    摘要:

    選取北京市懷柔區(qū)水庫(kù)附近一處坡地栗園作為試驗(yàn)地，用表土改良劑（聚丙烯酰胺，PAM）和土壤保水劑（SAP）進(jìn)行坡地栗園的肥料污染防治，通過人工降雨試驗(yàn)方法對(duì)PAM的防污效應(yīng)進(jìn)行了研究，同時(shí)進(jìn)行為期2年（2010~2011年）的野外監(jiān)測(cè)試驗(yàn)，研究了技術(shù)應(yīng)用以后坡面水土和養(yǎng)分流失，土壤剖面墑情和氮素運(yùn)移等情況。結(jié)果表明：PAM減小坡面次降雨徑流氮素平均質(zhì)量濃度和污染物排放負(fù)荷的幅度分別為5%~8%和16%~22%，其中PM的處理減少坡面氮素流失方面效果最好；與未施加化學(xué)制劑的對(duì)照PS0相比，化學(xué)制劑聯(lián)合處理組PS1、PS2分別提高根層土壤含水率10.4%、23.7%，提升根層氮素含量3.8%、22.3%，減少坡面徑流含沙率30.7%、61.7%，減少坡面徑流硝態(tài)氮流失14.7%、30.7%。

    Abstract:

    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.
