A lower humidifying device and a temperature control device communicating with the first layer and the outside are fixedly installed on the light-transmitting outer shell. The second layer is hemispherical, so that the second layer can achieve the effect of concentrating light and increasing temperature. A cooling device and an upper humidifying device are fixedly installed inside the second layer. This technology discloses that "the device integrates functions such as light control, temperature control, humidity control, and ventilation control. By coordinating operations, it can simulate various types of adverse environments such as high temperature and high humidity, high temperature and dryness, low temperature and low light, and strong light stress. By designing combinations according to the requirements of the experiment, various extreme climate environments can be created, which is not limited by years and time.

[0047] In this embodiment, the stirring plate 20 facilitates accelerating the air mixing speed in the heating box 3, making the temperature in the heating box 3 more uniform.

[0048] Working principle and usage process of the present utility model: When it is necessary to screen planting resources, the seeds of crops are placed in the soil of the planting box 13. The screening box 1 is made of transparent material, which is convenient for observing the growth status of the seeds in the screening box 1. The screening box 1 is closed through the top cover of the screening box 1. Light is provided by the lighting lamp 14. Water is atomized by the humidifier 15 to water the seeds in the screening box 1. The temperature control device main body 16 is used to sense the temperature in the screening box 1. By setting a specified temperature, it is convenient to test whether the crops have high-temperature resistance. When the temperature in the screening box 1 is lower than the specified temperature, the temperature control device main body 16 controls the fan 5 and the heater 4 to start. The air in the heating box 3 is heated by the heater 4. The hot air in the heating box 3 is extracted by the fan 5, so that the hot air enters the fan 5 through the air inlet pipe 6. The hot air is sent into the air outlet pipe 7 by the fan 5. Subsequently, the hot air is shunted to various parts in the fixed pipe 9 through a number of first shunt pipes 8, making the hot air distribution in the fixed pipe 9 more uniform. The hot air in the fixed pipe 9 is shunted by the second shunt pipe 10, and the hot air in the second shunt pipe 10 is shunted through the air outlet pipe 11, so that the hot air is evenly dispersed to various parts in the screening box 1 through a number of air outlet pipes 11, thereby accelerating the mixing speed of the hot air and the air in the screening box 1, improving the uniformity of the temperature in various parts of the screening box 1, facilitating the improvement of the temperature control accuracy of the device main body, facilitating the improvement of the accuracy of the experimental results, and thus improving the accuracy and reliability of the planting resource screening. When the air in the heating box 3 is heated by the heater 4, the air temperature near the heater 4 is relatively high, while the air temperature far from the heater 4 is relatively low, which is likely to reduce the uniformity of the hot air entering the screening box 1. When the present device is in use, when the heater 4 heats the air, the motor 18 is started. The transmission shaft of the motor 18 drives the rotating rod 19 to rotate, thereby driving a number of stirring plates 20 to rotate. The air in the heating box 3 is stirred by the stirring plates 20, promoting the air flow in the heating box 3, thereby accelerating the heat transfer speed in the heating box 3, making the hot air temperatures in different regions of the heating box 3 relatively uniform, thereby improving the uniformity of the hot air entering the screening box 1, further improving the uniformity of the temperature distribution in different regions of the screening box 1, further improving the temperature control accuracy of the device, and further improving the accuracy and reliability of the planting resource screening.
