| 英文摘要: |
| The relationship between soil nutrients and enzymes in the area of Shangluo were studied through path analysis for data processing. The results show that the soil total nitrogen and alkali-hydro nitrogen in the area of Shangluo have significant effects on the activity of invertase, and they are the main factors on the activity of invertase. Soil total N and available K have strong direct and indirect effects on the activity of catalase, and the interactions of them also have great effects on the activity of catalase, and they are the main factors on the activity of catalase. From the correlations of these factors, we can fingure out that the activity of soil enzymes can be used to assess soil fertility condition. |
