| 摘 要： | 分析了全国规模化生猪养殖和污染现状,并开展了"猪-沼-草"生态模式治理规模化猪场污染研究。结果表明,规模化猪场采用"猪-沼-草"生态模式,配套足够的草地面积,完全可以消纳规模化猪场产生的污水,生产出大量牧草,还能起到很好的改良土壤效果,但长期种植禾本科牧草且只施沼肥的草地需要补施钾肥,以弥补土壤钾养分过度流失。

| Abstract: | The dissertation analysis the pollution situation of scale pig-breeding in China.We studied the effect of an ecological model of "Pig-Methane-Forage" on pollution control.The results showed that the ecological model of "Pig-Methane-Forage" could completely eliminate sewage water from scale pig-breeding farms under the condition of large-area grassland.Number of forage product from the ecological model,and an ideal result had been achieved on soil amelioration.But loss of K element was found in grassland fertilized by methane in long-term.So,fertilization of K element would be needed for grassland management. |
