Problems solved by technology

[0004] However, the cultivation and planting in the prior art generally has the problem of inconvenient adjustment of the cultivation environment. The general rice seedling cultivation device only provides a fixed light environment for the seedlings, and it is not convenient to adjust the light distance in different time periods, and the variable light The cost is high and it is difficult to use on a large scale; at the same time, during the cultivation process, manual operations such as adding fertilizer and water are required, and the workload is relatively large, and the water quality in the cultivation pot will deteriorate after a long time, which will also affect the growth of seedlings
