再生水灌溉对绿地植物影响的研究进展

Research progress on application of recycled water for irrigating green plants

我国近年出现了水资源紧缺的状况,开发利用再生水用于灌溉绿地植物是行之有效的路径之一,为了更好的使再生水在绿地植物中广泛应用,以及提供更加完善的依据与指导,需要加强再生水灌溉绿地植物的相关研究工作。本研究总结了再生水灌溉对绿地植物影响的最新研究进展,认为再生水灌溉可以促进绿地植物的生长发育、改变生理特性、优化形态品质、增加矿质元素的吸收和增强综合抗性等优点,同时因植物种类、水质的不同再生水灌溉会对植物造成一定的影响,如微量元素的变化,重金属及钠离子的累积。因此本研究就再生水灌溉绿地植物的可行性及可能存在的问题和今后的重要研究方向综合论述。

Recycled water has been widely used for irrigating green plants.The latest research work on the influence of recycled water on green plants is summarized and showed that recycled water can promote green plant growth,change physiological characteristics,optimize quality,increase mineral elements absorption and enhance the comprehensive advantages of resistance.However,because of different plant species composition and quality of recycled water,it may cause certain negative impacts,such as microelement changes,and heavy metal and sodium ion accumulation.This article briefly discusses the feasibility and possible problems associated with use of recycled water for green plants,and indicates important research directions for the future.
