Description
Technical field
The utility model relates to a kind of paddy rice high temperature stress treating apparatus.
Background technology
In recent years, global extreme weather is frequently existing, and various natural calamity takes place frequently, and the Climatic regionalization in meteorological disaster causes huge threat to Rice Production.Correlative study shows, rice yield is with the temperature rises in negative correlativing relation, tracing it to its cause, is because paddy rice is very responsive to high temperature at reproductive stage, wherein responsive with heading flowering period, if this period meets with high temperature, paddy rice grain husk flower development will be suppressed, cause grain husk flower fertility to decline, even cause grain husk to be spent time serious sterile, directly affect the ripening rate of paddy rice, finally cause the paddy rice underproduction and even total crop failure.Because paddy rice Climatic regionalization occurs unpredictable, once Abnormal Summer High Temperature can occur, avoid paddy rice Climatic regionalization by prevention, almost cannot realize, this should propose requirement by paddy rice Climatic regionalization to by seed selection heat-proof water rice varieties.Particularly in the last few years, research finds that the warm tolerance of hybrid rice is poor, and the impact by Climatic regionalization is larger, and Food Security in China has been arrived in the serious threat of heat evil.
The research of paddy rice heat evil is in the starting stage at present, although achieve the achievement that some are gratifying, but no matter be hot harmful appraisement system, or research method is all immature, with regard to current report, the method for hot harm reason is varied, does not have unified standard, therefore how improving high-temperature processing method is urgent problem, is the research most important thing from now on.
Paddy rice Climatic regionalization serious threat Rice Production, but the high-temperature processing method adopted at present utilizes the Electric heating such as air-conditioning and heated quarty tube to regulate indoor temperature, its weak point is: can only regulate warm indoor air temperature, do not consider that in fact water temperature is larger on the impact of rice varieties warm tolerance, does not therefore simulate the experimental condition that in grow actual with paddy rice, field conditions is identical completely.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of paddy rice high temperature stress treating apparatus.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of paddy rice high temperature stress treating apparatus, comprises glass greenhouse, pond, water circulation system, automatic temperature control system, heating and cooling device;
Pond is arranged in glass greenhouse;
Water circle device comprises pump, inlet channel, outlet conduit and cyclic water tank; Inlet channel is connected with the water inlet by pond, and outlet conduit is connected with the delivery port in pond, and pump drives current one-way circulation in water circulation system;
Inlet channel is provided with heating and cooling device;
Automatic temperature control system comprises temp probe and fin; Temp probe is separately positioned in pond with in glass greenhouse; Above the wall surrounding that fin is arranged on glass greenhouse and pond.
As preferably, pond is that cement is built, and pond volume is dark 1m, long 10m, wide 1m.
As preferably, heating and cooling device comprises heater and refrigerating plant; Heater adopts electrical heating; Refrigerating plant adopts compression-type refrigeration.
The beneficial effects of the utility model are:
By effectively controlling water temperature and air themperature, can the actual growing state in round-the-clock simulated rice land for growing field crops, eliminate the problem that greenhouse high temperature treatment condition cannot be homogeneous, a water temperature difficult problem cannot be regulated and controled when solving high temperature treatment simultaneously, and at aberrant summer low temperature with overcast and rainyly also can carry out high temperature treatment, improve accuracy and the repeatability of test.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model paddy rice high temperature stress treating apparatus embodiment.
Embodiment
As shown in Figure 1, a kind of paddy rice high temperature stress treating apparatus, is made up of glass greenhouse, pond, water circulation system, heating and cooling device, automatic temperature control system.
The glass greenhouse of 30 square meters between is built with glass wall and glass roof.Have 2 ponds of building with cement side by side in glass greenhouse, each sump area is 10 square meters, dark 1 meter.
The width leaving aisle between 2 ponds is 0.6 meter, 1 meter, pond distance glass wall.
The side of pool wall of pool is provided with water inlet, and at the bottom of pond, height is 0.6 meter, at the bottom of the pond of pond opposite side, be provided with delivery port.
The inlet channel of water circulation system is connected with the water inlet on cement pit.The outlet conduit of water circulation system is connected with the delivery port at the bottom of cement pit, is equipped with one-way cock at water inlet and delivery port, and cement pit is intake from water inlet, from delivery port water outlet.
The inlet channel of water circulation system is connected with cyclic water tank by pump with outlet conduit.In pump driving water circulation system, current are from pond outlet to pond water inlet one-way circulation.
Heating and cooling device is provided with at the inlet channel of water circulation system.Wherein heater adopts Electric heating, and refrigerating plant adopts compression-type refrigerating system.Heating and cooling device is heated by current inlet channel inside being flowed to cement pit or cools to change inflow temperature, finally reaches the object changing water temperature in pond.
Automatic temperature control system carries out work by temp probe, and temp probe is divided into water temperature to pop one's head in and air probe two kinds, is located at respectively in pond and in glass greenhouse.
