Description

本発明の実施の形態の水耕栽培用の培地は、植物の地下部を囲む部分であり、多孔性材料、繊維材料、または高吸水性高分子によって構成され、浸透した水分を保持する浸透性部と、前記浸透性部を囲むように設けられ、前記水分が浸透しない非浸透性部とを備えている。 The culture medium for hydroponics according to the embodiment of the present invention is a part surrounding the underground part of the plant, and is composed of a porous material, a fiber material, or a superabsorbent polymer, and has permeability that retains permeated moisture. And a non-permeable portion that is provided so as to surround the permeable portion and does not penetrate the moisture .

本実施の形態の水耕栽培用の培地３０は、浸透性部２が土、砂、または石等のような、自然界では、藻、カビ、または病害虫等が栄養素とする有機物が付着した材料を含んでいない。本実施の形態においては、浸透性部２は、通常、藻、カビ、または病害虫等が栄養素とする有機物が付着していないスポンジによって構成されている。そのため、土、砂、または石等のような、自然界では、藻、カビ、または病害虫等が栄養素とする有機物が付着した材料が植物１の水耕栽培用の培地として用いられる場合に比較して、藻、カビ、または病害虫等の発生確率が低減されている。非浸透性部３も、同様の理由から、藻、カビ、または病害虫等が栄養素とする有機物が付着していないことが好ましい。そのため、本実施の形態においては、非浸透性部３は、通常、藻、カビ、または病害虫等が栄養素とする有機物が付着していないゴム等の弾性体によって構成されている。 The culture medium 30 for hydroponic cultivation of the present embodiment is made of a material in which the osmotic part 2 is attached with organic substances that are nutrients such as algae, fungi, or pests in nature, such as soil, sand, or stone. Does not include. In the present embodiment, the osmotic part 2 is usually constituted by a sponge to which organic substances that are nutrients such as algae, fungi, or pests are not attached . Therefore , in the natural world, such as soil, sand, or stone, compared to the case where a material to which organic matter that is a nutrient of algae, mold, pests, etc. is used as a culture medium for hydroponics of the plant 1 is used. The occurrence probability of algae, fungi, pests, etc. is reduced. For the same reason, it is preferable that the non-permeable portion 3 is not attached with organic substances that are nutrients such as algae, molds, or pests . For this reason, in the present embodiment, the non-permeable part 3 is usually constituted by an elastic body such as rubber to which organic substances that are nutrients such as algae, molds, pests and the like are not attached .

以上から分かるように、本実施の形態においては、浸透性部２および非浸透性部３のいずれもが、通常、藻、カビ、または病害虫等が栄養素とする有機物が付着していない材料により構成されている。つまり、水耕栽培用の培地３０の全体が、通常、藻、カビ、または病害虫等が栄養素とする有機物が付着していない材料のみにより構成されている。このような水耕栽培用の培地３０によれば、植物１の地下部１Ａの周囲の適切な範囲のみを良好な湿潤状態に維持しながら、藻、カビ、または病害虫などの発生を防止することができる。 As can be seen from the above, in the present embodiment, both of the permeable portion 2 and the non-permeable portion 3 are usually composed of a material to which organic substances that are nutrients such as algae, molds, or pests are not attached. Has been. That is, the whole culture medium 30 for hydroponics is normally comprised only of the material to which the organic substance which nutrients, such as algae, a mold | fungi, or a pest , do not adhere . According to such a culture medium 30 for hydroponics, the generation of algae, fungi, pests and the like is prevented while maintaining only an appropriate range around the underground portion 1A of the plant 1 in a good wet state. Can do.

また、剛性部４は、水分が浸透しない材料で構成されている。したがって、余分な水分が剛性部４に保持されることに起因して、藻、カビ、または病害虫等が発生することが防止されている。また、剛性部４は、藻、カビ、または病害虫等の発生確率を低減する観点から、藻、カビ、または病害虫等が栄養素とする有機物が付着していないことが好ましい。本実施の形態においては、浸透性部２、非浸透性部３、および剛性部のいずれもが、通常、藻、カビ、または病害虫等が栄養素とする有機物が付着していない材料により構成されている。つまり、水耕栽培用の培地３０の全体が、通常、藻、カビ、または病害虫等が栄養素とする有機物が付着していない材料のみにより構成されている。 The rigid portion 4 is made of a material that does not allow moisture to penetrate. Therefore, the generation of algae, fungi, pests and the like due to the extra water being held in the rigid portion 4 is prevented. Moreover, it is preferable that the organic substance which an algae, a mold | fungi, a pest, etc. use as a nutrient is not adhering to the rigid part 4 from a viewpoint of reducing the generation | occurrence | production probability of algae, a mold, a pest, etc. In the present embodiment, all of the permeable portion 2, the non-permeable portion 3, and the rigid portion are usually made of a material to which organic substances that are nutrients such as algae, molds, or pests are not attached. Yes. That is, the whole culture medium 30 for hydroponics is normally comprised only of the material to which the organic substance which nutrients, such as algae, a mold | fungi, or a pest , do not adhere .

上記実施の形態３〜５においては、実施の形態１および２において説明された水耕栽培用の培地３０および４０のそれぞれが使用され得る水耕栽培装置７０、８０、および９０を説明した。水耕栽培装置７０、８０、および９０の構成も、水耕栽培用の培地３０および４０と同様に、カビ、藻、または病害虫等の植物栽培上の弊害の発生の防止の観点から、藻、カビ、または病害虫等が栄養素とする有機物が付着していないことが好ましい。つまり、水耕栽培装置７０、８０、および９０の全体が、通常、藻、カビ、または病害虫等が栄養素とする有機物が付着していない材料により構成されていることが好ましい。 In the said Embodiment 3-5, the hydroponic cultivation apparatuses 70, 80, and 90 which can use each of the culture medium 30 and 40 for hydroponic cultivation demonstrated in Embodiment 1 and 2 were demonstrated. From the viewpoint of preventing the occurrence of harmful effects on plant cultivation such as fungi, algae, or pests, the constitution of the hydroponic cultivation apparatuses 70, 80, and 90 is the same as the culture mediums 30 and 40 for hydroponic cultivation . It is preferable that organic substances that are nutrients by molds, pests, and the like are not attached . That is, it is preferable that the whole of the hydroponic cultivation apparatuses 70, 80, and 90 is generally composed of a material to which organic substances that are nutrients such as algae, fungi, or pests are not attached .
