Effects of shortterm irrigation with reclaimed water onsoil microbial quantity of greenbelt

The simulation experiment with soil column was carried out to determine the effects of shortterm irrigation with reclaimed water on seasonal dynamic changes of microbial population in the root soil layer of greenbelt. The results of this study showed that the shortterm irrigation with reclaimed water increased the quantity of bacteria, fungus, actinomycete in soil when compared to clean water. The change of soil microbial quantity showed a single peak curve from May to November, and peaked in July or August. The differently changeable trends of soil microbial quantity were found in this study among six plants, which was possibly related to the biological characteristics of plants.
