摘要
对比分析了地膜覆盖和秸秆覆盖条件下春小麦棵间蒸发过程,以土壤热通量为大气因素,土壤温度、土壤水分为土壤因素,作物株高为作物因素,采用通径分析方法,研究了石羊河流域春小麦地膜覆盖和秸秆覆盖措施下影响棵间蒸发的因素。研究认为,土壤是影响春小麦棵间蒸发的主要因素。其中地膜覆盖条件下,土壤温度是影响棵间蒸发的重要因素和限制因素,秸秆覆盖条件下,减小土壤含水率将显著降低春小麦棵间蒸发量。
The paper analyzed soil evaporation of spring wheat under film and straw mulch respectively,and used path analysis method to research influencing factors of soil evaporation with different mulch material taking soil heat flux as atmospheric factor,soil temperature and soil water as soil factor,and plant height as crop factor.It was believed that soil factors were the main one to soil evaporation,and soil temperature was the most important and limitation under film mulch,and soil water played a main role in controlling soil evaporation under straw mulch.
