BED FOR NUTRICULTURE AND CULTIVATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a bed for nutriculture capable of appropriately adjusting water content and temperature in solid culture medium, and improving yield of plant.SOLUTION: Moisture vapor permeability of a cover sheet for housing a nutritious liquid holding body (solid culture medium) of bed for nutriculture is adjusted to 500 g/(m24 hours) or more, and a region having less than 90% of reflective index in a visible light region is formed in the sheet. The cover sheet may include a moisture-permeable waterproof sheet having 500 g/(m24 hours) or more of moisture vapor permeability and 1 kPa or more of waterproof pressure. The moisture-permeable waterproof sheet may include: a porous layer which includes polyethylene-based resin and has 0.1 to 15 μm of an average pore diameter and 10 to 100 μm of an average thickness; and a reinforcing layer which includes long-fiber nonwoven fabric and has 10 to 100 g/mof fabric weight.SELECTED DRAWING: None
