Seedling raising factory is an important technology in modern agriculture. It uses modern agricultural equipment for intensive seedling raising production, integrating machinery, electricity, standardization, and self-control. It is a technology that combines modern agricultural engineering and agronomy. The seedling raising factory mainly includes a seedling raising and sowing workshop and a seedling raising and sowing workshop (greenhouse greening room). The seedling raising and sowing workshop includes a seed soaking pool, a chest breaking germination chamber, and is equipped with a seedling raising and sowing joint operation machine to complete the procedures of rice seed soaking, disinfection, and seedling raising and sowing. The seedling cultivation workshop is a large independent (or connected) plastic greenhouse that uses natural light and temperature conditions for insulation, moisture retention, and seedling greening.
