Abstract: 【Objective】To make clear the relationship between Azolla wet-culture yield and energy consumption by yield test of wet cultured Azolla using different artificial light source energy consumptions.【Method】The Azolla yield comparison test using our original wet-culture device was carried out in the same wet-culture space with Three light intensity ranges set by T4 fluorescent tubes and five light resource settings.【Results】The Azolla wet-culture yield per unit area was highest when the light intensity on Azolla surface was 6000-7000Lux, and so was the yield per unit energy consumption per day. Too low (3000-4000Lux) and too high light intensity (9000-10000Lux) would decline the two yield indices. The Azolla wet-culture yield positively correlated with the amount and the length of root penetrated through the medium; in the same wet-culture space, the efficiency of energy transforming into yield would be improved by reducing the intervals between layers and the number of fluorescent tubes.【Conclusion】In the same wet-culture space, maintaining light intensity on Azolla surface between 6000-7000Lux and appropriately adding layers or reducing intervals between layers to adjust the artificial light source setting would reduce energy consumption and achieve the purpose that procuring higher yield with lower energy consumption.
