[0029] As Figure 1 shown, the water level controllable plant cultivation device 1000 comprises a water tank 1, a cultivation tank 2, a water inlet assembly 3, a drainage assembly 4 and a humidity sensor 5, the water tank 1 is provided with a water storage cavity 11, the water inlet assembly 3 and the drainage assembly 4 are connected with the water storage cavity 11 respectively, the water inlet assembly 3 is used for feeding water to the water storage cavity 11, the drainage assembly 4 is used for draining water in the water storage cavity 11, so as to control the water level height of the water storage cavity 11 through the cooperation of the water inlet assembly 3 and the drainage assembly 4.

[0030] Further, the incubator 2 is arranged in the water storage cavity 11 and has a gap relative to the bottom of the water storage cavity 11, the incubator 2 is provided with a culture cavity 21 for laying soil 22 to culture plants, the bottom wall and / or the side wall of the incubator 2 is provided with a water infiltration structure (not shown in the figure, the same below) for infiltrating water in the water storage cavity 11 into the culture cavity 21, the humidity sensor 5 is installed on the inner wall of the incubator 2 and is used to detect the water infiltration height of the culture cavity 21, and the humidity sensor 5 is also used to send a signal to open the drainage assembly 4 when the water infiltration height of the culture cavity 21 reaches a preset value.

[0031] It should be understood that the water infiltration structure refers to a structure that allows water in the water storage cavity 11 to infiltrate into the soil 22 in the culture cavity 21, the water infiltration height refers to the height of water infiltrating upward from the bottom of the soil 22 through the soil capillary characteristics, that is, the height of the soil 22 from the dry state to the wet state (when the soil 22 is fully infiltrated, the water infiltration height is equal to the height of the entire soil 22; when the soil 22 is partially infiltrated, the water infiltration height is equal to the height of the entire soil 22 minus the height of the dry soil 22 at the top), and the wet state of the soil 22 refers to a soil state that is conducive to the growth of terrestrial plants, not a state directly seeing the water level in the culture cavity 21, which can be detected by the humidity sensor 5 to detect the humidity change of the soil 22.

[0032] Please refer to Figure 1 and Figure 2 , the water level controllable plant culture device 1000 comprises a water tank 1 and an incubator 2, the incubator 2 is arranged in the water storage cavity 11 of the water tank 1 and has a gap relative to the bottom of the water storage cavity 11, water is supplied to the water storage cavity 11 through the water inlet assembly 3 or water in the water storage cavity 11 is drained through the drainage assembly 4, so that the water level height of the water storage cavity 11 can be flexibly controlled, and the water level can be adjusted to a state lower than the incubator 2 (as shown in Figure 1 ) or to a state of soaking the water infiltration structure of the incubator 2 (as shown in Figure 2When the water level of the water storage cavity 11 soaks the water-permeable structure of the incubator 2, the water can gradually permeate into the soil 22 in the culture cavity 21 through the water-permeable structure, starting from the bottom of the culture cavity 21, simulating the condition that the bottom of the real soil environment is wet and the upper part is dry, and the water-permeable height is accurately controlled by the humidity sensor 5. When the water-permeable height of the culture cavity 21 reaches the preset value, a signal is sent to start the drainage assembly 4 to drain the water in the water storage cavity 11 to end the water permeation. Not only can the water supply operation of the conventional plant be realized, but also a small amount of water can be provided at the bottom of the soil 22 to simulate the soil lacking water and fertilizer, which is beneficial to accurately screen or cultivate plants with different depth roots. Each time of water supply is through the water inlet assembly 3 to re-enter water, so that the water quality pollution problem does not occur, and the water quality meets the plant cultivation requirements. The structure is simple, efficient, low in cost, high in applicability, and can be used on a large scale.

[0033] Further, the humidity sensor 5 is also used to send a signal to start the water inlet assembly 3 when the humidity of the soil 22 in the culture cavity 21 does not reach the preset value. When the soil 22 is too dry, it can also be monitored by the humidity sensor 5 in time, and the water inlet assembly 3 is started in time for water supply, so that the state of the soil 22 meets the plant production requirements.

[0034] Further, the water-permeable structure includes a water-permeable hole opened on the incubator 2. The aperture, shape and number of the water-permeable hole can be adjusted according to the parameters of the soil 22. At the same time, the water-permeable hole is used for water permeation, and the soil 22 is prevented from leaking out along the water-permeable hole. In other embodiments, the water-permeable structure can also include a water-permeable film overlaid on the water-permeable hole, which isolates the soil 22 to prevent the soil 22 from flowing out.

[0035] Further, the incubator 2 is supported by a support frame (not shown, the same below) in the water storage cavity 11. The support frame can be specifically supported on the bottom or sidewall of the incubator 2. When the support frame is supported on the bottom of the incubator 2, the support frame is arranged on the bottom wall of the water storage cavity 11 to stably support the incubator 2. When the support frame is supported on the sidewall of the incubator 2, the support frame is connected with the inner sidewall of the water tank 1 or arranged outside the water tank 1, so as to avoid the support frame from being corroded or contaminated due to long-term water immersion, and improve the service life of the support frame. In other embodiments, a hanging bracket or a hanging rope can also be used to hang the incubator 2, and the incubator 2 is hung in the water storage cavity 11, so that the incubator 2 has a gap relative to the bottom of the water storage cavity 11, and the water permeation operation can be stopped conveniently.

The preset value refers to the water level that can immerse the water permeable structure and enable the water permeable structure to normally permeate water. When water permeation is needed, the water drainage assembly 4 is closed and the water inlet assembly 3 is opened, water is introduced through the water inlet assembly 3, and the water inlet assembly 3 is closed when the water level in the water storage cavity 11 reaches the preset value through the liquid level sensor, which can avoid water waste caused by excessive water level and can also avoid affecting the high-precision control of the water permeation height due to too fast water permeation speed.

[0037] It should be understood that in the present embodiment, when water permeation is performed, the water level of the water storage cavity 11 is lower than the water permeation height of the soil 22, and water permeation can be performed only by controlling the water level of the water storage cavity 11 to reach the water permeable structure. Accordingly, water permeation can be stopped only by controlling the water level of the water storage cavity 11 to be lower than the water permeable structure, and therefore the water level control precision requirement of the water storage cavity 11 is relatively low, and a low-precision liquid level sensor such as a float type liquid level sensor or a floating ball type liquid level sensor can be used for liquid level control, which has low cost, good stability and strong durability.

When performing plant cultivation, not only can the different water penetration heights be detected by the plurality of humidity sensors 5 to flexibly adjust the water level and meet the cultivation requirements of plants with different depth root systems, but also the water penetration situation can be analyzed by the detection data of the plurality of humidity sensors 5 to determine the range of soil height with sufficient water penetration and the range of soil height without water penetration, thereby providing accurate data for plant cultivation and facilitating the screening or cultivation of plant materials with deep root systems. Secondly, the overall humidity of the soil 22 can be monitored in real time by the plurality of humidity sensors 5 to confirm that the soil humidity data meets the plant growth regularity, which is convenient for laboratory researchers to record.
