PURPOSE:To obtain the title device capable of uniformly supply a nutritive solution to plants and reducing the frequency of supplying the nutritive solution, by successively laying a water retention sheet and a root preventing sheet on the top of a slant bed equipped with a nutritive solution feeding member at the upper part and a drain channel at the lower part. CONSTITUTION:A water retention sheet 11 is laid on the top of a slant bed 6, then a root preventing sheet 12 is spread over the sheet 11, a nutritive solution feeding member 8 is arranged on the slope of the slant bed 6, and a drain channel 7 is set under the slant bed. Consequently, a nutritive solution sent from the nutritive solution feeding member 8 is retained in the water retention sheet 11, uniformly supplied to plants by capillary action of the sheet 11, and the nutritive solution more than water retention ability is dripped to the drain channel 7. |
