【摘要】：以安新地區(qū)高速公路邊坡坡面農(nóng)業(yè)土壤為研究對象,通過分層取樣的方法,對不同深度土壤的pH、有機質(zhì)、堿解氮、有效磷和速效鉀含量進行對比分析,探討高速公路對周邊不同深度土壤肥力的影響。結(jié)果表明:邊坡不同深度農(nóng)業(yè)土壤的有機質(zhì)、堿解氮、有效磷、速效鉀含量不同,調(diào)查范圍內(nèi)的土壤質(zhì)地以粉砂質(zhì)粘壤土為主,以壤質(zhì)砂土為輔。高速公路對邊坡不同深度土壤有機質(zhì)含量的影響最大,其次是有效磷,影響最小的是速效鉀,pH也受邊坡不同深度土壤的影響。由此可見,安新地區(qū)高速公路能夠?qū)吰虏煌疃韧寥赖姆柿顩r產(chǎn)生一定的影響。
[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.
