Abstract: Hydroponic culture plants come into fashion in recent years.When the solution is exposed in the sunlight, algae will generate quickly and it is not good for the growth of plants.In the experience, active carbon, charcoal and VT-500 were added in the nutrient solution to study the inhibitory effects on algae in the plants hydroponic culture.The results showed that notable effects of the algae inhibition and stable level of pH were obtained when treated with active carbon in the solution.The effects of active carbon treatment were better than that of charcoal treatment and VT-500 treatment produced no good results for algal inactivation.

Key words: hydroponic culture, algae, active carbon, charcoal, VT-500
