PROBLEM TO BE SOLVED: To solve the problem that the conventional plant culture apparatus, particularly a horticulture, is in a state in which a soil layer 13 is always wet caused by a condition in which roots and stems of plants are submerged under water, or by scattering of water drops, therefore the condition causes for root rot by generating the condition in which the degree of water rot is high, the soil layer is easily oxidized and has bad aeration, so the roots can not breathe, therefore the culture apparatus is limited to plants strong to water or preferring water, and is a culture apparatus for limited plants.SOLUTION: Various species of plants are brought to be able to grow by improving the growth environment of the plants in a soil layer 13 by installing a water layer 4, an air/water layer 7, an air layer 9 and the soil layer 13, vaporizing elements required of the plants from a liquid (water) to a water-containing air (moist air) through the function of each layer, particularly the air layer 9, guiding the air from the inside of the air layer 9 having generated the state of pressure elevation to a vent plate 11 placed on the bottom surface of the soil layer 13, supplying the elements required of the plants by permeation, vaporizing and scattering them into the soil layer 13 and transpiring on the surface of the soil layer 13. |
