Method and apparatus for supplementing the feed solution of hydrocultures with desalinated water |
摘要 |
A hydroculture has a feed solution tank 11 from which feed solution is supplied to the plant roots by capillary action or pump action. Feed tubes 12 of a hydrophobic microporous material which is water vapor permeable but not water permeable are laid in this feed solution tank 11, and salt water having a substantially elevated temperature relative to the feed solution is led through the feed tube 12. In this way the used-up feed solution is replaced by desalinated water.
