通辽污灌渠及土壤的硝态氮亚硝态氮含量分析

Analysis on Tongliao wastewater irrigation channel and soil nitrate nigrogen content

以内蒙古通辽市郊区污灌渠两侧农田为研究对象,通过采集污灌渠水样和渠两侧农田土壤样,进行了土壤氮元素含量分析,研究了灌渠和灌渠土壤氮元素硝态氮、亚硝态氮的含量分布及相互关系,以期为合理进行污水灌溉提供指导。

Taking both sides of irrigation farmland in Tongliao suburb of Inner Mongolia, by collecting water sample from wastewater irrigation channel and soil sample from both sides of farmland, it analyzes the nitrogen content in soil, studies distribution and mutual relationship of soil nitrogen nitrate nitrogen content and nitrite-nitrogen content, with a view to provide reasonable guidance for sewage irrigation.
