Radial Oxygen Loss and Pollutants Removal of Plants Cultivated on Ecological Floating Beds

Abstract:

Radial oxygen loss (ROL) from roots of reed, typha and wild rice stem was investigated. Root excretion oxygen showed that the rates of the ROL increased with the illumination time under hard light intensity. For each plant, the ability that roots excreting oxygen under different light intensities decreased successively in the order of hard light, non-light and weak light. The ROL was different with the increased sequence of typha, wild rice stem and reed. The local available reed and typha could remove the pollutants effectively in the pilot test with the average removal rates of 41.99%, 28.47%, 48.38% and 48.76%, respectively.
