<P>PROBLEM TO BE SOLVED: To provide an elevated cultivation device changing and automatically controlling the level of water stored in a water storage sheet, and stabilizing maintenance of the level of water stored in the water storage sheet so as to improve the yield of products to be cultivated. <P>SOLUTION: This elevated cultivation device includes a permeable culture medium holding sheet 10 which has a cross section formed in a U shape, and holds a culture medium M where a product 1 to be cultivated is planted, a nonpermeable water storage sheet 20 which has a cross section formed in a U shape, and holds the lower side of the culture medium holding sheet 10 to store water W, a support body 40 which supports the culture medium holding sheet 10 and the water storage sheet 20 on a place the ground, and a water supplying means 50 which automatically supplies water W to the water storage sheet 20 when the level of water W stored in the water storage sheet 20 becomes a minimum level L, and automatically stops supplying water W to the water storage sheet 20 when the level of water W stored in the water storage sheet 20 becomes a maximum level H. The water W stored in the water storage sheet 20 is infiltrated into the culture medium M through the culture medium holding sheet 10 so as to let a root part 1a of the product 1 to be cultivated absorb. <P>COPYRIGHT: (C)2011,JPO&INPIT |
