; The method of operating of Crop Root district temperature control system: 1. according to crops different times of living in required optimum temperature round the clock, set the operating temperature of temperature controller; 2. two kinds of situations and running program: if A. crops root zone temperature is lower than design temperature, valve-off (18) and (19), open valve (16) and (17), the heating part of fluid heating, refrigerating plant and ebullator (6), (7) can be opened automatically, and hot fluid (20) heats Crop Root district by fluid circulation tubes; In the time that root zone temperature reaches design temperature, heating arrangement and ebullator (6), (7) stop automatically; If B. root zone temperature is higher than design temperature, valve-off (16) and (17), open valve (18) and (19), open automatically the refrigerating part of fluid heating, refrigerating plant and ebullator (13) and (14), cold fluid (20) is lowered the temperature to Crop Root district by circulation pipe, in the time that crops root zone temperature reaches design temperature, cooling process stops automatically; 3, add thermal change cooling: first valve-off (17), valve-off (16) again after the hot fluid in fluid circulation tubes all returns to heat storage box, then opens valve (18) and (19) and enters cooling process; 4. cooling becomes heating: first valve-off (18), valve-off (19) again after cold fluid all returns to cool-storing box, then opens valve (16) and (17).
Crop Root district day and night temperature control system, can accelerate growth and the growth of crops, improves the yield and quality, and is expected to break the limit of distribution of existing crops.
