Abstract: A columnar cultural system, which contained 77 columns (200 cm in height, 15 cm in diameter) in 160 m2 area in a glass house, carried flower plants of 53 species in 25 families and looked as if a “flower forest". The cultural result showed a harmonious ecological relation among the different flower plants while all of them had been irrigating with a same nutrient system and offered a theoretical base for the mixed flower column used on the balcony culture. The different flower columns with different interests could be composed with different flower chose arbitrarily from the columnar cultural system for the cultures on the balcony. Besides this, these flower columns possessed also other several advantages. The columns were of different heights from 50 cm～200 cm and portable to carry. The column could be turned round the spindle, so the plants grown on the column could get sun light uniformly. The basin used as the bottom of column was the reservoir with the island, which made the column a solid foundation, but also could contact the other column to enlarge the cultures. There were both irrigating systems manually and automatically, so labor and time were saved and cleaing was kept.
