| Abstract: |
| By using real-time monitoring and positioning mathematical simulation methods and selecting the typical water and wind erosion area in Shenmu in north China as the testing site, continuous determination was conducted of the ground temperature and soil moisture on different depths among six measures such as no-tillage, straw mulching and plastic film mulching. The results showed that: ridge plastic film mulching improves the ground temperature best, either for specific time at different depths or for the same depth at different times the ridge plastic film mulching treatment with the highest soil temperature. Its accumulated temperature is 10% higher than comparison treatment; and the soil temperature in straw mulching treatment is lower than the comparison treatment，while the accumulated temperature in straw mulching treatment is 2.3% lower than comparison treatment. This test has important practical and theoretical guidance value in selecting the best cultivation measure in ecologically fragile areas with water and wind erosion. |
