摘要： PROBLEM TO BE SOLVED: To provide a method for hydroponic culture capable of preparing a medium suitable for growth, carrying out a simpler hydroponic solution control and suppressing an influence on a circumferential environment as much as possible in a hydroponic culture method of type for supplying a culture solution and culturing a plant and to obtain the medium useful for the method. SOLUTION: This method for hydroponic culture comprises carrying out hydroponic culture by using a medium having a readily effective water content (water content retained at -3 kPa to -1,600 kPa) adjusted to >=150 liter/m3 and a hardly effective water content (water content retained at -100 kPa to -1,600 kPa) adjusted to >=50 liter/m3 so that a simpler culture solution control is possible to perform and the influence on a circumferential environment can be suppressed as much as possible.

摘要： PROBLEM TO BE SOLVED: To provide a method for nutriculture of liquid supply control, with which a liquid supply is controlled based on the amount of solar radiation. SOLUTION: A medium having ≥150 liters/m 3 readily effective water content, ≥50 liters/m 3 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/m 2 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.

摘要： PROBLEM TO BE SOLVED: To provide a style hydroponics method of culturing by culture solution- supplying, which enables the preparation of a culture medium suitable for growth, the simple maintenance of the culture solution and the minimization of effects to ambient environments, and to provide the culture medium used therefor. SOLUTION: This land-improving method comprises using a hydroponics culture medium adjusted to an easily available water content (water content held at -3 to -1,600 kPa) of ≥150 l/m 3 and a hardly available water content (water content held at -100 to -1,600 kPa) of ≥50 l/m 3 . Thereby, the culture solution can simply be maintained, and effects to the ambient environments can minimized. COPYRIGHT: (C)2004,JPO
