城市污泥堆肥对12种花灌木生长的影响

Effects of Sewage Sludge Compost on the Growth of 12 Flowering Shrubs

以城市污水处理厂堆肥污泥为研究对象,采用田间试验方法开展了污泥土地利用对12种花灌木生长的影响研究。结果表明,污泥堆肥的不同用量处理与对照相比,12种花灌木的株高、冠幅都有不同程度的增加。施用污泥堆肥的株高比同期的对照处理增长了13%~28%,冠幅增加了26%~48%;处理量5.0%是各花灌木生长的最佳投放量。污泥堆肥使它们的开花、结果习性产生了一定程度的变化,对提高它们的开花质量有一定的促进作用。

In order to use sewage sludge as a resource,effects of sewage sludge compost on the growth of 12 flowering shrubs were studied in field.The results showed that compost could be advantageous to the plant heights and crown diameters.The plant heights and crown diameters in different levels of sewage treatment increased by 13%-28%,26%-48%,respectively compared with the control.The best collecting volume for flowering shrubs was 5.0%.It has a certain impact on the quality of flowering and fruiting.
