Root hairs feed from the surface particles, therefore the internal surface area has a great influence on plant food in the soil.
根毛从土粒表面吸收养分，所以，土壤的内表面积对土壤中的植物养分有很大影响。
Soil water is the link of the continuum, which makes soil system, plant system and atmosphere system become a continuum by water absorption of root system and water evaporation of soil surface.
土壤水分通过植物根系和土面蒸发进入大气从而使三者成为一连续统。
Water deficit is influenced by the level of soil water potential at the root surface.
水分亏缺是受根系表面土壤水势高低影响的。
First, we take the surface soil of the side slope as root-soil complex material and take the root as 3d reinforcement material to increase the soil strength.
首先，将边坡上的表层土视为根-土复合材料，草根可视为带预应力的三维加筋材料，使土体强度提高。
