摘    要:利用污泥堆肥和土壤按不同体积比例混合(污泥堆肥添加比例分别为0%、10%、25%、50%、75%和100%)作为草坪基质进行马尼拉草坪盆栽试验,分析污泥堆肥草坪基质利用对草坪生长及土壤和水环境的影响.结果表明,马尼拉的生长势随草坪基质中污泥堆肥添加比例的提高而增强;马尼拉的植物Hg含量与草坪基质的Hg含量存在较高相关性;草坪基质的Cr、Cd、Hg含量随污泥堆肥添加比例的提高而显著提高,但均未超过土壤三级标准;各处理淋溶液和草坪基质的重金属和氮含量存在较高相关性,本试验中当污泥堆肥添加比例达到50%以上时,淋溶液将出现Cd和硝酸盐浓度超标现象.

关 键 词:污泥堆肥  草坪基质  草坪生长  土壤和水环境

Abstract:To address effect of the sludge compost-containing medium on the growth of Manila lawn and environment quality, a pot experiment was conducted using six treatments based on contrasting sludge compost addition volume ratios in the soil system (i. e., 0%, 10%, 25%, 50%, 75% and 100%). The results indicated that the growth potential of Manila lawn was increased with increasing sludge compost addition volume ratio. The content of Hg in Manila plant was significantly positively correlated with that in the lawn medium. Although the contents of Cr, Cd and Hg in the lawn medium were synchronously increased with increasing sludge compost addition volume ratio in the soil system, their contents were all lower than the critical levels of third-class standard in the National Soil Environmental Quality Standard. The heavy metal and nitrate concentrations detected in percolating water were significantly positively correlated with those in the lawn medium, respectively. When the sludge compost addition volume ratio was more than 50% in this study, both heavy metal and nitrate concentrations in percolating water would exceed the maximum allowable levels of the National Groundwater Environment Quality Standard.
Keywords:sludge compost  lawn medium  lawn growth  soil and water environment
