| 摘 要： | 对冻期土壤的水分、温度和盐分的变化规律进行了定量测定,并对其在裸地与地膜覆盖地的运动规律进行了比较,得到了冻土水热盐运动的一些重要特性,冬季覆盖可提高土壤温度,保持较高的含水率,减少土壤表层含盐量,提出了冬季覆盖是防春旱、春寒和土壤次生盐碱化的较为有效的途径。

| Abstract: | The paper is about field experiment of water-heat-salt movement of freezing-thawing soils in Yucheng Experimental Station,Shandong Province. The results of bare soil surface and plastic film mulched soil surface are compared and discussed. Mulching can increase the soil temperature, remain high water content and decrease the salt content in subsurface soil. So mulching through winter to next spring is a reasonable method to prevent the soil from suffering cold and arid, and decrease the salinity of the soils. |
