Research progress on application of reclaimed water for irrigating greening plants

Reuse of reclaimed water was one of the most efficient means for resolving water shortage of city. The paper summarized the recent research work on the influence of reclaimed water to greening plants, which showed that there were positive and negative influences, and it was correlated with the quality of reclaimed water, irrigation models, plant species, soil type and irrigation time. The results showed that reclaimed water irrigation could affect plant growth characteristics, stress resistance physiology, photosynthesis and nutrition level, but it would not affect the normal growth. At the same times, the irrigation with reclaimed water would not cause the accumulation of contamination ions such as sodium, chlorine, boron, and heavy metals. So, it was feasible to irrigate the greening plants with reclaimed water.
