It is preferable to use a system that can adjust the level. FIG. 1 is a side view showing a cross section of an example of implementation of the hydroponic system in the hydroponic method for plants of the present invention. Bottom surface A non-woven fabric 15 is spread on a cultivation bed culture medium tank 2 provided with a mesh board 1 to prevent the roots of the plants from passing through the mesh board!, and the cultivated plants 4 are filled with a fired product of diatomaceous earth as the cultivation bed medium material B3. The cultivation bed medium tank 2 is placed in an M1 nutrient solution tank 6 supported by the bed support 5, and the plant nutrient solution 10 is fed from the nutrient solution storage tank 7 through a supply pipe 8 to the plant nutrient solution. The plant nutrient solution is supplied to the tank 6 and discharged through the discharge pipe 11, and the level of the plant nutrient solution in the plant nutrient solution tank 6 is determined by the height of the discharge pipe. It enters the cultivation bed medium tank 2 through the mesh 1, rises throughout the cultivation bed medium material 3 by capillary action in the pores of the cultivation bed medium material 83, and is absorbed by the roots of the cultivated plants 4. However, there is air between the particles of the cultivation bed medium material B3, and the acid purple is sufficiently supplied to the roots of the cultivated plants 4. The level of the plant nutrient solution in the plant nutrient solution tank 6 is controlled by the discharge pipe 11.
It can be raised by closing the pulp 14, but it can return to its original state by opening the pulp 14. Moreover, the plant nutrient solution 1O supplied from the nutrient solution storage tank 7 through the pulp 9 of the supply pipe 8 can also be supplied from the water sprinkling nozzle 13 located above the cultivation bed medium tank 2. Plant cultivation of the present invention [11] Porous ceramics are used as the cultivation bed medium material of the cultivation bed medium tank in the cultivation method. Porous ceramics allow the plant nutrient solution to rise to the roots of cultivated plants due to capillary action in the pores, and supply the plant nutrient solution to the roots of the plants. A fired product of diatomaceous earth can be used as the porous ceramic. The fired product of diatomaceous earth is prepared by granulating diatomaceous earth to prepare granular diatomaceous earth with a particle size of 0 to 51, and then heating the granular diatomaceous earth to a temperature of 800°C or higher, preferably 1000°C or higher for 0.5 to 3 hours. Obtained by time burning stones. The life grains of diatomaceous earth can be produced by an extrusion method, a rolling convex grain method, or a pressing method, and a binder such as clay, lignin, or polyvinyl alcohol can be added to the a grains. The fired product of diatomaceous earth is a porous particle with many fine pores, has a large water retention capacity, and has a low level of plant nutrient solution Cw.
Even if surface R) is below the cultivation bed medium tank, the plant nutrient solution rises due to the capillary action of the minute pores in the fired diatomaceous earth, and the diatomaceous earth above the level of the plant nutrient solution (surface 8) A plant nutrient solution can be retained in the fired product. An example of a fired product of diatoms is soft ceramics commercially available from Isolite Kogyo Co., Ltd. under the trade name Isolite CC.
