This invention relates to plant cultivation materials and plant cultivation methods using the materials.
To date, a large number of plant cultivation methods to accelerate the plant growth such as the methods utilizing superabsorbent polymers represented by crosslinked sodium polyacrylate gels (Patent Literature 1), foamable resins represented by polyvinyl alcohols, polyurethanes and polystyrenes (Patent Literature 2), and breathable films and porous films represented by non-woven fabrics, or multi films (Patent Literature 3 and Patent Literature 4) have been reported.
But the cases that the amount of water or a nutrient solution required depending on the plant growth cannot be supplied have been observed in the cultivation method utilizing superabsorbent polymers, the cases that the air necessary for the plant growth cannot be sufficiently supplied have been observed in the cultivation method utilizing formable resins, and the cases that the amount of water or a nutrient solution necessary for the plant growth cannot be retained and therefore stably supplied to plants have been observed in the cultivation method utilizing breathable films or porous films.
A cultivation method utilizing ceramics (Patent Literature 5) was discovered in order to solve the aforementioned problems. But the capability of this method to supply to plants the amount of water or a nutrient solution necessary for the plant growth has been still insufficient, and thus, no plant cultivation environment for plants to absorb the amounts of the elements necessary for the plant growth as much as plants want whenever plants want has not been provided yet.
The challenge to be solved by this invention is to provide plant cultivation materials suitable to make a plant cultivation environment in which plants can absorb the amount of the elements necessary for the plant growth as much as plants want whenever plants want in order to accelerate the plant growth and a plant cultivation methods using these materials.
As a result of intensive studies to solve the aforementioned challenge, the inventors have discovered that the materials having the liquid retentivity and the liquid transitivity, and comprising a structure capable to provide the environment suitable for the plant respiration for the plant growth can accelerate the plant growth, since plants can absorb, from the materials, the amount of the elements necessary for the plant growth as much as plant want whenever plants want.
This invention to solve the aforementioned challenge is as follows:
(1) A plant cultivation material, 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.
(2) A plant cultivation material, which has the liquid retentivity and the liquid transitivity, 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.

(4) A plant cultivation material, which is capable to retain water a nutrient solution and/or the liquid dissolving agrochemical products, which has the cavities for the smooth transitivity of Liquid, which comprises the layered structure capable to control the root growth, 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.
(5) A plant cultivation material, which is capable to retain water, a nutrient solution and/or the liquid dissolving agrochemical products, which has the cavities for the smooth transitivity of Liquid, which comprises the layered structure capable to control the root growth so that roots can respire sufficient air, from which plants can absorb the amounts 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.
(6) A plant cultivation method using the plant cultivation materials according to any one of (1) to (5).
The plant growth is made accelerated, the crop yield and the quality are made higher, and the supply of the elements necessary for the plant growth can be controlled to the minimum required, since plants can absorb the amounts of the elements necessary for the plant growth as much as plants want whenever plants want by utilizing the plant cultivation materials and the plant cultivation methods using the materials of this invention.

The elements necessary for the plant growth can be supplied to Materials put in the containers by several methods such as the method of transferring the elements filled in the containers to Materials, the method of using the elements previously filled in Materials and the method by the parallel use of these methods.
For example, Elements can be supplied to the plants by Liquid penetrable in Materials being filled in the container, by Materials being contacted with Liquid, and by Liquid being penetrated in Materials. Liquid is available to be replenished the containers with when required, and able to be replenished the container with continuously or at intervals.

Synthetic pulp (manufactured by Mitsui Chemicals, Inc.; SWP (Registered Trademark): E400) was prepared into a cube with a size of 100 mm×100 mm×100 mm (in height), and the cube was then floated on the liquid surface of a nutrient solution (the composition is shown in Table 18) poured into a cultivation case. After a hole with a size of 20 mm×20 mm×10 mm (in depth) was made on the upper surface of the synthetic pulp, a broad bean seed was put in the hole (seeding on May 31, 2012). Twenty two days after the seeding, when the plant grew up to approximately 200 mm in height, Aphis craccivora was released to the plant. Seven days after the insect release, an aqueous solution dissolved with 10 mg of dinotefuran (manufactured by MITSUI CHEMICALS AGRO, INC.; an insecticide classified in neonicotinoids) in 1,000 mL of the nutrient solution was prepared, and the solution was then inserted to the synthetic pulp by a syringe.

Grotop Master (a good based on rockwools) manufactured by CRODAN was prepared into a cuboid with a size of 80 mm×100 mm×75 mm (in height), the Grotop Master was then immersed in a nutrient solution (the composition is shown in Table 2) poured into a cultivation case, and wheat seeds were put on the upper surface of the Grotop Master in order to observe the growth and to measure the amount of the nutrient solution consumed during the growth (seeding on Dec. 20, 2011). The results of the growth and the amount of the nutrient solution consumption are shown in Table 36 in contrast to the results of Example 2.
A ceramic manufactured by Phytoculture Control Co., Ltd. was immersed in a nutrient solution (the composition is shown in Table 4) poured into a cultivation case, and grape tomato seeds were put on the surface of the ceramic in order to measure the sugar content of the fruitive grape tomato pulp by a hand-held refractometer IATC-1E (Brix: 0% to 32%) manufactured by luchi Seieido Co., Ltd. The result or the sugar content is shown in Table 37 in contrast to the results of Example 3.
Synthetic pulp (manufactured by Mitsui Chemicals, Inc.; SWP (Registered Trademark): E400) was prepared into a cube with a size of 100 mm×100 mm×100 mm (in height), and the cube was then floated on the liquid surface of a nutrient solution (the composition is shown in Table 18) poured into a cultivation case. After a hole with a size of 20 mm×20 mm×10 mm (in depth) was made on the upper surface of the synthetic pulp, a broad bean seed was then put in the hole (seeding on May 31, 2012). Twenty two days after the seeding, when the plant grew up to approximately 200 mm in height, Aphis craccivora was released to the plant in order to observe the transition of the number of surviving Aphis craccivora. The result was shown in Table 38 in contrast to the results of Examples 25 and 26.
