摘要
采用室内模拟的方法对残膜影响土壤水分运移进行了研究。结果表明,残膜会阻碍土壤水分向上移动,而且残留量和残膜面积越大,阻碍作用越明显。此外,残膜对土壤水分下渗有一定的促进作用。
The effects of residual mulch film on the migration of soil water were studied by using simulation method. The results showed that residual mulch film could hinder the upward migration of soil water, and the hindering effect increased with the increasing of the amount and area of residual mulch film. Besides, residual mulch film had the role in promoting the infiltration of soil water.
