PURPOSE: To obtain a plant having extension of peduncle, stem and root and high commercial value by equipping a culture stand with a vibration generator system and culturing the plant on the culture stand to vibrate the plant from the outside and to activate function of the plant of their own.

CONSTITUTION: A culture stand 1 is provided with a vibration generator system 2 consisting of a motor 4 and an eccentric flywheel 5. Culture plant 3 is placed on the culture stand 1, the vibration generator system 2 is operated for 30 minutes daily to vibrate the culture stand 1. The vibration corresponds to natural wind, vibration of soil makes the culture plants readily come into contact with air and synergistic effects such as suppression of mold and blight are obtained by ventilating effects.
