Abstract:

Abstract: Soil temperature date under different mulching modules and different depth and different growth stage of winter wheat in dryland was analyzed. The results showed that overlaying cultivation can't change the variety regulation of soil temperature. Film mulching and hole sowing cultivation remarkably increase 0～25cm soil temperatures before green-turning stage, Furrow-film mulching cultivation effective increase surface layer soil temperatures before winterovering stage, Straw mulching cultivation has effect of increasing soil temperature in seedling stage, and decreasing soil temperature after green-turning stage.
