[Prior art]
Hydroponic cultivation is cleaner and easier to work than soil cultivation, there are no continuous cropping obstacles, the same pattern can always be expected, and cultivation can be automated regardless of soil quality or management. This is a popular cultivation method centering on leafy vegetables. However, the conventional cultivation method is a cultivation method in which the root area of multiple plants is shared in a continuous medium. It was.
[0003]
For this reason, in the management work after the end of cultivation, since the roots of a plurality of plant bodies are intertwined in a mat shape around the solid medium, it becomes difficult to separate the roots from the solid medium and carry out the plant bodies, It takes a lot of labor to transport the medium, and when a large amount of medium is used, disposal is cumbersome and the processing cost is high. Since the medium contained a large amount of water in the liquid, there was a drawback that it was difficult to manage the liquid supply amount.
[0004]
On the other hand, as a cultivation method using a cultivation container (pot) to prevent root entanglement of adjacent plants, for example, a slit is formed at the bottom of the cultivation container, and a water absorbent mat is formed inside the bottom. A method of cultivating a plant by laying and laying a root-proof sheet on the upper surface of the water-absorbent mat and allowing the nutrient solution to penetrate the medium through the water-absorbent mat and the root-proof sheet (Japanese Patent Laid-Open No. 8-154509) , Forming a water passage hole at the bottom of the cultivation container, providing a porous film having a hole smaller than the root crown of the root of the plant under the bottom, and supplying nutrient solution to the water level at which the porous film wets A method for cultivating a plant body (Japanese Patent Laid-Open No. 3-22926) is known.
[0005]
However, as in the former cultivation method, the supply per hour is not sufficient for supplying the nutrient solution into the medium through the water-absorbent mat or root-proof sheet, or in the supply such that the nutrient solution is moistened as in the latter cultivation method. The amount of liquid is limited to a small amount, especially in the summer when the amount of transpiration is high, depending on the type and size of the plant, it may cause wilt. Since the bottom of the cultivation container has a slit and a water passage hole, it is not easy and reliable to clean and disinfect the cultivation container after completion of cultivation, and there is a risk of disease occurrence in the next cultivation due to insufficient washing there were.
