Description

Technical Field

[0001] The utility model relates to a liquid level control mechanism, in particular to a nutrient solution tank liquid level control mechanism for deep liquid flow cultivation, belonging to the technical field of deep liquid flow cultivation. Background Art

[0002] In the deep liquid flow cultivation system, the plant roots are directly immersed in the nutrient solution, and the roots absorb nutrients and water in the nutrient solution to meet the growth needs. Compared with traditional soil cultivation, this cultivation method has higher efficiency and controllability. Since the cultivated plants will continuously absorb water and nutrients, the liquid level of the nutrient solution will continue to drop. If the liquid level drops to a certain level, the plant roots may be exposed to the air, resulting in hypoxia and dryness, affecting the growth of the plants. For this reason, we propose a nutrient solution tank level control mechanism for deep liquid flow cultivation to solve the above problems. Utility Model Content
