Abstract:: Taking irrigation with tap water as contrast treatment, the experiment of using reclaimed water to irrigate eight common landscape plants (Euonymus japonicus, Ligustrum lucidum, Rosa chinensis, Syzygium aromaticum, Cercis chinensis, Forsythia suspensa, Chaenomeles speciosa and Prunus triloba) had been carried out for nearly three years. The influence of irrigation with different water quantities on soil properties of different landscape plants rhizosphere was studied. The results showed that some elements that the plant growth needs were contained in the reclaimed water, and most of these elements could be absorbed effectively by the plants, but a few deleterious elements in the reclaimed water were restrained. In contrast with tap water irrigation, reclaimed water irrigation enhances adversity resistance appreciably. The difference between reclaimed water irrigation and tap water irrigation is small in terms of most mineral elements, but the sodium element accumulation appears in all the leaves of eight plants, and so are the heavy metals. There is no obvious difference on the appearance of all the plants. Compared with contrast, pH has no significant difference between the soil irrigated with reclaimed water and control, and soil total salt, water soluble sodium and chloride ion content are higher than CK. Reclaimed water irrigation enhances the soil nutrients and soil enzyme activities, while the difference of the contents of soil nutrients and soil enzyme activities is not obvious. For the aspect of soil microbes, irrigation with reclaimed water accelerates the growth of soil microbes, especially for the soil bacteria quantities of Ligustrun lucidum, Rosa chinensis and Cercis chinenis. In the mine soil, bacteria amounts are predominant (more than 99.3%), actinomyces amounts are the next, and fungi amounts are the least among composition of three communities of soil microbes. In summary, irrigation with reclaimed water improve the soil nutrients, soil enzyme activities and soil microbes, also obviously promote landscape plants growth amounts in a short time.
