Abstract
Official abstract text for this publication.
There is provided a medium for plant cultivation comprising an ethylene-vinyl alcohol copolymer chip. An ethylene content of ethylene-vinyl alcohol copolymer included in the ethylene-vinyl alcohol copolymer chip is preferably 20 to 60 mol %. In addition, a water content in the ethylene-vinyl alcohol copolymer chip is preferably 20 to 300 parts by mass relative to 100 parts by mass of the ethylene-vinyl alcohol copolymer. As a result, it is possible to provide a medium for plant cultivation, which is capable of being used instead of the soil or rock wools, and with which it is possible to sufficiently grow crop plants, to have excellent recyclability, to facilitate a process for disposal the medium, and to have a small environmental burden.
First claim
Opening claim text (preview).
The invention claimed is: 1. A medium comprising an ethylene-vinyl alcohol copolymer chip, wherein the ethylene-vinyl alcohol copolymer chip comprises ethylene-vinyl alcohol copolymer and water, and a water content is from 20 to 300 parts by mass relative to 100 parts by mass of the ethylene-vinyl alcohol copolymer. 2. The medium according to claim 1 , wherein an ethylene content of ethylene-vinyl alcohol copolymer in the ethylene-vinyl alcohol copolymer chip is from 20 to 60 mol %. 3. The medium according to claim 1 , wherein a melt flow rate of the ethylene-vinyl alcohol copolymer in the ethylene-vinyl alcohol copolymer chip is from 0.1 to 100 g/10 minutes. 4. The medium according to claim 1 , wherein the ethylene-vinyl alcohol copolymer chip comprises ethylene-vinyl alcohol copolymer and water, and a water content is from 30 to 300 parts by mass relative to 100 parts by mass of the ethylene-vinyl alcohol copolymer. 5. The medium according to claim 1 , wherein a maximum length of the ethylene vinyl alcohol copolymer chip is from 1 to 50 mm. 6. The medium according to claim 1 , wherein a shape of the ethylene-vinyl alcohol copolymer chip is approximately a globular shape, approximately a disc shape, approximately a cylinder shape, or a flake shape. 7. The medium according to claim 1 , wherein a content of the ethylene-vinyl alcohol copolymer chip is 50% by mass or more.
