Abstract: The object of this invention is to provide a plant cultivation system to efficiently supply the elements necessary for plant growth to the plant cultivation materials, which provides a cultivation environment for accelerating plant growth by supplying the elements necessary for plant growth, a cultivation method using the system and a production method for the system. This invention provides a plant cultivation system comprising a plant cultivation material, which provides a cultivation environment for accelerating plant growth by supplying the elements necessary for plant growth, and a container storing a liquid such as water, a nutrition solution and agrochemical products or a liquid supply tank storing a liquid such as water, a nutrition solution and agrochemical products in combination with tubing.

Abstract: There are provided an organism-culture apparatus in which a pooled culture medium and a culturing tissue is not directly contacted, which comprises a culture medium, and a microporous body having the water-absorbing ability, a part of which is immersed in the culture medium, or an intervening body connected to the microporous body which can supply the culture medium to the microporous body by contact between a part of the intervening body and the culture medium, wherein the culture medium is transferred upwardly via communicating pores in the interior of the microporous body to supply the culture medium to an organism tissue or an organism cell placed on a surface of the microporous body, whereby, the organism tissue or the organism cell is cultured, as well as a method of culturing an organism using the same.

Abstract: An organism-culture apparatus, which can be conveniently prepared, can be stored for a long period, can be efficiently handled, and can be adapted to various organisms and culture conditions without restricting a kind of an organism to be cultured or the culture condition, and can be recycled after sterilization and washing is provides. The organism-culture apparatus, which comprises a microporous body retaining a culture medium, wherein an organism is cultured on a surface of the microporous body.

Abstract: Roots of a cultivated plant 30 is directly made contact with the surface of a cultivating apparatus 10 comprising microporous boxes 12, 13. It is, therefore, possible to obtain a cultivating apparatus capable of attaining effortless supply of nutrient/water, water conservation, easy miniaturization and indoor cultivation.
