| 摘 要： | 研究了城市污泥堆肥生产草坪基质的应用效果。试验结果表明，城市污泥堆肥基质能明显提高黑麦草的地上和地下生物量和叶绿素含量，与不施化肥和施用化学的对照相比，城市污泥堆肥可以增加土壤有效态氮、磷含量，促进植物叶片对氮的吸收，提高草坪的质量。用经过无害化处理的城市污泥生产草坪基质，既可以解决城市污泥的出路，又可以降低草坪的生产成本，是一条经济可行的途径。

| Abstract: | Sewage sludge is a by-product of wastewater treatment plants, which receive a great deal of effluents from industrial, municipal and/or rural sources. According to the national planning, an increase of sewage sludge production will occur in China very soon. So, more attention should be paid to its disposal. Sewage sludge has several characteristics: (1) it contains organic matter; (2) the organic fraction contains humic substances coming from the degradation of organic matter; (3) it contains varying concen... |
