沼液灌溉对园林树木土壤重金属含量的影响
Effects on soil heavy metal contents under Garden Trees irrgated by biogas slurry from livestock manure
摘要
Abstract
In this paper, 6 kinds of garden trees were used to study the response mechanism of spraying biogas slurry, using pot control slurry irrigation method. The result showed that: Soil Cu content increased with increasing of biogas slurry concentration; which had significant difference from each other. Soil Pb content of Malus halliana, Hibiscus, Cherry, Osman-thus increased with increasing of spraying biogas slurry. It' s maximum value appeared in 10 L, while which of Viburnum awabuki、Ligustrum lucidum appear in 8 L, Cr content of deciduous species increased at first and decreased afterwards. It reached the maximum value in 8 L, while Cr content of evergreen tree increased and reached the maximum value in 10L. That s main all the mentioned heavy metals content increased with increasing of spraying biogas slurry, but which were below the limit of the National Soil Safety Standard(GB15618-1995). It indicated that an appropriate application of biogas slurry in soil-plant system achieved the resource utilization while no heavy metal contamination was pressured to soil and plant.关键词
