| 摘 要： | 通过无土栽培,研究了再生水对17种园林植物生长的影响。结果表明:再生水中所含有的植物生长所需的元素大部分可被植物有效吸收,而植物对一些有毒元素的吸收受到抑制;再生水提供的营养元素在短期内还不足以明显促进植物生长量;再生水可促进一些植物开花,使花期提前;与对照自来水相比,Na和Pb元素在植物体内含量偏高,可能影响植物正常生长,需要提高对这2种元素的处理程度,以适用于园林植物。

| Abstract: | Seventeen kinds of ornamental plants were soilless-cultured and the impacts of reclaimed water on ornamental plants have been studied.The results indicate:some elements that the plant growth needs are contained in the reclaimed water,and most of these elements can be absorbed effectively by the plant,but a few deleterious elements in the reclaimed water are restrained.The reclaimed water can promote some plants blooming,makes a florescence shift to an earlier date.The nutrition elements that reclaimed water... |
