Abstract
Description
Technical Field
[0001] This utility model is a hydroponic rice cultivation device, belonging to the field of rice cultivation technology. Background Technology
[0002] Hydroponic rice cultivation is an agricultural production technology that uses specially designed floating biological beds to cultivate rice without soil substrates. This technology uses floating beds made of chemical materials as a carrier, fixing seedlings through planting holes, and utilizing eutrophic water for natural nutrient supply, reducing the need for artificial fertilization and pest control. Hydroponics is widely used in various rice research projects due to its excellent controllability. A good hydroponic system is crucial for the success of indoor experiments.
[0003] Publication number CN223040726U mentions a rice hydroponic device. A motor drives a screw to rotate, and the rotating screw causes the fixed tube to move vertically due to the influence of the rotating thread and the limiting post. This causes the fixed frame to move upwards, exposing the rice roots inside the hydroponic tube or extending to the lower end of the tube, facilitating observation of rice growth. However, after use, each hydroponic tube requires manual cleaning, which is cumbersome. Furthermore, evaporation causes a drop in the liquid level, potentially exposing the roots and reducing seedling quality. There is an urgent need for a rice hydroponic device to solve these problems.
