PURPOSE:To obtain the titled apparatus, provided with a culture vessel having a netlike bottom on a nutrient solution tank and a spray device for sucking up a nutrient solution in the nutrient solution tank by utilizing compressed air and spraying the solution on the bottom of the culture vessel and capable of always supplying nutrients and oxygen to the whole roots of cultivated plants. CONSTITUTION:The aimed apparatus is constituted so as to initially provide a culture vessel 11 having a netlike bottom on a nutrient solution tank 12 and further contain a spraying device 13 for sucking a nutrient solution in the nutrient solution tank 12 by utilizing compressed air and spraying the solution on the bottom of the culture vessel 11. Furthermore, the spraying device 13 is constituted so as to, e.g. send the compressed air to a nozzle part 16, provide a negative pressure in the interior of the nozzle part and suck the nutrient solution from a pipe 15 to spray the solution from the nozzle part 16. |
