摘要
指出了城市污泥的合理化利用一直是研究者们关注的一个热点问题。主要讨论了掺加不同质量比例的城市污泥用于制作复合基质对边坡高羊茅的生长影响,包括生长状况、叶长、根长等,目的是为城市污泥的绿色利用提出合理化建议和可行的途径。实验结果表明:城市污泥制作的生态基质能够明显促进高羊茅的生长,与不施用化肥和施用化肥对照相比,掺加污泥比例为30%的生态基质对高羊茅的生长效果促进效果最好,发芽率、根长、苗高均有显著提高。因此,提出了将城市污泥用于制作生态基质,既可以解决城市污泥的绿色利用问题,又可以促进植物的良好生长,是一个资源合理化利用、绿色环保的有效方法。
The rational utilization of urban sludge has always been a hot issue for researchers.This paper mainly discusses the effect of different mass ratio of urban sludge on the growth of Festuca arundinacea,including growth status,leaf length,root length,etc.,in order to provide reasonable suggestions and feasible ways for the green utilization of urban sludge.The results showed that the ecological substrate made of municipal sludge could significantly promote the growth of tall fescue.Compared with the control of no fertilizer and chemical fertilizer,the ecological substrate with sludge ratio of 30% had the best effect on the growth of tall fescue,and the germination rate,root length and seedling height were significantly improved.Therefore,using urban sludge to make ecological matrix can not only solve the problem of green utilization of urban sludge,but also promote the good growth of plants,which is an effective method of rational utilization of resources and green environmental protection.
