Spring plowing and preparation are under way across China. In the intelligent seedling cultivation center in Honglai Town, Quanzhou City, Fujian Province, seedlings are growing rapidly under the "care" of the intelligent system. With the help of intelligent facilities such as ventilation, temperature control and spraying, the seedling cultivation trays can receive light and sprinkler irrigation in turns. The fully mechanized seedling cultivation process saves time and effort in spring plowing and agricultural production.
