DETAILED DESCRIPTION

[0025] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0026] like Figure 1 As shown, the utility model provides a simulated climate chamber for studying stress resistance of organic crops, comprising a chamber body 1, wherein a plurality of cultivation troughs 2 are provided at the inner bottom of the chamber body 1, wherein the cultivation troughs 2 are used to place cultivation soil for organic crops, so as to cultivate organic crops in the cultivation troughs 2;

[0027] In this embodiment, a pH sensor 3 is installed in the cultivation tank 2 to detect the pH value of the soil in the cultivation tank 2 to study the growth of organic crops in soils with different pH values;

[0028] In this embodiment, the inner wall of the box 1 and the inner wall of the cultivation tank 2 are both installed with temperature and humidity sensors 4 for detecting the temperature and humidity conditions in the box 1 and the soil to study the growth of organic crops under different temperature and humidity conditions;

[0029] In this embodiment, a transparent window 15 is embedded in the front face of the box 1 for observing the growth of organic crops in the box 1;

[0030] In this embodiment, a fan 5 is embedded in one side of the box 1, and an exhaust port 6 facing the air outlet of the fan 5 is opened on the other side of the box 1 to simulate natural wind and evaluate the impact of wind on crops.

[0031] Among them, the exhaust port 6 is hinged with a switch door 7, which is convenient for the wind to flow in the box body 1 after the switch door 7 is opened, so as to better simulate natural wind;

[0032] In this embodiment, two air supply pipes 8 are embedded in the top of the outer side of the box body 1. The two air supply pipes 8 are connected to the external cold air production equipment and hot air production equipment respectively. The cold air and hot air are transported into the box body 1 through the air supply pipes 8 to simulate the growth of organic crops at different temperatures.

[0033] like Figures 1 to 5 As shown, in this embodiment, a delivery pipe 9 is rotatably mounted on the inner top of the box body 1, and an arc-shaped track 10 is locked and fixed on the inner wall of the box body 1;

[0034] Several atomizing nozzles 11 for drainage are installed at the bottom of the delivery pipe 9, and a hollow plate 16 is installed at the right end of the outer side of the delivery pipe 9;

[0035] A sliding frame 12 is slidably mounted on the curved track 10. The sliding frame 12 can move along the curved track 10 so that the lighting lamp 13 can illuminate different positions of the organic crops. The lighting lamp 13 is locked and fixed at the bottom of the sliding frame 12, and a first motor 14 is fixed to the front end surface of the sliding frame 12. The output shaft of the first motor 14 passes through the outer surface of the sliding frame 12 and is connected to a roller 19 built into the sliding frame 12. The roller 19 is in rolling connection with the curved track 10, so that the roller 19 can be driven to rotate by the first motor 14, so that the roller 19 drives the sliding frame 12 to move along the curved track 10 when it rotates.

[0036] The hollow plate 16 has an eccentric wheel 17 movably connected thereto. The inner ring of the eccentric wheel 17 is connected to the output shaft of the second motor 18 installed on the box body 1, so that the second motor 18 drives the eccentric wheel 17 to rotate and push the hollow plate 16 to swing back and forth.

[0037] The outer diameter of the eccentric wheel 17 is smaller than the inner length of the hollow plate 16, so that the eccentric wheel 17 can push the hollow plate 16 to swing back and forth in the box body 1 when the eccentric wheel 17 rotates.

[0038] Specifically, the position of the box 1 is adjusted so that the arc track 10 extends in the east-west direction, and the delivery pipe 9 is connected to the external water source delivery equipment through a hose;

[0039] When in use, the lighting lamp 13 is started to simulate the effect of sunlight on organic crops. The second motor 18 can be started to drive the roller 19 to rotate. When the roller 19 rotates, it drives the sliding frame 12 to move along the curved track 10. The sliding frame 12 drives the lighting lamp 13 to move. By controlling the rotation speed of the output shaft of the second motor 18, the movement cycle of the sliding frame 12 on the fixed guide rail 10 is approximately 12 hours. When the lighting lamp 13 moves, it simulates the lighting conditions of sunlight on organic crops at different time periods.

[0040] Water can be transported into the delivery pipe 9 and sprayed downward through the atomizing nozzle 11 to act on the organic crops, so as to simulate the impact of rainy weather on the organic crops. Starting the first motor 14 can drive the eccentric wheel 17 to rotate. When the eccentric wheel 17 rotates, it pushes the hollow plate 16 to swing back and forth. The hollow plate 16 can drive the delivery pipe 9 to swing back and forth. The delivery pipe 9 can drive the atomizing nozzle 11 to swing back and forth, so that the atomizing nozzle 11 can spray water onto the organic crops at different positions, which is conducive to making the organic crops more evenly affected by rain, so as to evaluate and cultivate the adaptability and tolerance of organic crops under environmental pressures such as temperature, wind speed, precipitation, and light, so as to better study the stress resistance of organic crops.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
