- 摘要:
- 在新疆沙湾县连续进行的 4年大田地温与气温观测实验基础上，重点对玉米与棉花在地膜覆盖下的土壤层（0～25 cm）温度特性进行了分析，结果表明地膜覆盖对土壤层有明显的增温效应。气温的年变化和日变化都有一定的规律可循；覆膜后的土壤耕作层地温比不覆膜地温值高，且随深度不同而在变化。
- Abstract:
- On the basis of the continuous four years observation and experiment on the temperatures of soil and air in big farmlands in Shawan county of Xinjiang.The charactrtistics of the temperature in the soil layers under the condition of the corn and cotton covered with film, the result shows there is an apparent effect on increasing temperature when the soil layers covered with film. There are some regulars about the annual and daily change in temperature; the temperature of plough layer covered with film is higher than that without using film, and it changes with the depth.
