摘要
文章研究了再生水灌溉对园林植物叶片中主要的矿质元素与重金属元素的含量以及植物生长发育的影响。试验结果表明:使用再生水灌溉的园林植物,与使用自来水相比,叶片中部分矿质元素与重金属元素的含量有不同程度的升高,部分的含量则有不同程度的降低;同一种元素在不同植物上的含量,呈现出不同的变化,升高或降低的幅度也不同;使用再生水灌溉的园林植物在外观上没有出现明显的异常现象,而且生长发育良好。
In this paper,the effect of the reclaimed water irrigation on the concentration of leaf mineral elements and leaf heavy metal elements,and the plant growth were studied.The results showed that,compared with the tap-water irrigation,the concentration of some leaf mineral elements and leaf heavy metal elements of reclaimed water irrigation increased,while the others decreased.The dynamics of the same element varied with the different plants.The garden plants applied reclaimed water irrigation did not display obvious normal phenomenon in appearance and grew well.
