摘  要:
选取北京市怀柔区水库附近一处坡地栗园作为试验地,用表土改良剂(聚丙烯酰胺,PAM)和土壤保水剂(SAP)进行坡地栗园的肥料污染防治,通过人工降雨试验方法对PAM的防污效应进行了研究,同时进行为期2年(2010~2011年)的野外监测试验,研究了技术应用以后坡面水土和养分流失,土壤剖面墒情和氮素运移等情况。结果表明:PAM减小坡面次降雨径流氮素平均质量浓度和污染物排放负荷的幅度分别为5%~8%和16%~22%,其中PM的处理减少坡面氮素流失方面效果最好;与未施加化学制剂的对照PS0相比,化学制剂联合处理组PS1、PS2分别提高根层土壤含水率10.4%、23.7%,提升根层氮素含量3.8%、22.3%,减少坡面径流含沙率30.7%、61.7%,减少坡面径流硝态氮流失14.7%、30.7%。

摘  要:
Taking hillside orchards in Huairou district as the experimental plot,PAM and SAP were selected to apply for controlling manure pollution in this orchard.The antifouling effect of PAM on sloping field was tested by artificial rainfall experiment,and the outdoor monitoring experiment was carried out from 2010 to 2011.After applying the proposed technology,soil erosion and nutrient runoff in soil slope,also the soil water content and nutrient migration in soil profile were discussed.The results showed that PAM could reduce event mean concentration and pollution emission load of individual rainfall by 5% ~ 8% and 16% ~ 22%,respectively.PM treatment is the best in this experiment.Compared with control treatment PS0,chemical antifouling treatments PS1 and PS2 could promote the water content of soil root layer by 10.4% and 23.7%,increase nutrient content by 3.8% and 22.3%,reduce sediment in slope runoff by 30.7% and 61.7%,and reduce nitrate nitrogen content in slope runoff by 14.7% and 30.7%,respectively.
