【摘要】：以安新地区高速公路边坡坡面农业土壤为研究对象,通过分层取样的方法,对不同深度土壤的pH、有机质、碱解氮、有效磷和速效钾含量进行对比分析,探讨高速公路对周边不同深度土壤肥力的影响。结果表明:边坡不同深度农业土壤的有机质、碱解氮、有效磷、速效钾含量不同,调查范围内的土壤质地以粉砂质粘壤土为主,以壤质砂土为辅。高速公路对边坡不同深度土壤有机质含量的影响最大,其次是有效磷,影响最小的是速效钾,pH也受边坡不同深度土壤的影响。由此可见,安新地区高速公路能够对边坡不同深度土壤的肥力状况产生一定的影响。
[Abstract]:Taking the agricultural soil on the slope of highway slope in Anxin area as the research object, the contents of pH, organic matter, alkali-hydrolyzed nitrogen, available phosphorus and available potassium in different depth soil were compared and analyzed by stratified sampling method. The effect of expressway on soil fertility at different depth around the highway was discussed. The results showed that the contents of organic matter, alkali-hydrolyzed nitrogen, available phosphorus and available potassium in agricultural soil of different depth of slope were different. The soil texture in the investigation range was mainly silty clay loam, supplemented by loamy sandy soil. The influence of expressway on soil organic matter content in different depth of slope was the biggest, followed by available phosphorus, and the influence of available potassium pH was also affected by the soil of different depth of slope. It can be seen that the expressway in Anxin area can affect the soil fertility at different depth of slope.
