| 摘 要： | 通过对整个冬季春季土壤在3种处理条件下地温变化的动态观测，对照免耕裸地的地温变化，分析了3种处理条件对地温影响的差异，表明，耕地覆膜处理能加速冻土的解冻过程，使冻土提前解冻，迅速提高地温。

| Abstract: | During winter and spring regimes of the soil temperature in farmland?unploughed land covered with plastic film and farmland covered with plastic film are different in different freezing-thawing period, and the effect of increasing temperature is different in different soil depths. The soil temperature profiles of four fields with different treatments were obtained,and the effect of the treatments on soil temperature were analyzed. The results show that farmland covered with plastic film can speed up thawing and enhance the soil temperature rapidly during winter and spring. |
