摘要

揭示了不同层次土壤剖面电位和温度动态的形成特征。建立了土壤温度在其高正值范围内对土壤水分势动态的影响。水分势的所有降低都是由于水分含量的增加而发生的。其含量的增加是由于降水和从下层抽走水分造成的。在冬季和负温度时期,水分含量受到蒸汽水分扩散的影响,而在解冻的土壤中,水分以液体形式存在。

The influence of temperature on the moisture potential in sod-podzolic soil in the autumn and winter periods of the year
The formation features of the potential and temperature dynamics at different levels of soil profile are revealed. The influence of soil temperature in the range of its high positive values on the dynamics of soil moisture potential is established. All lowering of the moisture potential occurs due to an increase in the moisture content. The increase in its content occurs due to precipitation and by pulling moisture from the underlying layers. In winter and in periods with negative temperatures, the moisture content is effected by diffusion of vaporous moisture, and in thawed soil, in liquid form.
