| Abstract: |
| Comparison was made of effects of three different mulching ways applied to tobacco field experiment, and the results showed that mulching treatment enhanced obviously the activity of soil peroxidase and soil sucrase, while it restrained the activity of soil urease to a certain extent. As compared with contrast and plastic film mulching treatments, liquid film mulching improved significantly the activity of soil peroxidase, and the activity was increased by 5.72% and 23.19% respectively on the average at vigorous growing stage of tobacco, and the differences of two mulching treatments reached significant level (P>0.05). At the same time the activity of soil sucrase under mulching treatment increased by 0.8% in comparison with contrast treatment, but the differences of three treatments didn′t reach significant level (P>0.05). Tobacco leaves under Fv/F0 & Fv/Fm of mulching treatments were significantly larger than contrast treatment, and their differences reached significant level (P>0.05), while the effect distinction of chlorophyll fluorescence parameter was not significant under plastic film mulching and liquid film mulching, and their effect was equivalent. |
