| 摘 要： | 污泥的透水性差,难以干燥是污泥资源化利用的技术障碍。可以利用污泥的这一特性,开发污泥保水的新功能。以土培及玉米盆栽研究污泥不同含量与在土壤中不同放置方式的保水效果,对土培的含水量、失水量及失水率,盆栽土壤水分含量及植株生物量进行了系统分析。污泥含量高的处理有一定保水效果但不及保水剂处理,而其盆栽结果却优于保水剂处理。污泥在土层的不同放置试验表明,在土壤中层状放置的土培及盆栽试验结果均优于全层混合,且双层的效果最优。污泥具有较强的保水性,是有待开发的新功能。与在土壤合适的放置方式结合,可更好地发挥其保水潜力。

| Abstract: | Sewage sludge may be exploited as water retaining agent owing to its characteristics of low water permeability and drying rate,which were considered as the technical barrier of sewage sludge application.Plot and pot culture of corn were conducted in the experiment to study the influences of different content and placement of sewage sludge on water retention.Water content,water loss and water loss rate in plot culture together with soil water content and plant biomass in pot culture were measured and analyze... |
