Title:
METHOD FOR NUTRICULTURE OF LIQUID SUPPLY CONTROL
Document Type and Number:
Japanese Patent JP2004008067
Kind Code:
A
Abstract:
To provide a method for nutriculture of liquid supply control, with which a liquid supply is controlled based on the amount of solar radiation.
A medium having ≥150 liters/m3 readily effective water content, ≥50 liters/m3 hardly effective water content, ≥20 cmols/kg cation exchange capacity and high physical/chemical buffer power is used as the medium. The liquid supply amount of a culture liquid per plant individual is adjusted to an amount to be supplied to 1 MJ/m2 integral solar radiation, the waste liquid ratio of the culture liquid discharged to the outside of a culture system is adjusted to ≤15% of the liquid supply amount and the liquid supply is controlled to extremely efficiently and excellently cultivate a plant.
