摘要
利用比色法和扩散法对金强河地区和甘肃农业大学校园内的土壤脲酶活性进行了分析。结果表明:比色法和扩散法测定的土壤脲酶活性平均值分别为(0.531±0.207)mg/g和(0.446±0.204)mg/g,两种测定方法的结果和变异系数差异均不显著(P>0.05)。但从试验操作方面考虑,扩散法操作比较简单、所用药品种类少、时间短,是一种比较可行的土壤脲酶活性测定方法。
By using the methods of colorimetry and diffusion,the activities of soil urease were tested in the area of Jin-qiang River in Tianzhu,Gansu and in the campus of Gansu Agricultural University. The results indicate that differences between the two methods were not significant, and the diffusion method was much easier to be done than colorimetry.
