为探讨土壤理化性质对土壤硝化势的修正作用,采用室内模拟的方法,测定了我国10种典型农田土壤的潜在硝化势,并利用数理统计分析方法探讨了土壤理化指标于土壤硝化势的之间的相关性.结果发现,不同质地的土壤潜在硝化势存在的差异较大;土壤硝化速率与pH、OC、CEC、Clay等表征土壤质地的理化指标之间均存在显著的相关性;且随着土壤理性性质参数的增加,多元回归方程的R2也随之增加.
為探討土壤理化性質對土壤硝化勢的脩正作用,採用室內模擬的方法,測定瞭我國10種典型農田土壤的潛在硝化勢,併利用數理統計分析方法探討瞭土壤理化指標于土壤硝化勢的之間的相關性.結果髮現,不同質地的土壤潛在硝化勢存在的差異較大;土壤硝化速率與pH、OC、CEC、Clay等錶徵土壤質地的理化指標之間均存在顯著的相關性;且隨著土壤理性性質參數的增加,多元迴歸方程的R2也隨之增加.

To determine the correction of the nitrification potential under different soil texture, potential nitrification of 10 main agricultural soils in China was tested in laboratory simulation ex- periments. Mathematics and statistical methods were used to analyze the relationship between po- tential nitrification and soil properties in different soil types. It was found that there was signifi- cantly different in potential nitrification among the different soil type, and it had significant rela- tionship with the selected soil properties. Multiple regression statistical analysis showed that the regression coefficient (R) between the potential nitrification and soil properties also increases, as more soil parameters were introduced in multi regression equation.
