Advantages of Tidal Seedbed Tidal Seedbed Cultivation Bed is a kind of cultivation bed with plastic structure on the bed surface. Its bed surface is made of tidal seedling tray made of plastic, which is also called bottom irrigation cultivation bed. The tidal seedbed adopts the same upright posts and supports as the commercial metal structure cultivation bed, and the bed surface adopts impermeable plastic seedling trays formed by molding. During irrigation, the seedling tray is filled with clear water or nutrient solution and kept for a certain period of time, so that crops can absorb water through the drainage holes at the bottom of the flowerpot by capillary action. After that, the irrigation water is discharged from the cultivation bed, collected and reused, or directly discharged to the local sewer. Tidal seedbed is a kind of irrigation method with bottom water supply designed for potted plant nutrient solution cultivation or container seedling cultivation and soilless culture. This method uses the drop principle to realize regular water supply and fertilization. A large number of experimental studies at home and abroad show that the growth of crops under tidal irrigation is obviously better than that under artificial irrigation, which can not only reduce the occurrence of gangrene and wrinkled leaves.
