摘要: 中水应用于城市绿地灌溉,可以拓展中水的应用范围,对于实现城市污水资源化有重要意义。通过土柱栽培试验,测定中水灌溉(清水对照)下9种绿地植物的生理反应。结果表明,中水灌溉会对绿地植物的生理机制产生一定的影响,与不同的植物种类有关;且叶片相对含水量、相对电导率、游离脯氨酸含量、丙二醛含量(MDA)、叶绿素含量及叶绿素荧光的变化具季节动态性。除黄金榕、叶子花和龙眼在中水和清水灌溉下MDA存在显著差异外(P<0.05),其余各绿地植物都差异不显著(P>0.05),由此表明不会对植物生长造成胁迫危害。

Abstract: The greenbelt irrigated by the reclaimed water can expand the range of the reclaimed water application, and has the important meaning for the realization of urban wastewater reuse. Adopting the soil column cultivation experiment, the physiology reaction of nine green plants irrigated by the reclaimed water (clear water irrigation as control) were determined, the results showed that the reclaimed water irrigation would produce certain effect on physiological mechanism of greenland plants, the effect was related with different plant species; and the relative water content of leaves, relative conductivity, free proline content, malondialdehyde (MDA), chlorophyll content and chlorophyll fluorescence has a tide of seasons dynamic changes. Except for the MDA content of Ficus microcarpa cv., Bougainvillea spectabilis, Litchi chinensis has significant difference (P<0.05) between under the reclaimed irrigation and the clear water irrigation, the other greenbelt plants has no significant difference (P>0.05). So it showed that the reclaimed irrigation will not harm to the growth of plants.
