Abstract
In order to reduce the irrigation run-off and contamination of the
underground water, effects of different nutrient levels were investigated in
Spathiphyllum“Sensation” grown in an ebb and flow system, and comparison on
the growth with hand-watering was also determined. Plants grew equally well
from a range of 1/4 to full-strength of Johnson’s solution in the ebb and flow
system, indicating the possible luxury consumption of plants was grown in the
full-strength treatment, moreover, full-strength treatment produced more necrotic
leaves and reduced the root growth. These results indicated that a range of 1/4 to
half strength of Johnson’s solution was optimum for the growth of Spathiphyllum
“Sensation” in the ebb and flow system. From September, 1997 to April, 1998,
there were no difference in the plant growth between irrigation methods at the
same irrigation frequency, however plants grown in the ebb and flow system had
the fewest number of chlorotic and puckered leaf. From May 1998 to January,
1999, plants growth in the ebb and flow system was better than that of the hand
watering treatment. In additions, the ebb and flow system could save water and
nitrogen uses by 33% and increased the water use efficiency by 40%.
