Abstract

Plant cultivation materials, which have the liquid retentivity and the liquid transitivity, which provide the best environment for plants respiration, which comprises polyesters, natural pulps and/or synthetic pulps such as polyolefin pulps, from which plants can absorb the amount of the elements necessary for the plant growth as much as plants want whenever plants want, and which provide the cultivation environment to accelerate the plant growth, and the plant cultivation methods by using the materials can be provided.

First claim

The invention claimed is:

1. A plant cultivation material, which comprises a material capable of allowing plant roots to grow so that the roots can respire sufficient air, from which the plant can absorb the amount of the elements necessary for the plant growth as much as the plant wants whenever the plant wants, and which provides a cultivation environment to accelerate the plant growth and which comprises a layered structure capable to control the root growth so that roots can respire sufficient air, from which plants can absorb the amount of the elements necessary for the plant growth as much as plants want whenever plants want, and which provides the cultivation environment to accelerate the plant growth, wherein the layered structure comprises a planar structure formed by intertwining materials constituting the cultivation material for growth of the roots not only in the layer thickness direction, but also in a direction perpendicular to the layer thickness direction along to the planar structure.

2. A plant cultivation material according to claim 1 , wherein the layered structure comprises a three-dimensional structure formed by laminating a planar structure on the other planar structure in a layer thickness direction, wherein, the planar structures are formed by continuously or discontinuously intertwining the materials constituting the cultivation material in a two-dimensional manner.

3. A plant cultivation material according to claim 2 , wherein the thickness of the planar structure is 0.01 mm or more.

4. A plant cultivation material, which has liquid retentivity and liquid transitivity, which comprises a material capable of allowing plant roots to crow so that the roots can respire sufficient air, from which the plant can absorb an amount of the elements necessary for plant growth as much as the plant wants whenever the plant wants, and which provides a cultivation environment to accelerate plant growth and which comprises a layered structure capable to control the root growth so that roots can respire sufficient air, from which plants can absorb the amount of the elements necessary for the plant growth as much as plants want whenever plants want, and which provides a cultivation environment to accelerate the plant growth, wherein the layered structure comprises a planar structure formed by intertwining materials constituting the cultivation material for growth of the roots not only in the layer thickness direction, but also in a direction perpendicular to the layer thickness direction along to the planar structure.

5. A plant cultivation material according to claim 4 , wherein the layered structure comprises a three-dimensional structure formed by laminating a planar structure on the other planar structure in a layer thickness direction, wherein, the planar structures are formed by continuously or discontinuously intertwining the materials constituting the cultivation material in a two-dimensional manner.

6. A plant cultivation material according to claim 5 , wherein the thickness of the planar structure is 0.01 mm or more.

7. A plant cultivation material, which is capable of retaining liquid such as water, a nutrient solution and agrochemical products, which has cavities for smooth transitivity of the liquid, which comprises a layered structure capable of allowing plant roots to grow so that the roots can respire sufficient air, from which the plant can absorb the amount of the elements necessary for plant growth as much as the plant wants whenever the plant wants, and which provides a cultivation environment to accelerate plant growth and which comprises a layered structure capable to control the root growth so that roots can respire sufficient air, from which plants can absorb the amount of the elements necessary for the plant growth as much as plants want whenever plants want, and which provides the cultivation environment to accelerate the plant growth, wherein the layered structure comprises a planar structure formed by intertwining materials constituting the cultivation material for growth of the roots not only in the layer thickness direction, but also in a direction perpendicular to the layer thickness direction along to the planar structure.

8. A plant cultivation material according to claim 7 , wherein the layered structure comprises a three-dimensional structure formed by laminating a planar structure on the other planar structure in a layer thickness direction, wherein, the planar structures are formed by continuously or discontinuously intertwining the materials constituting the cultivation material in a two-dimensional manner.

9. A plant cultivation material according to claim 8 , wherein the thickness of the planar structure is 0.01 mm or more.

10. A plant cultivation method using the plant cultivation material according to claim 1 .

11. A plant cultivation method using the plant cultivation material according to claim 2 .

12. A plant cultivation method using the plant cultivation material according to claim 3 .

13. A plant cultivation method using the plant cultivation material according to claim 4 .

14. A plant cultivation method using the plant cultivation material according to claim 5 .

15. A plant cultivation method using the plant cultivation material according to claim 6 .

16. A plant cultivation method using the plant cultivation material according to claim 7 .

17. A plant cultivation method using the plant cultivation material according to claim 8 .

18. A plant cultivation method using the plant cultivation material according to claim 9 .
