The utility model provides a rice cultivation device which can adjust the water level of rice and the height inside the device according to the rice in different periods. However, the existing rice cultivation device needs to add different amounts of nutrient solution according to its growth cycle to help its growth during the cultivation process. Currently, most of them add nutrient solution to the rice one by one manually, and the amount of nutrient solution added is not easy to control. In addition, the water storage and drought resistance capacity of rice cultivation is low, which affects the cultivation effect of rice.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0005] In view of the above problems, an innovative design is carried out on the basis of the original rice cultivation device. Summary of the invention
