| 摘要 |
The invention concerns a pot (1) or a container of another shape suitable for the cultivation of a horti-floricultural species grown with the "soilless" technique, provided with an external jacket-shaped air-gap (2) for the forced circulation of a thermal carrier fluid for the thermal conditioning of the substrate and of the roots apparatus contained therein. The jacket-shaped air-gap (2) is provided with two passage holes with a sleeve insert (5) for the inlet and the outlet of the thermal carrier fluid and with a flow deflection baffle (7) in front of each one of the two inlet and outlet holes. The pot (1) also comprises preferably two longitudinal baffle (10) dividing the jacket-shaped air-gap (2) in two sectors, and two or more longitudinal stiffening grooves (11) around the internal wall (3). The device is capable of maintaining the substrate and the roots apparatus of a "soilless" culture within optimal temperature ranges, while maintaining a localized microclimate around the plant and allowing to limit the temperature of the whole greenhouse internal volume, thereby resulting in an energy saving. |
