液体介质渗透速率 liquid media penetration rate
The permeability of surface layer of farmland is stronger, along with the increase of depth, permeability rate reduces rapidly ranged from 20 to 40cm, but below 40cm it gradually increased. This tendency is different from that of undisturbed black soil.
耕地的表层土壤渗透能力较强,随着深度的增加,在20～40cm渗透速率急剧减小,而在40cm以下渗透速率又逐渐增大,与未经干扰黑土呈现出不同的渗透变化规律。
