METALLIC POROUS BODY CULTIVATION MEDIUM AND CULTIVATION CONTAINER

To provide a metallic porous body cultivation medium and a cultivation container which are repeatedly usable and suitable for raising plants.SOLUTION: A metallic porous body cultivation medium 10 consists of a spongy metallic porous body 11 having an average pore diameter of 0.5 mm or more and 2 mm or less and a porosity of 65% or more and 98% or less. It is preferable that a top face of the spongy metallic porous body has recess parts for holding seeds, and it is preferable that the recess parts have a fall prevention part under the recess parts. It is preferable that the spongy metallic porous body is any one of titanium, titanium alloy and cobalt chromium alloy, and is subjected to alkali treatment on its surface. It is preferable that a side face of a cultivation container housing the metallic porous body cultivation medium is transparent such that the metallic porous body cultivation medium can be seen. It is preferable that a side face of the cultivation container has a cutout part for taking out the metallic porous body cultivation medium.SELECTED DRAWING: Figure 1 【課題】繰り返し利用可能で植物の育成にも適した金属多孔体栽培培地及び栽培容器を提供する。【解決手段】金属多孔体栽培培地１０は、平均孔径が０．５ｍｍ以上２ｍｍ以下で、空孔率が６５％以上９８％以下のスポンジ状金属多孔体１１からなる。スポンジ状金属多孔体の上面に種子を保持するための凹部を有することが好ましく、凹部の下部に落下防止部を有することが好ましい。スポンジ状金属多孔体がチタン、チタン合金及びコバルトクロム合金のいずれか１つであって、表面にアルカリ処理がなされていることが好ましい。金属多孔体栽培培地が見えるように、金属多孔体栽培培地を収容した栽培容器の側面が透明であることが好ましい。栽培容器の側面に金属多孔体栽培培地を取り出すための切り欠き部を有することが好ましい。【選択図】図１
