BED OF PLANT CULTIVATION APPARATUS

摘要

PURPOSE: A bed for a plant cultivation apparatus is provided to use an overflow pipe block capable of increasing the nutrient solution level in a bed flow path for smoothly supplying a nutrient solution to seedlings. CONSTITUTION: A bed(10) for a plant cultivation apparatus includes the following: a flow path(11) of a nutrient solution from a water inlet end to a water outlet end(15); an overflow pipe block(30) for increasing the nutrient solution level around the water outlet end in the flow path; a small passage(33) in the overflow pipe block for flowing the nutrient solution on a ground plane(31) on the bottom of the flow path, for preventing the nutrient solution stagnation; and conversion columns(35) located on both sides of the overflow pipe block.
