| 摘 要： | 摘要： 通过对两年不同栽培模式、不同土壤深度、不同生育时期旱地冬小麦土壤温度资料的分析表明，覆盖栽培并不能改变土壤温度的变化规律，平膜覆盖栽培返青期前能够显著提高0～25cm各土层温度，垄膜覆盖栽培在越冬前能够有效提高表层土壤温度，覆草栽培仅在出苗期有一定的增温效应，返青期以后表现为负效应。

| 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. |
