摘要/Abstract

摘要： 用三种稀释倍数的城市生活污水[污水:清水(v/v)为1:0、1:0.5、1:1]处理金盏菊种子及盆花,结果表明,污灌处理不仅显著地降低种子的萌发率,还增加萌发后幼苗病害的发生率;未经稀释的原生污水显著抑制金盏菊幼苗的生长,而稀释后抑制作用降低,当稀释至适当浓度时,则对幼苗生长起促进作用;对于金盏菊成年植株,污灌处理(不论稀释与否)显著地增加其茎、叶和根的鲜重,分别较对照增加161.63%~215.12%、86.77%~109.23%和23.89%~34.13%。综合分析表明,原生污水经过适当稀释后用于草花污灌,可以使污水中的营养盐得到回用,提高草花的观赏性。

Abstract: The seeds and potted plants of Calendula officinalis were treated with municipal domestic sewage effluents. The treatments were divided into 4 groups according to effluents:tap water(v/v):I, 1:0; Ⅱ, 1:0.5; Ⅲ, 1:1; control, 0:1. Compared with the control, sewage irrigation treatments (I, Ⅱ and Ⅲ) obviously reduced the rate of seed germination and increased the disease incidence of seedlings. The undiluted raw sewage could remarkably restrain the seedling growth, and the retarding effect could be relaxed by diluting with tap water. Furthermore, the diluted sewage of proper concentration could improve the seedlings growth. Compared to the control, sewage irrigation treatments increased the fresh weight of the stem, leave and root of full-grown C. officinalis plant by 161.63%~215.12%, 86.77%~109.23% and 23.89%~34.13%, respectively. The results of this study showed that the diluted sewage could be reused in irrigation and the nutrient elements in the sewage effluents could increase the ornamental value of herbage flowers.
