Studies on the Spray-Cultred by the Fog-Box : 1. On the stucture and function of the box-box.

[摘要] In this report, the structure and function of fog-box, designe dby the authors for spray-culture, were described. This apparatus consisted of three parts, compressor, atomizer and fog-box. The fog was produced by atomizer working on the scent scent-shray spray principle, and atomizer and box were made of vinyl chloride in order to be protected from the corrosion by nutrient solution. After stopping of spray, therelative atomospheric humidities in the box were made saturated for 18, 10 and 2 minutes and the temperatures in the box were adjested to 15°, 20° and 30°C respectively. In this apparatus, wheat, beet, tomato, Italian-ryegrass and sweet potatoes grew well, especially the root growth of those crops was very good. The water culture solution was used in this experiment. The fog-box might be used for morphological, ecological and physiological studies on the root, rhizome or tuber of crops, but it appeared that further investigations on the structure and function of fog-box for special purposes of studies were required .
