According to the environmental information collected by the temperature and humidity sensor, the temperature is controlled to be 28°C-32°C, and the humidity is controlled to be 50%-70%. The water in the hose pipe sprays water mist from the small hole through water pressure for humidification. S6. When the germination height of the rice seeds is 3-5 cm, the breeding tray is scooped up by the shovel plate of the breeding tray collection and release trolley, and the breeding tray is collected by the reverse rotation of the driving motor, and the seedling rolls in the breeding tray are collected and placed on the seeder for transplanting and sowing.
