摘　　要： 为了研究猪场沼液灌溉冬小麦后,对土壤有机质、全氮、全磷以及铜、锌等金属元素含量变化的影响程度,笔者通过田间试验的方法对规模化猪场沼液灌溉冬小麦进行研究,重点研究沼液利用对土壤质量和生态安全的影响。结果表明,沼液处理使表层土壤有机质增加达3.0kg/hm2,全氮含量提高65%,土壤pH值下降0.4个单位,土壤铜、锌、铅、镉含量符合《小麦产地环境技术条件》NY/T851—2004的要求。本研究结果仅说明沼液以大田灌溉方式利用在短期内不会造成土壤质量下降和土壤环境污染,长期灌溉的影响需进一步研究确定。 The objective of this study is to determine the effect of using anaerobic effluent of swine farm wastewater for winter wheat irrigation on soil contents of organic matter,total nitrogen,total phosphorus,copper,zinc etc.A field plot experiment was carried out to investigate the effect of irrigating winter wheat with anaerobic digested swine farm wastewater（ADSFW）on soil quality and ecological safety.The results showed that the organic matter content of the surface soil of the ADSFW irrigation treatment increased up to 3.0 kg/hm2,and total nitrogen content increased by 65%,while pH down 0.4,and copper,zinc,lead and cadmium content all met the requirements of NY/T 851-2004.These results only indicated the use of ADSFW in field irrigation would not result in the short term decline in soil quality and cause soil pollution,and the impact of long term irrigation needed further research to determine.
