Centralized seedling raising can enable some crops that are relatively fragile in the seedling stage to safely pass through the seedling stage until they can survive independently. The use of cultivation boxes for centralized seedling raising can increase the germination rate and survival rate of crops, thereby improving agricultural production efficiency; planting experiments can obtain crop growth data and screen excellent plants in order to improve crops.

The soil is placed in the box body, the seeds are sown in the soil in the box body, and the lamp is used for supplementary light. However, the existing crop cultivation boxes can only control the light and the temperature of the growth environment. Due to the large variety of crops and the many environmental factors that affect the growth of crops during their growth, simply changing the light and the temperature of the growth environment is not enough to meet the requirements of seedling cultivation and planting experiments.
