不通气

My nose is bunged up with a cold.

于感冒我的鼻不通气。

This room seems stuffy - open a window.

这好像挺不通气的，开一扇窗吧。

Or through high ridge in a field, covering terra, increasing the temperature of earth, increasing the thickness of dust and frowst in the day time can all be the methods of toting temperature.

起高垄、覆地膜，提高土温，增加热土厚度，白天不通气或尽量少通气方法加温。
