Studies on the Spray-culture by the Fog-box : II. Different effects of fog-culture and water-culture on the growth of several crops

[摘要] 1) The present study was carried out in order to determine the differential effects of fog-culture (spray-culture) and water-culture on the growth of crops. The following crops were used in this experiment: wheat, tobacco, oats, broad bean, barley, Italian ryegrass, tomato, rice and sweet potato. 2) The growth of roots of all the crops was significantly more rapid in fog-culture than in water-culture. 3) The favorable effect of fog-culture on top growth was not clearly seen as in the case of root growth, but it was excellent in wheat, tomato and sweet potato. 4) The dry matter increment (g / plant / day) of tobacco, broad bean, tomato and sweet potato was significantly more in fog-culture than in water-culture. 5) The dry matter increment of root (g / plant / day) in fog-culture was significantly more than in water-culture, with wheat, oats broad bean, Italian ryegrass, tomato and sweet potato. 6) The top-root ratio of the plants grown in fog-culture was lower in comparison with those grown in water-culture in all the experimental crops with the exception of tobacco. 7) In general, the growth of wheat, tobacco, broad bean, tomato, sweet potato was more excellent in fog-culture than in water-culture, but the difference was not clear in rice.
