- 要約等A reliable and effective water and nutrient delivery system with porous tubes has been developed for growing plants at a controllable, constant, negative water pressure. Multiple porous stainless steel tubes were positioned 4cm apart in a shallow tray (44cm long, 32cm wide and 8cm deep), and then covered with a 4cm layer of fine medium (≤1mm in diameter). Nutrient solution was recirculated through the porous tubes under a negative pressure maintained with a siphoning procedure. A range of negative pressures from 0 to 2.0 kPa in the rooting matrix were obtained by changing the length and diameter of inlet and outlet tubing, and/...
