Experimental study on the inhibition effect of Coleus blumei on alga growth
The inhibition effect of Coleus blumei on the growth of alga was investigated by the artificial control of nutrition,light and temperature of the laboratory test. The variation of soluble phosphorus in the test was detected, and the inhibition effect of Coleus blumei and Eichhornia crassipes to algae was compared. The experiment results showed that the hydroponics Coleus blumei significantly reduced the algae density in culture medium, the variation of soluble phosphorus in culture medium with hydroponics Coleus blumei was in consistent with that without hydroponics Coleus blumei, which indicated that inhibition effect of hydroponics Coleus blumei was not due to the nutrient absorption. The comparative test revealed that hydroponics Coleus blumei presented similar algal inhibitory effect with Eichhornia crassipes.
