不同性状污泥对灌木的生长影响研究

Study on the Impact of Raw Sludge and Compost Sludge on Shrubs′ growth

选择不同量的生污泥和腐熟污泥替代化肥用于灌木的追肥试验,对榆叶梅的花朵/枝长、花期和紫薇、杠柳、山杏的发芽时间进行记录测定和比较分析,结果表明:腐熟污泥和生污泥对榆叶梅的生长有一定的促进作用,对紫薇的发芽总体上呈现出抑制的作用,在试验用量范围内对山杏发芽基本不造成影响,腐熟污泥抑制杠柳的发芽,随用量的增加,抑制作用有减弱趋势,生污泥始终抑制杠柳的发芽。

This study selected different dosage of raw sludge and compost sludge as an alternative fertilizer in the experiment of shrubs.In order to seek the impact on shrubs and provide basis for landscape application,the study measured and analyzed the ratio of flower quantity to branches length and florescence of flowering plum as well as germinating time of Crape myrtle,Periploca sepium and Siberian Apricot.
