Description

Technical Field

[0001] The present invention belongs to the technical field of testing equipment for planting, and specifically relates to a testing device for regulating temperature and humidity in a planting environment for plants and a testing method thereof. Background Art

[0002] During the cultivation process of tea plants, it is often necessary to obtain the best cultivation parameters, especially temperature and humidity control, detect and adjust key parameters such as temperature and humidity, compare the growth of plants and tea leaves in each round, and conduct quality inspections of tea leaves under different parameters to determine the best temperature and humidity values ​​for plant growth. Usually, a temperature and humidity adjustment test device for the plant planting environment is used for testing.

[0003] The plant planting environment temperature and humidity adjustment test device in the prior art needs to replenish water to the plants regularly to maintain normal growth and cultivation during use. However, in the actual water replenishment process, irrigation water replenishment is usually adopted, which makes the soil compacted and the air permeability weakened, affecting the normal growth of the plants. When drip irrigation or other irrigation schemes are adopted, a large amount of water is directly attached to the surface of the branches and leaves during the test due to interference from the branches and leaves of the plants. The water flow on the surface of the branches and leaves is difficult to be quickly absorbed by the soil, and the humidity in the test box is increased during evaporation, thereby affecting the set humidity value in the test box, interfering with the adjustment test, and reducing the test accuracy. In addition, due to the influence of the dense branches and leaves of the plants, the upper and lower spatial connectivity of the plants is low, and the internal temperature and humidity are unevenly distributed, which affects the temperature and humidity detection accuracy and the comprehensive adjustment test effect is poor.

[0022] (1) The present invention realizes the rotation of the rotating rod in the actuator component by utilizing the cooperation of the composite power unit and the rotating unit. The liquid supply is supplied by the gravity of the water flow of the liquid supply component. In cooperation with the rotation of the rotating rod, the slit of the actuator component is intermittently opened, so that the filled liquid intermittently drips through the slit to simulate the effect of rainwater. In cooperation with the assembly position of the actuator, the water flow is directly dripped and acts on the soil below the leaves of the plant and close to the top of the planting soil, completing accurate drip irrigation treatment and avoiding soil compaction caused by direct irrigation. At the same time, in cooperation with the water replenishment process, the liquid droplets are dispersed on the leaves of the plant, and the dripping water flow is directly absorbed by the soil to avoid the water droplets dispersed on the leaves of the plant affecting the control of the humidity in the test box, ensuring the humidity stability, and conducting plant cultivation tests under fixed temperature and humidity.

During intermittent drip irrigation, repeated collision vibration is used to accelerate the dripping of liquid droplets at the bottom of the slit mouth to avoid hanging on the wall for too long, thereby further improving the drip irrigation effect.

[0024] (3) The present invention reuses the composite power unit and the actuator component, and cooperates with the suction effect of the suction component. During the test, the suction component sucks the air in the actuator component, and cooperates with the rotation of the rotating rod to intermittently inhale air from the bottom of the plant leaves and guide it to the space above the plant, so as to achieve full mixing of the air above and below the lush leaves of the plant, improve the uniformity of the air inside the test box, and ensure that the temperature sensor and the humidity sensor accurately obtain the accurate temperature and humidity in the test box, thereby ensuring that the temperature and humidity in the test box are accurately controlled, and adaptively adjusted according to the changes in temperature and humidity, ensuring that the temperature and humidity inside the test box are at the target temperature and humidity for plant cultivation, realizing regular growth detection of tea leaves, and the actual adjustment test has high accuracy and good effect.

[0025] (4) Through the above-mentioned effects, when the actual humidification component is replenishing humid air, the present invention ensures that the humid air is quickly and evenly distributed in the test box through the air flow and mixing in the test box, achieving uniformity after adjustment, avoiding local high or low humidity, and achieving good use effect.
